Description

3D printer output and assembly method using it {3D PRINTED PRODUCT AND ASSEMBLY METHOD USING THE SAME}

The present invention relates to 3D printer output and an assembly method using the same, and more specifically, to a method of forming a output structure to facilitate coupling between 3D printer outputs and assembling the 3D printer output using this.

A 3D printer is a printer that can produce molded products in the three-dimensional shape of the real thing based on three-dimensional data created with a computer design program. Like 2D printers, these 3D printers use the XY orthogonal coordinate system and can print three-dimensional shapes by adding a Z axis.

3D printers include the FDM (Fused Deposition Modeling) method, which pulls out solid plastic materials that melt in heat like threads and melts them little by little and stacks them, as well as the SLA (StereoLithography Apparatus) method, which uses the principle of injecting laser light into photocurable resin to harden the injected area. In the SLA method, functional polymers or metal powders are used instead of photocurable resin, and the SLS (Selective Laser Sintering) method uses the principle of solidifying and molding by scanning laser beams. Light is irradiated to the lower part of the storage tank where the photocurable resin is stored. There is a DLP (Digital Light Processing) method that uses the principle of partial hardening.

A 3D printer using the FDM method includes an extruder and a bed, and filaments of various materials are supplied to the extruder. The FDM method can form a designed shape by heating and discharging filament and stacking it sequentially from the bottom of the bed.

When manufacturing a sculpture using FDM-based 3D printing, all outputs created at once are manufactured in a connected state, so when producing for assembly purposes, each output can be created individually and then combined to produce a single sculpture.

However, in the case of FDM-type 3D printing output, which produces a 3D printer output by supplying filament to the 3D printer extrusion unit and sequentially stacking it on the top of the bed, as shown in Figure 1, the 3D printer output has a stacked surface between layers. It will be included. At this time, the part containing the laminated surface of the 3D printed output is more vulnerable to external force than the part made of a single layer and can be easily damaged. Therefore, when the protrusions formed on the 3D printer output include the lamination surface as shown in FIG. 1 for combining each output, the protrusions can be easily broken by external force applied from the side of the protrusions or easily damaged when combining the outputs. Accordingly, the stability of the sculpture formed by combining the output may be reduced.

Accordingly, there is a need for the formation of effective 3D printed output and an assembly method using the same.

The present invention is intended to solve the above problems and provides 3D printed output.

Additionally, the present invention provides a 3D printed output and an assembly method using the same.

A connection fold groove in which a reinforcement layer is not formed is formed, and the connection part is folded so that the surfaces in contact with the top of the bed of the fixation layer are in contact with each other based on the connection fold groove after separating the three-dimensional structure from the bed. Provides a 3D printed output that forms a folded structure.

In addition, the present invention includes a 3D printer output step of outputting the 3D printer output on the top of the bed; A three-dimensional structure separation step of separating the 3D printer output from the bed after the 3D printer output output step is completed to obtain the three-dimensional structure individually; After completing the three-dimensional structure separation step, an inter-part bonding step of folding the connecting portion of the three-dimensional structure based on the connecting portion folding groove and joining the anchoring layer of the first part and the anchoring layer of the second part to come into contact with each other; and a three-dimensional structure combining step of combining the three-dimensional structures that have completed the inter-part bonding step with each other. Provides a 3D printed output and an assembly method using the same, including.

Referring to FIG. 2, the 3D printer output 1 may include a plurality of three-dimensional structures.

The 3D printer output 1 can be formed on the top of the bed 2 using a 3D printer. For example, the 3D printer output 1 may be formed by stacking a single layer or multiple layers on top of the bed 2, but is not limited thereto.

The 3D printer output 1 may include a plurality of three-dimensional structures. For example, the 3D printer output 1 may include a first three-dimensional structure 100 and a second three-dimensional structure 200, but is not limited thereto.

The three-dimensional structure of the 3D printer output (1) includes a first part that is three-dimensional, a second part that is three-dimensional and is spaced apart from the first part, and a reinforcement layer formed at the bottom of the first part and the second part. , a fixation layer formed at the bottom of the reinforcement layer and in contact with the top of the bed (2); and a connecting portion formed between the first part and the second part, wherein the fixing layer is connected and the reinforcing layer is extended.

At this time, the anchoring layer in contact with the top of the bed 2 may be formed as a single layer on the top of the bed 2.

For example, the first three-dimensional structure 100 of the 3D printer output 1 may include a first three-dimensional structure first part 110, a first three-dimensional structure second part 120, and a connection portion 130. .

For example, a first three-dimensional structure first part 110 that is stacked with a plurality of layers to form a three-dimensional shape, and a first three-dimensional structure first part 110 that is stacked with a plurality of layers to form a three-dimensional shape and is spaced apart from the first three-dimensional structure first part 110. It may include a second part 120 of the first three-dimensional structure formed. At this time, the reinforcement layer may be formed at the bottom of the first part 110 of the first three-dimensional structure and the second part 120 of the first three-dimensional structure. Additionally, the anchoring layer may be formed at the bottom of the reinforcement layer and in contact with the top of the bed 2.

In addition, it may include a connection portion 130 formed between the first three-dimensional structure first part 110 and the first three-dimensional structure second part 120, where the anchoring layer is connected and the reinforcing layer is extended. there is. Accordingly, the first part 110 of the first three-dimensional structure and the second part 120 of the first three-dimensional structure may be connected by the connecting portion 130.

A first part depression 111 may be formed in the first part 110 of the first three-dimensional structure 100, and a second part 120 of the first three-dimensional structure 100 may be formed. ) A second part depression (not shown) may be formed, but is not limited thereto.

In addition, for example, the second three-dimensional structure 200 of the 3D printer output 1 may include a second three-dimensional structure first part 210, a second three-dimensional structure second part 220, and a connection portion 230. You can.

For example, the first part 210 of the second three-dimensional structure is formed into a three-dimensional shape by stacking a plurality of layers, and the first part 210 of the second three-dimensional structure is formed into a three-dimensional shape by stacking a plurality of layers and is spaced apart from the first part 210 of the second three-dimensional structure. It may include a second part 220 of a second three-dimensional structure formed. At this time, the reinforcement layer may be formed at the bottom of the first part 210 of the second three-dimensional structure and the second part 220 of the second three-dimensional structure. Additionally, the anchoring layer may be formed at the bottom of the reinforcement layer and in contact with the top of the bed 2.

In addition, it may include a connection portion 230 formed between the second three-dimensional structure first part 210 and the second three-dimensional structure second part 220, connected to the anchoring layer, and formed by extending the reinforcing layer. there is. Accordingly, the first part 210 of the second three-dimensional structure and the second part 220 of the second three-dimensional structure may be connected by the connecting portion 230.

At this time, the first part protrusion 211 may be formed on the first part 210 of the second three-dimensional structure 200, and the second part of the second three-dimensional structure 200 ( A second part protrusion (not shown) may be formed at 220), but is not limited thereto.

The 3D printer output 1 may include various types of three-dimensional structures other than the first and second three-dimensional structures described as examples, but is not limited thereto.

For example, the line output 1000 is formed in contact with the top of the bed 2, and is fixed by connecting one three-dimensional structure to another, and may be connected to and fixed to one or more three-dimensional structures. Accordingly, the plurality of three-dimensional structures can be organized into one 3D printer output (1) to organically manage the plurality of three-dimensional structures.

In addition, when the 3D printer output 1 is formed on the top of the bed 2, a phenomenon may occur in which the outer portion of the three-dimensional structure is lifted from the bed 2 due to heat shrinkage, which may occur when the line output 1000 is formed on the three-dimensional structure. It can provide the effect of preventing lifting by fixing the outer shell of the structure. Accordingly, the shape of the three-dimensional structure can be stably formed.

Figure 3 is a schematic diagram of a three-dimensional structure according to an embodiment of the present invention.

Referring to FIG. 3, the three-dimensional structure includes a first part formed three-dimensionally, a second part formed three-dimensionally and spaced apart from the first part, a reinforcing layer formed at the bottom of the first part and the second part, and It may include a fixation layer formed at the bottom of the reinforcement layer and in contact with the top of the bed, and a connection part formed between the first part and the second part, where the fixation layer is connected and the reinforcement layer is extended. there is.

For example, the three-dimensional structure 10 includes a first part 13 that is formed in a three-dimensional shape by stacking a plurality of layers, and a first part 13 that is formed in a three-dimensional shape by stacking a plurality of layers and is spaced apart from the first part 13. It may include a second part (14).

Additionally, a reinforcement layer 12 may be formed at the bottom of the first part 13 and the second part 14.

In addition, a fixation layer 11 may be formed at the bottom of the reinforcement layer 12 at the bottom of the first part 13 and the second part 14 and in contact with the top of the bed 2. At this time, the fixation layer 11 may be formed as a single layer with a thickness of less than 0.6 mm. Accordingly, although it is easily bent by external force, flexibility is secured so that it is not easily damaged, and it can be easily folded based on the connection folding groove 16 of the connection portion 15, which will be described later.

In addition, it is formed between the first part 13 and the second part 14, and includes a connection portion 15 through which the fixation layer 11 is connected to connect the first part 13 and the second part 14. can do. At this time, the connection part 15 may be formed by extending the reinforcement layer 12 on the top of the fixation layer 11 of the connection part 15. Accordingly, the first part 13, the second part 14, and the connecting portion 15 share the anchoring layer 11 that abuts the top of the bed 2, and can be stably connected.

The connection portion 15 may include an anchoring layer 11 that is a single layer in contact with the top of the bed 2. For example, the anchoring layer 11 may be formed as a single layer with a thickness of less than 0.6 mm. Accordingly, although it is easily bent by external force, flexibility is secured so that it is not easily damaged, and the connection portion 15 can be folded based on the connection folding groove 16, which will be described later. Accordingly, the fixing layer 11 is bent based on the connecting portion folding groove 16, which will be described later, and the connecting portion 15 is folded and overlapped, so that the connecting portion 15 can have greater resistance to external force. For example, when the three-dimensional structure is combined by inserting the folded connection structure (Figure 5, 130-1), which is folded and overlapped based on the connection fold groove 16 described later, into the depression formed in the three-dimensional structure, the three-dimensional structure is more tightly combined. It can be fixed.

If the anchoring layer 11 is formed of two or more layers, the thickness of the anchoring layer 11 becomes thick and its flexibility decreases, so the connecting portion 15 may be damaged when folded based on the connecting portion folding groove 16, which will be described later. , layers that are vulnerable to bending may be separated or damaged. Accordingly, the anchoring layer 11 is preferably formed as a single layer.

The anchoring layer 11 of the connecting portion 15 may have a reinforcing layer 12 formed at the top. For example, the connection reinforcement layer 12 is formed on top of the anchoring layer 11 to an area less than that of the anchoring layer 11, and may be formed of one or more layers. Accordingly, it can serve as reinforcement to resist external force applied to the connection portion 15. Accordingly, the connection folding structure described later is formed by stacking the fixation layer 11 and the reinforcement layer 12, and the force applied to the connection folding structure is applied perpendicular to the stacking surface. Accordingly, stronger resistance to force applied perpendicularly to the laminated surface can be formed, and the connection folded structure can have greater resistance to external force, which can be advantageous in combining three-dimensional structures.

Since the reinforcing layer 12 is not formed in the connection portion 15, a connection fold groove 16 may be formed in which the top of the fixation layer 11 is exposed. For example, the connection folding groove 16 may be formed in a concave shape by exposing the top of the anchoring layer 11 in the gap between the reinforcing layer 12 and the reinforcing layer 12 where the reinforcing layer 12 is not formed. there is. Accordingly, when the three-dimensional structure 10 is separated from the bed 2 and then folded so that the surfaces in contact with the top of the bed 2 of the anchoring layer 11 are in contact with each other based on the connection folding groove 16, the reinforcement layer 12 ) The connection portion 15 can be easily folded and stacked along the portion of the single-layer anchoring layer 11 that does not include ).

The reinforcing layer 12 of the connecting portion 15 may be formed with a connecting protrusion 17 occupying a portion of the upper area of the reinforcing layer 12. For example, the connection protrusion 17 may be formed in a straight line from the first part 13 toward the connection fold groove 16, but is not limited thereto. Accordingly, the connection protrusion 17 may be exposed to the outer surface of the connection folding structure (FIG. 5, 130-1), which will be described later, and the connection folding structure (FIG. 5, 130-1) may be formed as a depression formed in another three-dimensional structure. When inserted and connected, the connection protrusion 17 may serve to fix the three-dimensional structure or the first part and the second part. In addition, the connection protrusion 17 can serve as an insertion guide when inserted into a depression formed in another three-dimensional structure, and prevents the first and second parts superimposed on the connection fold groove 16 from being distorted. It can be induced.

Figures 4 and 5 are schematic diagrams of the three-dimensional structure according to an embodiment of the present invention.

Referring to Figure 4, the connection part of the three-dimensional structure can be folded so that the fixation layer of the first part and the fixation layer of the second part come into contact with the connection folding groove.

For example, after the first three-dimensional structure 100 is separated from the top of the bed, the anchoring layers 132 adjacent to the top of the bed of the connection portion 130 are in contact with each other based on the connection folding groove 131 of the connection portion 130. It can be folded. Accordingly, the fixing layer 132 is bent based on the connection folding groove 131, and as the connection portion 130 is folded and overlapped, the connection portion 130 may have greater resistance to external force. For example, when the connection folded structure (Figure 5, 130-1), which is folded and overlapped based on the connection fold groove 131, is inserted into the depression formed in the three-dimensional structure to be described later and the three-dimensional structure is combined, the three-dimensional structure is more tightly combined. It can be fixed.

The connection folding structure (Figure 5, 130-1) is formed by stacking the anchoring layer 132 and the reinforcing layer 133, and the force applied to the connection folding structure (Figure 5, 130-1) is perpendicular to the stacking surface. It is inflicted with Accordingly, in the laminated structure, it shows stronger resistance to the force applied vertically to the laminated surface compared to the force applied horizontally to the laminated surface, so the connection folded structure (FIG. 5, 130-1) has greater resistance to external force. It can be advantageous in combining three-dimensional structures.

Additionally, the first part 110 of the first three-dimensional structure and the second part 120 of the first three-dimensional structure connected to the connecting portion 130 may contact each other. At this time, the anchoring layer in contact with the top of the bed of the first part 110 of the first three-dimensional structure and the anchoring layer in contact with the top of the bed of the second part 120 in the first three-dimensional structure may contact each other.

The connection folding groove 131 of the connection portion 130 may include one or more through holes 135 penetrating the anchoring layer 132. For example, one or more through holes 135 may be formed in the fixing layer 132 of the connection fold groove 131, like the connection part of a stamp. At this time, the through hole 135 may be formed in either a circular or polygonal shape, but is not limited thereto.

Accordingly, when the connection part 130 is folded based on the connection part folding groove 131, the connection part folding groove 131 can be folded more easily.

The reinforcement layer 133 of the connection part 130 may be formed with a connection protrusion 134 that occupies a portion of the upper area of the reinforcement layer 133.

The first three-dimensional structure 100 may include a depression. For example, the first three-dimensional structure first part 110 may include a first part depression 111 and the first three-dimensional structure second part 120 may include a second part depression 121, but is limited thereto. It doesn't work.

In addition, the first part depression 111 and the second part depression 121 form one depression when the first three-dimensional structure first part 110 and the first three-dimensional structure second part 120 come into contact with each other. It can be formed, but is not limited to this.

Referring to FIG. 5, the three-dimensional structure can be formed by folding the first part and the second part into contact with each other based on the folding groove of the connection part.

For example, the first three-dimensional structure 100 is folded so that the fixing layers adjacent to the top of the bed of the connection part contact each other based on the connection folding groove of the connection part, so that the first part 110 of the first three-dimensional structure connected to the connection part is formed. ) and the first three-dimensional structure second part 120 may be in contact with each other to form one structure.

At this time, the first three-dimensional structure 100 may have a connection folded structure 130-1 protruding from the outer surface of the first three-dimensional structure 100 formed by folding the connection portion as shown in FIG. 5 (a). For example, the connection folded structure 130-1 may protrude in a rectangular shape perpendicular to the outer surface of the structure of the first three-dimensional structure 100 formed by folding the connection section. Accordingly, the connection folded structure 130-1, in which the connection portion is folded in half and overlapped, can be more firmly fixed when inserted and coupled to a depression formed in another three-dimensional structure. At this time, the connection protrusion 134 may be exposed to the outer surface of the connection folded structure 130-1. Accordingly, when the connection folded structure 130-1 is inserted and coupled to a depression formed in another three-dimensional structure, the connection protrusion 134 serves to fix the three-dimensional structure and the three-dimensional structure or the first part and the second part. can do. In addition, the connection protrusion 134 can serve as an insertion guide when inserted into a depression formed in another three-dimensional structure, and the first three-dimensional structure first part 110 and the first part 110 are overlapped based on the connection fold groove. The second part 120 of the three-dimensional structure can be prevented from being distorted.

In addition, in the structure of the first three-dimensional structure 100 formed by folding the connection portion as shown in Figure 5 (b), the first part depression 111 and the second part depression 121 are A single depression may be formed. For example, the depression is formed by being depressed perpendicular to the outer surface of the structure of the first three-dimensional structure 100 formed by folding the connection part, and the first part depression 111 and the second part depression 121 may come into contact with each other to form one of the depressions. Accordingly, a connection folded structure or a protrusion formed in another three-dimensional structure may be inserted and coupled to the depression. This will be explained in detail through FIG. 6 described later.

Figure 6 is a schematic diagram of a depression according to an embodiment of the present invention.

In FIG. 6, the insertion members (A, A', A") may include the connection folding structure described as an example in FIG. 5 and a protrusion described later in FIGS. 7 and 8, and a 3D printer corresponding to the depression. It may be a separate output printed in a shape, but is not limited to this.

Referring to FIG. 6 (a), the first three-dimensional structure 100a includes a first part depression 111a formed in the first three-dimensional structure first part 110a that does not penetrate the first three-dimensional structure 100a, and a first three-dimensional structure 100a. The second part depression 121a formed in the one-dimensional structure second part 120a may form one depression. The one depression may be formed in a shape corresponding to the insertion member (A). For example, when the insertion member (A) includes a connection protrusion, one depression formed by contact between the first part depression (111a) and the second part depression (121a) is the connection part of the insertion member (A). It may be formed in a shape corresponding to the protrusion.

Accordingly, the insertion member (A) of a shape corresponding to the one depression formed by the first part depression 111a and the second part depression 121a can be inserted and fastened, and the first three-dimensional structure is formed. The first part 110a of the first three-dimensional structure (100a) and the second part 120a of the first three-dimensional structure may be fixed in contact with each other so that they do not spread apart and separate from each other.

Referring to FIG. 6 (b), the first three-dimensional structure 100b includes a first part depression 111b formed in the first three-dimensional structure first part 110b penetrating the first three-dimensional structure 100b, and a first three-dimensional structure 100b. The second part depression 121b formed in the second part 120b of the first three-dimensional structure penetrating the three-dimensional structure 100b may form one depression. At this time, the one depression may be formed in a shape corresponding to the insertion member (A).

Referring to FIG. 6 (c), the first three-dimensional structure 100c includes a first part depression 111c formed in the first three-dimensional structure first part 110c that does not penetrate the first three-dimensional structure 100c, and a first three-dimensional structure 100c. The second part depressions 121c formed in the one-dimensional structure second part 120c do not form a single depression, but may form depressions independently of each other.

For example, the first part depression 111c and the second part depression 121c do not form one depression, but the shapes of the first part depression 111c and the second part depression 121c are They may be formed in the same shape or may be formed in different shapes. Accordingly, the insertion member (A') of a shape corresponding to the first part depression 111c is fastened, and the insertion member (A") of a shape corresponding to the second part depression 121c is fastened, so that the two It can be assembled by combining the above three-dimensional structures.

According to the example disclosed in FIG. 6, two or more three-dimensional structures can be stably combined by inserting and fastening a folded structure or a protrusion of a connection part of another three-dimensional structure into a depression included in the three-dimensional structure, and two or more three-dimensional structures You can easily assemble a sculpture by combining it with each other.

Figures 7 and 8 are schematic diagrams of the three-dimensional structure according to an embodiment of the present invention.

Referring to Figure 7, the connection part of the three-dimensional structure can be folded so that the first part and the second part come into contact with each other based on the folding groove.

For example, after the second three-dimensional structure 200 is separated from the top of the bed, the anchoring layer 232 that contacts the connection part 230 with the top of the bed is in contact with each other based on the connection folding groove 231 of the connection part 230. It can be folded. Accordingly, the fixing layer 232 is bent based on the connection part folding groove 231, and the connection part 230 is folded and overlapped, so that the connection part 230 can have greater resistance to external force. For example, the connection folded structure (Figure 8, 230-1), which is folded and overlapped based on the connection fold groove 231, is inserted into the three-dimensional structure, for example, the depression of Figure 5 (b), to form a three-dimensional structure. It can be fixed more firmly when combined.

The reinforcement layer 233 of the connection part 230 may be formed with a connection protrusion 234 that occupies a portion of the upper area of the reinforcement layer 233.

The connection folding structure (Figure 8, 230-1) is formed by stacking the anchoring layer 232 and the reinforcing layer 233, and the force applied to the connection folding structure (Figure 8, 230-1) is perpendicular to the stacking surface. It is inflicted with Accordingly, since it shows stronger resistance to force applied perpendicularly to the laminated surface, the connection folded structure (FIG. 8, 230-1) can have greater resistance to external force, making it possible to combine three-dimensional structures. It can be advantageous.

Additionally, the first part 210 of the second three-dimensional structure and the second part 220 of the second three-dimensional structure connected to the connecting portion 230 may contact each other. At this time, the anchoring layer in contact with the top of the bed of the first part 210 of the second three-dimensional structure and the anchoring layer in contact with the top of the bed of the second part 220 in the second three-dimensional structure may contact each other.

The connection portion 230 may include one or more through holes 235 penetrating the fixation layer 232 in the connection portion folding groove 231 portion. For example, one or more through holes 235 may be formed in the fixing layer 232 of the connection fold groove 231, like the connection part of a stamp. At this time, the through hole 235 may be formed in either a circular or polygonal shape, but is not limited thereto.

Accordingly, when the connection portion 230 is folded based on the connection portion folding groove 231, the connection portion folding groove 231 can be folded more easily.

The second three-dimensional structure 200 may include protrusions. For example, the first part 210 of the second three-dimensional structure may include the first part protrusion 211, or the second part 220 of the second three-dimensional structure may include the second part protrusion 221, but are not limited thereto. No. At this time, the first part protrusion 211 may be formed by extending the anchoring layer and the reinforcement layer of the first part 210 of the second three-dimensional structure, and the second part protrusion 221 may be formed by extending the second part 220 of the second three-dimensional structure. The anchoring layer and the reinforcing layer may be formed by extending.

The protrusion of the second three-dimensional structure 200 may further have a protrusion that occupies a portion of the upper area of the protrusion. For example, a first part protrusion (not shown) may be formed on the first part protrusion 211 of the second three-dimensional structure 200, and a second part protrusion protrusion 222 may be formed on the second part protrusion 221. ) can be formed.

In addition, the first part protrusion 211 and the second part protrusion 221 are formed at a position where the second three-dimensional structure first part 210 and the second three-dimensional structure second part 220 overlap each other when they come into contact with each other. It can be, but is not limited to this.

Referring to FIG. 8, the three-dimensional structure can be formed by folding the first part and the second part into contact with each other based on the folding groove of the connection part.

For example, the second three-dimensional structure 200 is folded so that the fixing layer in contact with the top of the bed of the connection part is in contact with each other based on the connection folding groove of the connection part, and the second three-dimensional structure first part 210 connected to the connection part is formed. ) and the second three-dimensional structure, the second part 220 may be in contact with each other to form one structure.

At this time, the second three-dimensional structure 200 may have a connection folded structure 230-1 protruding from the outer surface of the second three-dimensional structure 200 formed by folding the connection portion as shown in FIG. 8 (a). For example, the connection folded structure 230-1 may protrude in a rectangular shape perpendicular to the outer surface of the structure of the second three-dimensional structure 200 formed by folding the connection section. Accordingly, the connection folded structure 230-1, in which the connection portion is folded in half and overlapped, is inserted into and joined to another three-dimensional structure, for example, a depression formed in the first three-dimensional structure (FIG. 5 (b)). It can be fixed more firmly when used. At this time, the connection protrusion 234 may be exposed to the outer surface of the connection folded structure 230-1. Accordingly, when the connection folded structure 230-1 is inserted and coupled to a depression formed in another three-dimensional structure, the connection protrusion 234 serves to fix the three-dimensional structure and the three-dimensional structure or the first part and the second part. can do. In addition, the connection protrusion 234 can serve as an insertion guide when inserted into a depression formed in another three-dimensional structure, and the first part 210 and the second second three-dimensional structure are overlapped based on the connection fold groove. The second part 220 of the three-dimensional structure can be prevented from being distorted.

In addition, the second three-dimensional structure 200 is formed by folding the connection portion as shown in Figure 8 (b), and the first part protrusion 211 and the second part protrusion 221 are aligned with each other. They can touch and overlap.

For example, the first part protrusion 211 and the second part protrusion 221 are formed to protrude perpendicularly to the outer surface of the structure of the second three-dimensional structure 200 formed by folding the connection portion, and the first part protrusion (211) and the second part protrusion 221 may be in contact with each other and overlapped. At this time, the shape in which the first part protrusion 211 and the second part protrusion 221 are in contact with each other and overlapped may have the same shape as the connection folded structure (FIG. 8(a), 230-1), but is not limited thereto.

The shape in which the first part protrusion 211 and the second part protrusion 221 are in contact and overlap shows stronger resistance to force applied perpendicular to the stacking surface, so the first part protrusion 211 and the second part protrusion 221 The shape in which (221) is in contact with each other can have greater resistance to external force. Accordingly, it can be advantageous in combining three-dimensional structures.

In addition, the first part protrusion 211 and the second part protrusion 221 can be inserted and combined into a depression formed in another three-dimensional structure, corresponding to the connection folded structure (FIG. 8 (a), 230-1). The first part protrusion 211 and the second part protrusion 221 can be inserted and combined into the depression of the other three-dimensional structure, which is formed in a shape that is.

In addition, when the first part protrusion 211 and the second part protrusion 221 are combined with the depression of the other three-dimensional structure in an overlapping state, the second part 210 and the second three-dimensional structure are The two-dimensional structure second parts 220 may be fixed so that they do not separate from each other while being in contact with each other.

In addition, when the first part protrusion 211 and the second part protrusion 221 are in contact with each other, the first part protrusion 212 and the second part protrusion 222 are connected to the first part protrusion 211 and the second part protrusion 221. It may be exposed to the outer surface of the part protrusion 221. For example, the first part protrusion 211 may be exposed to the outer surface of the first part protrusion 212 formed on the opposite side of the surface where the first part protrusion 211 and the second part protrusion 221 come into contact. . In addition, the second part protrusion 221 may have a second part protrusion 222 formed on a surface opposite to the surface where the first part protrusion 211 and the second part protrusion 221 come into contact with each other, and may be exposed on the outer surface.

Accordingly, when the first part protrusion 211 and the second part protrusion 221 are overlapped and combined with a depression of another three-dimensional structure, the first part protrusion 212 and the second part protrusion 221 The protrusion 222 may serve to fix the three-dimensional structure or the first part and the second part.

Accordingly, one sculpture as shown in Figure 11 (b) can be assembled.

Figure 12 is a flowchart showing the steps of a method for assembling a 3D printer output according to an embodiment of the present invention.

Referring to FIG. 12, the method of assembling a 3D printer output may include a 3D printer output output step (S10), a three-dimensional structure separation step (S20), an inter-part joining step (S30), and a three-dimensional structure combining step (S40). .

The 3D printer output output step (S10) is a step of printing the 3D printer output on the top of the bed. For example, the 3D printer output may be formed by stacking a single layer or multiple layers on the top of the bed, but is not limited thereto. At this time, the 3D printer output may include a plurality of three-dimensional structures.

The three-dimensional structure includes a first part that is three-dimensional, a second part that is three-dimensional and is spaced apart from the first part, a reinforcing layer formed at the bottom of the first part and the second part, and a bottom of the reinforcing layer. It may include a fixation layer formed in contact with the top of the bed, and a connection part formed between the first part and the second part, where the fixation layer is connected and the reinforcement layer is extended. At this time, the connection portion may have a connection fold groove in which no reinforcement layer is formed at the top of the anchorage layer so that the top of the anchorage layer is exposed.

Accordingly, the first part, the second part, and the connection part share the anchoring layer in contact with the top of the bed, and can be stably connected.

Additionally, the three-dimensional structure can be output by forming protrusions or depressions in the first part and the second part. Accordingly, the plurality of three-dimensional structures output in the 3D printer output step (S10) can be output so that they can be combined with each other.

In addition, in the 3D printer output output step (S10), a plurality of the three-dimensional structures are output and formed, and a line output that connects and fixes the plurality of three-dimensional structures is output, so that the three-dimensional structures can be connected and fixed to each other. Accordingly, the plurality of three-dimensional structures can be organized into one 3D printer output to organically manage the plurality of three-dimensional structures.

In addition, when a 3D printer output is formed on the top of the bed, a phenomenon may occur in which the outer portion of the three-dimensional structure is lifted from the bed due to heat contraction. Effect can be given. Accordingly, the shape of the three-dimensional structure can be stably formed.

The three-dimensional structure separation step (S20) is a step of separating the 3D printer output from the top of the bed after the 3D printer output output step (S10) is completed and obtaining individual three-dimensional structures.

For example, it may include separating the plurality of three-dimensional structures and the line output from the top of the bed, and then separating the three-dimensional structure and the line output from the 3D printer output.

Accordingly, it is possible to obtain a plurality of individually separated three-dimensional structures.

In the inter-part bonding step (S30), the connection part of the three-dimensional structure separated in the three-dimensional structure separation step (S20) is folded based on the connection fold groove, so that the fixation layer of the first part and the fixation layer of the second part are formed. This is the stage of joining so that they come into contact with each other. Accordingly, the connecting portion of the three-dimensional structure may be folded and overlapped, and the connecting portion may be folded so that the fixing layers in contact with the upper end of the bed are in contact with each other based on the connecting portion folding groove to form a connecting portion folded structure, and the three-dimensional structure may be formed as described above. The fixation layer of the first part and the fixation layer of the second part may contact each other to form one structure.

The three-dimensional structure combining step (S40) combines a plurality of three-dimensional structures by combining one of the connection folded structure and the protrusion of the three-dimensional structure that completed the inter-part joining step (S30) with the depression of another three-dimensional structure. It's a step.

For example, referring to the above-described FIG. 11 (a), three-dimensional structure-1 (FIG. 11 (a)) including connection folded structure-1 (FIG. 11 (a)), connection folded structure-1 (FIG. 11) Three-dimensional structure-2 (FIG. 11 (a)) and connection folded structure-2 (FIG. 11 (a)) including depression-2 (not shown) and connection folded structure-2 (FIG. 11 (a)) corresponding to (a)) Three-dimensional structure-3 (FIG. 11 (a)) including depression-3 (not shown) and connection fold structure-3 (FIG. 11 (a)) corresponding to 11 (a)), three-dimensional structure-1 ( Connection folding structure-1 (not shown) in the depression-2 (not shown) of three-dimensional structure-2 (FIG. 11 (a)) corresponding to connection folding structure-1 (FIG. 11 (a)) 11 (a)) is inserted and fastened to combine three-dimensional structure-1 (Figure 11 (a)) and three-dimensional structure-2 (Figure 11 (a)), and the connection part of three-dimensional structure-2 (Figure 11 (a)) Insert the connection folded structure-2 (FIG. 11 (a)) into the depression-3 (not shown) of the three-dimensional structure-3 (FIG. 11 (a)) corresponding to the folded structure-2 (FIG. 11 (a)). By fastening, three-dimensional structure-2 (Figure 11 (a)) and three-dimensional structure-3 (Figure 11 (a)) can be assembled to form a single sculpture as shown in Figure 11 (b).

Accordingly, by using the 3D printer output printed according to the step of the 3D printer output assembly method and the three-dimensional structure included in the 3D printer output, damage to the connection portion can be prevented and a plurality of three-dimensional structures can be stably coupled to each other. there is.

In addition, a sculpture can be assembled by simply combining a plurality of three-dimensional structures using the 3D printer output printed according to the step of the 3D printer output assembly method and the three-dimensional structure included in the 3D printer output.
