To provide up to The present invention relates to a block stacking 3D printing system and a method of generating design data for 3D printing.

Recently, 3D printing technology is attracting attention as a technology that will cause the third industrial revolution. 3D printing is attracting attention as the core of the paradigm shift in the manufacturing industry through the drastic simplification of the manufacturing process, because anyone who needs digital design drawings and 3D printers can produce the products they need anywhere in the world. 3D printing itself has been used mainly for prototype production at the production site since the late 1980s. However, with the development of material technology, it has been applied to not only plastic but also glass and metal. Product prices, which have reached hundreds of millions of won, have fallen to tens of millions of won, and popularization is on the verge of the launch of millions of won. As individual needs are diversified, personalized products that cannot be produced by the existing standardized mass production process can be directly produced by 3D printer.In the manufacturing industry, trial and error from product planning to prototype implementation are drastically reduced. Innovation is expected to accelerate. Existing FDM (Solid-based, Resin Extrusion), SLS (Powder-based Rapid Prototyping Technology), SLA (Liquid-Based), which categorizes 3D printers by process method (solid, liquid, powder) 3D printing method of a different concept from the photocurable resin molding) and the like will be proposed through the present invention.

At the same time, it is necessary to improve user accessibility of current 3D printing, which can only be used by learning 3D graphics expertise, and to provide a mobile device so that a user can easily design a desired model. Smartphones with touch screens, motion sensors, 10 megapixel camera sensors, full HD (1920x1080) high-definition displays, and 2GHz quad-core processors are rapidly becoming popular. Along with smartphones, mobile devices such as tablets, smart pads, tablet PCs, etc., more than 6 inches have appeared and are rapidly replacing computers. In addition, various games suitable for the mobile device environment have been introduced, and mobile games have been expanded to the vulnerable class, and especially the elderly smartphone users are getting a good response. Unlike a computer game environment, games for mobile devices such as smartphones are configured to be easily enjoyed in the first short time, and second, the game is easy to enter, but is configured to increase the game difficulty as the game progresses. Third, using a touch screen and a motion sensor It is characterized by the ease of operation and the higher the immersion feeling. Currently, 3D printing requires access to high-level 3D graphics technology. It is necessary to introduce and apply the advantages of universal game accessibility, touch and vibration of smartphone game programs to 3D printing.

In addition, 3D printing technology is classified according to whether the material used is a liquid, a solid or a powder, and how the material is formed using the material. So far, about 20 methods are known to be commercially available, but the commonalities are made according to the principle of 'differential' and 'integral', and the 3D printing process is divided into three stages. After designing using a 3D design program on a computer and storing it in a predetermined data form, the 3D printer divides and analyzes the three-dimensional design drawn into thin horizontal layers as if they were 'differentiated', and then analyzed the material in the shape drawn in the design file. Stacked from bottom to top, the three-dimensional model is completed. In other words, it uses both the finely divided fine model and the integral principle of combining the finely divided pieces into the original one. The most common 3D printing methods are known as FDM (resin extrusion), SLA (photocurable resin molding), DLP (digital optical technology), and SLS (powder-based rapid molding technology).

In the FDM (Resin Extrusion) method, a material, such as a solid plastic, that is soluble in heat, is pulled out like a thread and melted and piled up little by little. A small amount of material is sprayed from place to place to form a shape. Although the cost is relatively low, the material can be put in various ways and the model is made to be durable, but the thickness of the material injector makes the layer clearly visible on the surface, the production speed is long, the precision is not very high, and the finished product Because of the rough surface, post-treatment is required.

SLA (Photocurable Resin Molding) is a method of solidifying layer by laser in a tank containing liquid photocurable plastic that reacts to light. It is suitable for making smooth, complex or delicate shapes, but there is a problem that materials are expensive and expensive.

DLP (Digital Optical Technology) is a method of thinly spraying a laser or photo-curable plastic that reacts to strong UV light on a plate to obtain a result. The sprayed liquid is immediately hardened by an ultraviolet lamp on each side of the sprayer. Stack the material by spraying it back onto the layer. The highest level of precision allows for fine expression, but the disadvantage is that it takes time and is expensive. DLP method is advantageous for precision, surface finish and manufacturing speed, but FDM method is advantageous for material strength. In this way, 3D printers produce data by analyzing more than 10,000 pieces of three-dimensionally drawn objects as if they were differentiated horizontally and stacking very thin layers (layers) one by one to complete from the bottom to the top of the object. Just as an inkjet printer combines three inks, red, blue, and yellow to produce a variety of colors, 3D printers stack layers with wider or narrower positions, depending on the design. Three-dimensional printers developed to date can be stacked up to 3cm per hour, and the layer thickness is about 0.01 ~ 0.08 mm, which is thinner than a sheet of paper. The thinner the layer, the finer the object, but because of the stacking method, there is a limit to 100% perfect reproduction of the actual curve.

That is, the solid and liquid and powder based 3D printing methods known to date have fundamental problems such as very slow lamination speed, weak model strength (limited use as a prototype), difficulty in mixing materials and colors, and high level 3D graphic design technology.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention. Prior to this, terms or words used in the present specification and claims should not be construed as being limited to the ordinary or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their own inventions. Based on the principle that it can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

1 is a block diagram of a block stacking 3D printing system according to the present invention.

As shown in FIG. 1, the block stacking 3D printing system according to the present invention includes a 3D printer 100, a terminal and a computer 200, an operation server 300, and a wired / wireless communication network 400.

With reference to Figure 2 will be described in more detail with respect to the 3D printer according to the present invention.

2 is a block diagram of a 3D printer according to the present invention.

As shown in FIG. 2, the 3D printer 100 according to the present invention includes a work table 110, a reel and a tray 120, a block feed feeder 130, a header and a driving device 140, and bonding and fusion means. 150, image processing means 170 and motion control means 180.

The work table 110 is a work space where a designed designed model 190 is made.

The reel and tray 120 store a plurality of blocks stacked at positions designed to form the designed model 190 made in the work table 110.

The reels and tray blocks are stored in the reels and trays 18 according to their size and shape. The reels and tray blocks are horizontally sized like electronic components, such as 0402 (0.4 x 0.2 mm), 0603, 1005, 1608, 2012, etc. To name a few, a block that is too small increases the amount of work and needs to be standardized in various sizes.

For example, if 0505 (0.5 x 0.5 mm) and 0.5 mm in height are used as the basic block size, the large blocks such as 0505, 1005, 1010, 1505, 1510, 1515, 2005, 2010, 2015, 2020 will be If you do, the dimensions do not match when assembled.

The material of the block may be not only plastic, but also metal, glass, and the like, and various colors may be configured. To implement curves and slope sections, the use of ultra-fine blocks can minimize surface roughness.

Alternatively, a quarter-shaped block (height is the same) can be provided depending on the diameter of the circle. For example, it can be standardized to R10 (radius 1.0 mm), R15, R20, R25, R30, and the like. You can also apply special blocks such as rods. Since blocks are stacked according to the minimum size and thickness of the product, the surface is roughened in the curved section and needs post processing.

As a method of fixing the stacked blocks by bonding in a short time, one side of the block is bonded and one side of the reel and the tray are kept in a non-adhesive state to be used. In this case, the blocks are taken from the reels and trays and placed in a specific position for bonding.

In the case of using a UV curable adhesive, a method of irradiating ultraviolet rays to the block bonding surface with a UV LED device may be applied in order to perform the adhesion in a short time.

Alternatively, a method of applying a bonding material to a work section every time a layer of blocks is stacked may be provided. Alternatively, the block model may be stacked and the bonding material may be applied to the whole. Alternatively, when using a plastic material, there is a method of bonding by ultrasonic fusion at the intermediate stage or at the final stage, and the shape of the block is not a simple rectangular parallelepiped, but it is possible to increase the adhesion area by giving irregularities to be bonded to each other like lego. In order to make the model faster, large blocks must be available. Currently, SMT headers can use 55 x 55 mm BGA and a maximum length of 150 mm, so use large blocks in the straight section. In order to display the curved section precisely, a small block and a curved block must be applied, and thus, an ultra-fine cuboid block and a quarter-circle block can be manufactured and used for each radius size as shown in 0402.

In order to display the inclined surface precisely, a rectangular parallelepiped block having one inclined surface (for example, 5 °, 10 °, 15 °, 20 °, etc.) can be manufactured and used.

Stacking blocks in a simple straight form reduces their strength, so they must be stacked in zigzag blocks to increase their strength. In the design program of a mobile device, if a block stacking area is designated, the largest block is automatically selected first, and the blocks are stacked in zigzag to form and use a layer.

Alternatively, in the step of assembling each of the left (X, Y, Z) to which the block should be located using a number of standardized blocks,

As shown in FIG. 10, means for interconnecting blocks (414) (e.g., a conductive adhesive) to form electrical circuits and contacts 417 to conduct electricity to a particular layer; Including a means for attaching an electrical appliance 416, such as an electronic component 415 or a socket, it can also provide a great advantage to proceed with the electrical circuit configuration and electronic component mounting at the same time in the process of building a block model.

For reference, FIG. 10 is a view illustrating a lamination method that combines the formation of an electric circuit by a 3D printer of a block lamination type 3D printing system according to the present invention.

Or, in the layer-specific model design data assembled by matching the coordinates (X, Y, Z) that the blocks should be located using a number of standardized blocks, as shown in FIG. Extracting locations 418 that cannot reach the lower layer and blocks; The dummy block or auxiliary support 419 should be connected to the lower floor so as to stack the blocks at the positions 418 that cannot be reached. In this case, in the step of stacking the dummy blocks 419 to the lower floor so that the blocks can be stacked at the unreachable position 418, the dummy blocks 419 are easily removed after the completion of the model work. Both ends of the can be configured to have a narrow width.

For reference, FIG. 11 is an embodiment of printing a ring by a 3D printer of a block stacking 3D printing system according to the present invention.

Alternatively, when mixing and stacking blocks having different heights, as shown in FIG. 9, a means for raising a layer by first stacking blocks 413 having a low height so that interference does not occur; When the second layer reaches the layer corresponding to the high block 412, the high block 412 may be stacked.

For reference, FIG. 9 is a view illustrating a lamination method by a 3D printer of a block lamination type 3D printing system according to the present invention.

The block supply feeder 130 supplies the blocks of the reel and the tray 120 to the header and the driving device 140.

The header and driving unit 140 stacks a block of the reel or tray 120 supplied from the block supply feeder 130 at a corresponding position of the working model of the work table 110.

In this case, the mossen control unit 180 controls the header and the driving unit 140 to control the stacking of the blocks supplied from the reel or the tray 120.

In addition, the image processing means 160 determines the exact position of the header and the driving device 140 and the working block state through the image processing to clearly extract the position coordinates of the model being worked on the work table 110. do.

The bonding and fusion means 150 is a means for fixing the blocks stacked by the header and the driving device 140 to supply an adhesive or the like.

Meanwhile, in the 3D printer 100, there are three methods of adjusting the height to stack all the blocks on the corresponding layer and to stack the next layer. The first method is to move the left and right of the header and the driving device 140 to the left and right. When the movement is fixed, the work table 110 is moved downward by the next layer thickness to adjust the height of the working model 190. The second method adjusts the height of the header and the driving device 140 when the maximum height of the model 190 is limited to the vertical movement range of the header and the driving device 140. The third method is configured to adjust the height of the working model 190 by moving the work table 110 downward by the thickness of the next layer when the next layer of the block exceeds the vertical movement range of the header and the driving unit 140. can do.

On the other hand, the 3D printer 100, the motion control means 180, the header and the driving device 140, the work table 110 is configured to move and control in the longitudinal direction to produce a long model 190 Can be configured to

On the other hand, while the 3D printer stacking the standardized block as described above solves the disadvantages of the existing 3D printer, the design process can also be converted to the form of assembling the block rather than graphics, the terminal and the computer 200 is a high performance A highly accessible terminal and computer, which can be designed on a mobile device instead of a computer, is sufficient.
