For reference, the 3D printer described below may manufacture the 3D product 10 using a multi-jet fusion (MJF) method. The multi-jet fusion method exposes the entire layer of building material 112 (also referred to as building material 112 particles) to radiation, but fused and cured selected areas of building material 112 (less than the entire layer in some cases). It can be a layer of a three-dimensional part (or a 3D product or article).

The fusing agent (F) may be selectively deposited into contact with selected areas of the building material 112. The fusing agent F can penetrate into the layer of building material 112 and diffuse onto the outer surface of the building material 112.

This fusing agent (F) can absorb radiation and convert the absorbed radiation into thermal energy. The thermal energy then melts or sinters the building material 112 in contact with the fusing agent F, and thus the building material 112 is melted, bonded, and cured to form a layer of the three-dimensional product 10. . The fusing agent (F) used in multi-jet fusion has a property of absorbing (eg, 80%) in the visible region (400 nm to 780 nm).

In addition, the building material 112 described below is a material particle, and may be a polymer building material 112. Building material 112 may refer to crystalline or semi-crystalline polymer particles or composite particles composed of polymers and ceramics. For reference, the building material 112 may be in a powder form. Examples of semi-crystalline polymers may include semi-crystalline thermoplastic materials with a wide processing window (ie, a temperature range between melting and recrystallization temperatures) of greater than 5°C.

Some specific examples of semi-crystalline thermoplastic materials include polyamide ((PA) (e.g. PA 11/nylon 11, PA 12/nylon 12, PA 6/nylon 6, PA 8/nylon 8, PA 9/nylon 9 , PA 66/nylon 66, PA 612/nylon 612, PA 812/nylon 812, PA 912/nylon 912, etc.).

Other examples of crystalline or semi-crystalline polymers suitable for use as the building material 112 particles include polyethylene, polypropylene, and polysomethylene (ie, polyacetal). Another example of suitable building material 112 particles may include polystyrene, polycarbonate, polyester, polyurethane, other engineering plastics, and mixtures of any two or more of the polymers listed herein.

The building material 112 may have a melting point or softening point in the range of about 50°C to about 400°C. For example, the building material 112 may be polyamide having a melting point of 180°C. The building material 112 particles may be composed of particles of similar size or particles of different sizes. As used herein with respect to the building material 112 particles, the term “size” refers to the diameter of spherical particles or the average diameter of non-spherical particles (ie, the average of a number of diameters across the particles), or the particle It may refer to the volume-weighted average diameter of the distribution. For example, the building material 112 has an average size ranging from 5 μm to about 200 μm.

Hereinafter, a scheduling system for a 3D printer of the present invention will be described with reference to the drawings.

1 is a perspective view for explaining the operation of the 3D printer of the scheduling system of the 3D printer of the present invention, and FIG. 2 is a view for explaining the formation of a layer layer of a 3D product of the scheduling system of the 3D printer of the present invention 3 is a view for explaining 3D products manufactured by the 3D printer of the 3D printer scheduling system of the present invention. And, FIG. 4 is a side view for explaining 3D products manufactured by the 3D printer of the 3D printer scheduling system of the present invention.

First, before describing the 3D printer scheduling system of the present invention, a 3D printer used in the 3D printer scheduling system will be described.

As shown in Fig. 1, the 3D printer includes a material supply unit 110, a material distributor 114, a container in which a working space 104 is formed, and a build platform 102 that moves up and down inside the container, and a printer head. can do.

The container is formed by a fixed wall 105 (shown as a front wall 105a, a side wall 105b, a rear wall 105c, and a side wall 105d), so that a working space 104 may be provided therein.

In addition, a build platform 102 that moves up and down inside the container may be provided inside the container. The build platform 102 may serve as a floor on which a three-dimensional product can be printed (ie, manufactured).

The build platform 102 allows all or part of the three-dimensional product 10 formed by layers of building material 112 and a large amount of building material 112 that are layered into the working space 104 during printing of the three-dimensional product. Can be located. In other words, the manufactured three-dimensional product 10 may be accommodated in the container.

In more detail, when printing of the three-dimensional product 10 is started, the build platform 102 is the working space 104 when the first layer of the building material 112 is stacked and processed on the build platform 102. ) May be located in the upper position 106 toward the top. After the first layer of building material 112 has been treated, the build platform 102 is directed downward when an additional layer of building material 112 from the source 110 is deposited on and processed on the build platform 102. It can be moved to (108) (Z axis in the figure).

For example, even if the build platform 102 moves below the working space 104, all or part of the manufactured 3D product 10 may be supported by unprocessed materials, and accordingly, the 3D printer of the present invention There is an advantage that there is no need for a separate means for supporting the three-dimensional product 10 during manufacture. For reference, the untreated material mentioned herein is a material that is not fused and is a construction material 112 located in a region not corresponding to the three-dimensional product 10, which will be described again later.

The material supply unit 110 may be positioned adjacent to the container, that is, at the side of the container. A building material 112 supplied from a material source may be accommodated inside the container. The building material 112 received in the material supply unit 110 may be applied to the upper surface of the build platform 102 by the material distributor 114.

The material dispenser 114 can move toward the build platform 102 above the material supply 110. For example, as shown, it may move along the Y axis, and the building material 112 may be applied to the upper surface of the build platform 102. In addition, the material dispenser 114 may return to its original position after applying the building material 112 to the build platform 102.

When the building material 112 is applied to the upper surface of the build platform 102 by the material distributor 114, the print head 130 is then operated to apply a fusing agent F and a detailing agent to the applied building material 112. D) can be sprayed to form the shape of the 3D product 10.

For easier explanation, a process in which the shape of the 3D product 10 is manufactured by spraying the fusing agent F and the detailing agent D will be described with reference to FIG. 2.

First, as shown in (A) of Figure 4, the building material 112 may be applied to the build platform 102. Subsequently, as shown in (B) of FIG. 4, the fusing agent (F) and the detailing agent (D) may be sprayed on the upper surface of the applied building material 112. At this time, the fusing agent (F) may be sprayed to the area corresponding to the 3D product 10 and the detailing agent (D) may be sprayed to the area not corresponding to the 3D product 10.

Subsequently, as shown in (C) of FIG. 4, infrared rays may be irradiated to the area where the fusing agent (F) and the detailing agent (D) are sprayed through a fusing lamp or a halogen lamp. The fusing agent (F) absorbs heat when irradiated with infrared rays, and may serve to amplify the temperature of the area where the fusing agent (F) is sprayed. For example, the area in which the fusing agent (F) is sprayed rises to a temperature of 192°C, and accordingly, the building material 112 is fused and cured to form a three-dimensional product 10 as shown in FIG. 4(D). Can be a part of

In addition, the construction material 112 in the area where the detailing agent D is sprayed may maintain its shape without reacting to infrared rays. That is, the construction material 112 in the area where the detailing agent D is sprayed is not fused and hardened, and the initial state of the construction material 112 can be maintained. Therefore, the construction material 112 in the area where the detailing agent D is sprayed protects the shape of the 3D product 10 while maintaining its original state and fills the gaps between the 3D products 10 to prevent the 3D product 10 ) Can play a supporting role.

A 3D printer driven by such a multi-jet fusion method can manufacture a plurality of 3D products 10 having a high speed since the output speed is the same regardless of the quantity or size of the 3D products 10 to be manufactured.

For reference, the fusing agent (F) may include an aqueous or non-aqueous vehicle and a plasmon resonance absorber dispersed therein. The fusing agent (F) may be a color or primer fusing agent (F) comprising CTO nanoparticles as a plasmon resonance absorber, a zwitterionic stabilizer, and an aqueous vehicle.

The fusing agent (F) contains a plasmon resonance absorber. The plasmon resonance absorber allows the fusing agent (F) 26 to absorb radiation (e.g., infrared rays) at a wavelength of 800 nm to 4000 nm, which is constructed by converting sufficient radiation into thermal energy by the fusing agent (F). The material 112 may be allowed to fuse. The plasmon resonance absorber also allows the fusing agent (F) to be transmissive at a wavelength of 400 nm to 780 nm, which can cause the three-dimensional product 10 to be white or slightly colored.

In addition, the detailing agent (D) may be used for thermal management of the building material 112 that is not fused. The detailing agent (D) may be water alone. The detailing agent (D) may contain a surfactant and/or a co-solvent. In one example, the detailing agent (D) is composed of these components and does not contain other components. In another example, the detailing agent (D) may further contain an anti-kogation agent, a biocide, or a combination thereof.

If the 3D printer configured as described above summarizes the operation of manufacturing the 3D product 10, while the 3D printer is started, the build volume in the working space 104 is liquid flux, dissolved energy (radiation) and ultraviolet irradiation. It may include all or part of the three-dimensional product 10 formed by the layer of the building material 112 that is processed through or the like. And, all or part of this three-dimensional product 10 may be supported by the unfused building material 112 within the working space 104. For example, the non-fused building material 112 may support the 3D product 10 by surrounding the 3D product 10 and filling between each of the 3D products 10.

For example, as mentioned above, since all or part of the 3D product 10 manufactured in the working space 104 by the build platform 102 is supported by the untreated powder, the 3D product ( It has the advantage of not requiring a separate means to support 10).

Accordingly, as shown in FIG. 3, a plurality of 3D products 10 manufactured by a 3D printer may be manufactured in batches in a container having a predetermined capacity (ie, a working space 104 having a predetermined capacity).

Hereinafter, a 3D printer scheduling system capable of managing a schedule of a 3D printer will be described using the advantage of being able to collectively manufacture a plurality of 3D products 10 with a container having a predetermined capacity of the present invention.

5 is a block diagram illustrating a 3D printer scheduling system according to an embodiment of the present invention.

Referring to FIG. 5, the scheduling system for a 3D printer of the present invention may include a 3D printer and a control unit.

First, as described above, the 3D printer may be driven in a multi-jet fusion (MULTI JET FUSION) method. That is, since the 3D printer manufactures the 3D product 10 in a multi-jet fusion method, a plurality of 3D products 10 can be manufactured collectively according to the capacity of a predetermined container. For reference, when a 3D printer manufactures a plurality of 3D products 10, when product design information for each of a plurality of product designs is input, a quantity that can be produced collectively may be produced with different designs.

For reference, as shown in FIG. 4, according to the input of the product design information, the first orderer manufactures the 3D product 10 of the quantity corresponding to the first area 10A, and the second orderer manufactures the second order. The 3D product 10 of the quantity corresponding to the area 10B is manufactured, and the third orderer can manufacture the 3D product 10 of the quantity corresponding to the third area 10C. In FIG. 4, all manufactured 3D products have the same volume, but the 3D products 10 manufactured in the first to third regions may have different volumes.

In other words, the maximum quantity of the 3D product 10 that the 3D printer can manufacture may be a quantity corresponding to the capacity of a predetermined container, but the size (ie, volume) of the 3D product 10 to be manufactured is If they are different, the total quantity that can be manufactured may vary according to the volume of each of the 3D products 10.

Hereinafter, for convenience of explanation, the capacity of a container that can be collectively manufactured by the 3D printer is defined as 10, and the container capacity 1 will be described as corresponding to the expected volume for the quantity 1 number of the 3D product 10. . That is, for example, the 3D printer may collectively manufacture 10 3D products 10 having an expected volume of 1 in a container having a capacity of 10.

For example, if a first orderer manufactures five 3D products 10 each having an expected volume of 1, a second orderer may manufacture up to five 3D products 10 each having an expected volume of 1. Alternatively, if the first orderer manufactures two expected volume 3 per unit, the second orderer may manufacture four 3D products 10 having an expected volume 1 per unit.

In summary, the 3D printer can collectively manufacture 3D products 10 in quantities corresponding to the capacity of a predetermined container.

The control unit 400 may receive product design information and production quantity from a plurality of orderers and calculate an individual expected volume for each orderer and a total of the expected volumes. In addition, the control unit 400 may determine the products of the orderer to be collectively manufactured together by comparing the total of the estimated volume obtained by summing the individual estimated volume and the capacity of the container that can be manufactured collectively by the 3D printer.

That is, the control unit 400 compares the total of the expected volumes according to the capacity of containers that can be collectively manufactured by the 3D printer to increase the work efficiency of the 3D printer, and the final design information for driving the 3D printer 300 Can be created.

For reference, the control unit 400 may be provided separately from the 3D printer 300 and implemented as software in a PC or server, and may serve to schedule the 3D printer 300. Further, the control unit 400 provides the scheduled and completed final design information to the 3D printer 300, and the 3D printer 300 can manufacture the 3D product 10 based on the received final design information. have.

Hereinafter, a method in which the control unit 400 schedules the 3D printer 300 will be described in more detail.

The control unit 400 may receive product design information, production quantity, and delivery date of the 3D product 10 from a plurality of orderers through the input unit 410, the measurement unit 420, and the processing unit 430.

First, the input unit 410 may receive design information, production quantity, and delivery date of a 3D product to be produced by the orderer from each of a plurality of orderers. For reference, the design information of the 3D product may include the size and design of the product to be produced by the orderer.

The measurement unit 420 may derive an individual expected volume of each orderer based on the product design information and production quantity input to the input unit 410, and calculate the total of the expected volume obtained by summing the individual expected volumes of a plurality of orderers. have. In addition, the measurement unit 420 may compare the calculated total of the estimated volume with the capacity of the container.

For example, if the product of the first orderer has the predicted volume 2 and the quantity included in the production quantity is 2, the measurement unit 420 may measure the individual predicted volume of the first orderer as 4. Subsequently, if the design information of the product of the second orderer has a volume of 1 and the quantity included in the production quantity is 6, the measurement unit 420 may measure the individual expected volume of the second orderer as 6.

In addition, the measurement unit 420 may measure the sum of the estimated volumes as 10 by summing the individual estimated volumes of the first and second orderers, and compare them with the capacity of the container.

The processing unit 430 may determine 3D products of an orderer to be collectively manufactured by the 3D printer based on a result of comparing the total of the expected volumes compared by the measurement unit 420 and the capacity of the container, and a delivery date.

For example, when the capacity of a container that can be collectively manufactured in a 3D printer is 10 and the total of the expected volumes calculated by the measurement unit 420 is 10, based on the comparison result of the measurement unit 420, the processing unit 430 It is possible to generate final design information by determining the 3D products 10 of the orderer to be collectively manufactured together.

Subsequently, the 3D printer may manufacture the 3D product 10 based on the final design information generated by the processing unit 430.

For example, even if the container has a capacity of 10, when the standard volume for driving the 3D printer 300 is set to 8, when the total of the expected volume reaches 8, the 3D printer 300 ), the final design information that is the basis for driving can be generated.

In one embodiment, if the total of the expected volume measured by the measurement unit 420 is smaller than the capacity of the container, and the earliest delivery deadline among a plurality of orders received from a plurality of orderers has not yet arrived, the control unit 400 is The operation of the 3D printer 300 may be delayed by delaying the generation of final design information until an order is received.

That is, the control unit 400 can efficiently operate the 3D printer by receiving a new order by the earliest delivery date.

The compensation unit 500 may recommend re-input of the delivery deadline to an orderer of a 3D product that exceeds the delivery deadline because the generation of the final design information is delayed.

For example, an orderer who has been advised to re-enter the delivery date may modify the delivery date by extending the delivery date previously input, and at this time, the compensation unit 500 is initially set to the orderer who corrected and entered the delivery date. You can provide a discounted quotation than the previously used quotation.

As another example, the compensation unit 500 may provide a discount quote to an orderer who has entered a delivery date longer than the standard delivery date notified in advance. For example, if the standard delivery date is 10 days and the delivery date input to the control unit 400 is input as 15 days, the control unit 400 may provide a discounted quotation to the corresponding orderer. In other words, if the orderer enters the delivery date longer than the standard delivery date, the period during which new orders can be received becomes longer, making it easier to receive orders from other orderers that fit the container capacity, thereby providing compensation to the corresponding orderer. .

Meanwhile, the control unit 400 may include a cost setting unit 400. The cost setting unit 440 may serve to set an additional cost or premium estimate to a specific orderer based on a preset standard volume.

In one embodiment, when the container capacity is 10 and the standard volume is set to 5, the cost setting unit 400 may set an additional cost or premium estimate to an orderer whose expected volume does not exceed 5 among a plurality of orderers.

Therefore, the scheduling system of the 3D printer of the present invention compares the total of the expected volume with the capacity of the container, and if the earliest delivery deadline has not yet arrived, delays the operation of the 3D printer until a new order is received. In addition, there is an advantage in that the production efficiency of the 3D printer can be increased by smoothly delaying the operation of the 3D printer by providing compensation to the orderer whose delivery period is extended due to the delay in operation of the 3D printer.

In addition, the control unit 400 has the advantage of efficiently managing the recruitment of a plurality of orderers by selectively setting an additional cost to a specific orderer who orders an expected volume less than the standard volume.

Meanwhile, as shown in FIG. 6, a plurality of 3D printers may be provided.

In an embodiment, the input unit 410 of the control unit 400 may receive product design information, production quantity, and delivery date for a plurality of orderers. And, the processing unit 430 is based on the result of comparing the total of the estimated volume calculated based on the design information and the production quantity through the measurement unit 420 and the container capacity of each of the 3D printers, the 3 Dimensional products can be determined on any one of a plurality of 3D printers 300A and 300B.

In one embodiment, when the container capacity of each of the 3D printers 300A and 300B is 10, the expected volume of the first orderer is 5, the expected volume of the second orderer is 6, and the expected volume of the third orderer If is 5, the control unit 400 may generate final design information in order to manufacture 3D products received by the first and third orderers with the first 3D printer 300A.

In addition, the control unit 400 may schedule the 3D products received by the second orderer to be produced through the second printer 300B together with the 3D products received by the new orderer. At this time, if the total of the expected volume corresponding to the container capacity of the second printer 300B is not reached by the delivery date of the second orderer, the control unit 400 recommends the second orderer to re-enter the delivery time and compensates The unit 500 may provide a discount estimate to the second orderer.

In another embodiment, when an order is received from a plurality of orderers, the control unit 400 compares an expected volume for each orderer with a preset reference volume to be manufactured among a plurality of 3D printers 300A and 300B. The dimensional printer 300 can be determined.

For example, the control unit 400 sets a reference volume for determining the 3D printer 300 for manufacturing a plurality of orderers to 4, the estimated volume of the first orderer is 5, and the expected volume of the second orderer A 4, when the expected volume of the third orderer is 1, and the expected volume of the fourth orderer is 2, the orderer's 3D product having an expected volume greater than or equal to the reference volume may be determined to be manufactured by different 3D printers 300. have.

In other words, the control unit 400 is manufactured by the first printer 300A for the 3D product of the first orderer with an expected volume of 5, and the 3D product of the second orderer with the expected volume of 4 on the second printer 300B. You can decide to be. Subsequently, the control unit 400 may determine to manufacture a 3D product of a second orderer and a third orderer whose expected volume is smaller than the reference volume by the first printer 300A.

That is, the total of the expected volume is assigned to the first printer 300A by 8, and the total of the expected volume is assigned to the second printer (300B) by 4, respectively. Production can proceed when a new order is received.

However, if it is determined that the products of the first orderer having the expected volume 5 and the second orderer having the expected volume 4 are manufactured in the first printer 300A, the third orderer and the fourth orderer are in the second printer 300B. Since the total volume of the estimated volume is only 3, the amount of receiving new orders to fill the container's capacity increases, and accordingly, the total of the estimated volume corresponding to the container capacity may not be filled within the delivery deadline.

That is, when an order is received from a plurality of orderers, the 3D printer scheduling system of the present invention compares the expected volume for each orderer with a preset reference volume to be manufactured among a plurality of 3D printers 300A and 300B. By determining the printer 300, it is possible to efficiently operate the production of a 3D printer.

Hereinafter, a method of scheduling a 3D printer capable of collectively manufacturing a plurality of products in a container having a predetermined capacity described above will be described with reference to FIG. 7.

7 is a flowchart illustrating a method of scheduling a 3D printer according to an embodiment of the present invention.

First, a step S100 of receiving product design information, production quantity, and delivery date from a plurality of orderers may be performed. Here, the design information may include the design and size of the 3D product that the orderer intends to manufacture. In addition, the production quantity may mean the quantity the orderer wants to manufacture the product. Lastly, the delivery deadline may mean until the 3D product ordered by the orderer is delivered from the manufacturer of the 3D printer.

After the step (S100) of receiving product design information, production quantity, and delivery date input from multiple orderers (S100), the estimated volume of 3D products to be manufactured based on the design information and production quantity input from a plurality of orderers A step (S200) of calculating the sum of may be performed.

Here, the reason for calculating the total of the estimated volume of the 3D products to be manufactured based on the design information and production quantity input from a plurality of orderers is that the size of the 3D products to be manufactured may vary according to each orderer, and according to the size in advance. This is because the quantity that can be manufactured in a container of a predetermined capacity may fluctuate. That is, in this step, 3D products to be manufactured according to the orderer may be calculated as the expected volume, and the total of the expected volume for each orderer may be derived.

The result of comparing the total of the expected volume and the capacity of the container after the step (S200) of calculating the total of the expected volume of the 3D products to be manufactured based on the design information and production quantity input from a plurality of orderers and the above Based on the delivery deadline, a step (S300) of determining orderer products to be collectively manufactured together may be performed.

For example, if the sum of the expected volumes of 3D products ordered by a plurality of orderers corresponds to the container capacity, it may be determined to manufacture the 3 order products of the corresponding orderer according to the delivery deadline input by the orderers. At this time, the three-dimensional products to be manufactured may be manufactured collectively in accordance with the earliest delivery deadline among the delivery deadlines entered by orderers.

In the step (S300) of determining orderer products to be collectively manufactured together, if the total of the expected volume is smaller than the capacity of the container and the earliest delivery date among the delivery deadlines entered by a plurality of orderers has not yet arrived, a new order is A step (S400) of deferring the operation of the 3D printer until reception may be performed.

For example, in the step (S400) of deferring the operation of the 3D printer, when the capacity of the predetermined container is 10 and the sum of the estimated volumes for a plurality of orderers is 5, the fastest delivery date has not arrived, It is possible to receive new orders from other orderers during the remaining delivery period.

In one embodiment, when the capacity of the predetermined container is 10, and the expected volume for a plurality of orderers is 2, 3, and 1, respectively, 4 out of 10 of the predetermined container capacity is less than the capacity to fill 4 If it is necessary to receive a new order, but the delivery deadline for any one orderer is short and the 3D product of the orderer cannot be manufactured collectively, a step (S500) of recommending the orderer to re-enter the delivery date may be performed. have.

At this time, the orderer who is advised to re-enter the delivery date can enter the corrected input so that the delivery date is extended.

In addition, if the total of the expected volume is less than the capacity of the predetermined container and can be manufactured together, if the orderer of the product that cannot be collectively manufactured due to the delivery date is advised to re-enter the delivery date, a discount estimate is provided to the corresponding orderer ( S600) can be performed.

For example, in the step (S600) of providing a discount estimate to an orderer who has modified the delivery date according to the recommendation, compensation such as providing a discounted estimate for the production cost is provided to the orderer who has modified the delivery date so that the delivery date is extended. can do.

In this case, a step (S700) of differentially applying the discount rate according to the modified delivery deadline step may be performed. For example, an orderer who has modified the delivery deadline may modify the delivery deadline in predetermined steps, and may provide a discount estimate by differentially applying a discount rate according to the stage of the modified delivery deadline.

For example, when the delivery period is extended by 5 days in the first stage and the delivery period is extended by 10 days in the second stage, a 5% discount rate is provided to the orderer who entered stage 1, and 10% to the orderer who entered stage 2 Can provide a discount rate of

Meanwhile, in the step of receiving product design information, production quantity, and delivery date from a plurality of orderers, the step of providing a discount estimate to the orderer whose delivery date is longer than the standard delivery date notified by the orderer is further included. I can.

For example, when manufacturing a 3D product through a 3D printer, if the preset standard delivery deadline is 10, and the orderer enters the delivery deadline exceeding 10 days, that is, 15 days as the delivery deadline, the orderer You can provide a discount quote.

On the other hand, when the expected volume for the design information and production quantity entered by the orderer at the stage of receiving product design information, production quantity, and delivery date from multiple orderers is less than the standard volume notified in advance, the orderer We can provide a premium quote.

For example, when manufacturing a 3D product through a 3D printer, if the preset standard volume is 5, a premium estimate may be provided to an orderer who inputs information corresponding to the expected volume 3 smaller than the standard volume 5.

Although the above has been described with reference to one embodiment of the present invention, those of ordinary skill in the relevant technical field can variously modify the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims. It will be appreciated that it can be modified and changed.
