Description

[0001] Apparatus for introducing 3D printer data [0002]

The present invention relates to a data intermediation apparatus for a 3D printer, and more particularly, to an apparatus for intermediating data for a 3D printer used when a three-dimensional object is printed using a 3D printer.

A 3D printer is a machine that prints out the three-dimensional shape of a real object based on a three-dimensional drawing made by a computer design program. Any product idea can be made from plastic, rubber, metal, ceramics and other materials in an hour to one day.

3D printers are largely classified into a laminate type (additive type or rapid prototyping type) and a cutting type (computer numerically controlled engraving type) according to the method of forming a three dimensional shape. In the laminated type, a three-dimensional shape is formed by stacking layers of powder (gypsum or nylon powder), plastic liquid or plastic yarn in a layer (layer) of 0.01 to 0.08 mm thinner than paper. The thinner the layer is, the more accurate the shape can be obtained and the coloring can proceed at the same time. The cutting type is a method of making a three-dimensional shape by carving out a large lump. Although the finished product is more accurate than the laminated type, it is a drawback that the material is consumed a lot, the inside shape of the cup is difficult to produce, and the coloring work must be done separately.

In the case of stacked or cut 3D printers, 3D objects are created based on data for 3D printers. The data for the 3D printer can be produced using a 3D CAD (computer aided design), a 3D modeling program, a 3D scanner, or the like.

In this way, since data for 3D printer can be produced through 3D CAD, 3D modeling program, or 3D scanner, it is possible to produce only a specialist or a person who learns separately, and it is difficult for ordinary people to obtain data for 3D printer . For example, even if a user tries to make a protective case of his own A-model smartphone using a 3D printer, the data for the 3D printer in which the external dimensions of the A-model smartphone are recorded can not be obtained, There is a problem that the case can not be made. A model To produce data for a 3D printer that enables the manufacture of a protective case for a smartphone, it is necessary to make various modifications after output, or to run a separate 3D CAD or 3D modeling program or 3D scanner, This is because the efforts are very cumbersome in reality.

In order to solve the above problem, the present invention is a method for uploading data (3D drawing) for a 3D printer created by another person and classifying the uploaded data (for example, furniture-desk-model name) You should be able to download it.

To this end, the data intermediation apparatus for a 3D printer of the present invention includes a wired / wireless communication network 400, an upload terminal 100, a download terminal 200, and a mediation server 300.

The wired / wireless communication network 400 uploads the 3D printer data of the upload terminal 100 to the mediation server 300 and downloads the 3D printer data of the mediation server 300 to the download terminal 200. When the wired / wireless communication network 400 is implemented as a wireless communication network, data communication can be performed using a wireless mobile communication network including a base transceiver station (BTS) and a mobile switching center (MSC). For reference, a mobile radio communication network includes a home location register (HLR) and an access gateway (Access Gateway) for enabling wireless packet data transmission and reception, in addition to a base transceiver station (BTS) ), A PDSN (Packet Data Serving Node), and the like. In addition, when the wired / wireless communication network 400 is implemented as a wired communication network, it can be implemented as a network communication network, and data communication can be performed according to an Internet protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol).

The upload terminal 100 uploads and registers the 3D information file including the 3D printer data to the mediating server 300. The upload terminal 100 may be a smart phone. Here, the smart phone is an intelligent terminal that adds a computer support function such as internet communication and information search to a mobile phone, and can install an application desired by the user. The smart phone combines the advantages of a mobile phone and a personal digital assistant (PDA), integrating data communication functions such as schedule management, fax transmission and reception, and Internet access to mobile phone functions. In addition to being able to connect directly to the Internet using wireless Internet, it can be accessed in various ways using various browsing programs. In addition, unlike existing mobile phones, you can install, add, or delete hundreds of different applications (applications) as you like, and you can create your own applications, Can be implemented.

In the embodiment of the present invention, a smart phone will be described as an example of the upload terminal 100 and the download terminal 200. However, not only a smart phone but also a desktop PC, a tablet PC, a slate PC, A PC, a notebook computer, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a navigation, and the like. Of course, it is needless to say that the terminal to which the present invention is applicable is not limited to the above-described type, but may include both terminals capable of communicating with external devices.

The uploading terminal 100 uploads and registers a 3D information file including data for a 3D printer, which is source data for 3D printing, to the mediating server 300, It is a file created and created. As a 3D information file, data for a 3D printer can be included.

Data for a 3D printer is source data for 3D printing, and STL (Standard Triangulated Language) data may be applicable.

2D printers work only on the front and back (x-axis) and left and right (y-axis), but the 3D printer adds the top and bottom (z-axis) motions to produce solid objects based on the input 3D data for the 3D printer. 3D drawing data (STL data) can be produced using a 3D CAD (computer aided design), a 3D modeling program, a 3D scanner, or the like.

For reference, data for the 3D printer can be produced through a 3D CAD (computer aided design), a 3D modeling program, or a 3D scanner. As known in the art, the shape data creation step, shape data editing step, .

The shape data creation step is a step of extracting a three-dimensional shape of the object and creating three-dimensional shape data. 3D shape data is created through a 3D CAD (computer aided design), a 3D modeling program, or a 3D scanner. In order to create three-dimensional shape data, adjustment of the patch surface direction, deletion of unnecessary shells, compensation of gaps, reduction of patches, and smoothing processing of contour shape are performed, Preserves data in STL (Standard Triangulated Language) data format.

Next, the shape data editing step is a step of editing the three-dimensional shape data created by the modeling function. Here, the modeling function is a function provided by a commercially available three-dimensional image CAD software. It is possible to create a cross-section (including a partial cross-section), a plane, a curved surface, a primitive shape, , Adding symbols and letters, and adding marking codes.

Next, in the material type definition step, when a resin is used as a material to be used as a model material, a color, a light transmittance, a high softness, an X-ray permeability, an ultrasonic susceptibility, a susceptibility to scintillation, Can be selected from a variety of resins capable of controlling the parameters of the resin. Further, the support material can be used as a model material for modeling. When two types of resins can be simultaneously injected as a model material, two resin materials of the model material can be selected and the blending ratios thereof (for example, resin A: resin B = 1: 3) can be defined. As described above, the user of the upload terminal 100 can generate 3D printer data through the shape data creation step, the shape data editing step, and the material type definition step.

In addition, as a 3D information file, a 3D printing object produced through 3D printer data is manufactured through a model name of a product to be applied, a type of a product to which a 3D printing object is to be applied, a real photograph of the 3D printing object, And a registered shape image that is a shape image of a product to which a 3D printing object is to be applied.

The model name of the product to be applied to the 3D printing object created through the data for the 3D printer is the model name of the product to which the 3D printing object is to be applied. For example, if the 3D printing object is a protection case for a smartphone and the 3D printing object is to be applied to Apple's iPhone 6, the model name of the product to which the 3D printing object will be applied is 'iPhone 6'.

 For example, when the 3D printing object is a protection case of a smart phone, the type of product to which the 3D printing object is applied is a 'smart phone'.

A real photograph of a 3D printing object is, for example, a photographic image actually taken of a protective case, which is a 3D printing result produced using 3D printer data, when the 3D printing object is a protection case of a smartphone.

For example, when a 3D printing object is a protection case of a smartphone and a product to which a 3D printing object is to be applied is 'iPhone 6', a shape image of a product to be applied to a 3D printing object, The user of the terminal 100 shoots 'iphone 6' and transmits it to the mediation server 300, which stores it as a registered configuration image.

The download terminal 200 downloads 3D printer data selected by the user through the search for 3D printer data registered in the mediation server 300. For example, if the user of the download terminal 200 wishes to directly create a protective case of 'iPhone 6' used by himself / herself by 3D printing, he / she searches through a search window provided by the mediating server 300, Download a 3D information file that can be used to create a protective case.

A search can be performed through a search window in various ways. The user can input and search for a product type to which a 3D printing object is to be applied, or input a product model name to which a 3D printing object is to be applied, search for desired 3D printer data, . Various categories may be provided for each product so that the search can be easily performed.

For security, the 3D printer data downloaded from the download terminal 200 may be encrypted and downloaded. In some cases, a download may be made in the form of a compressed file. Similarly, the upload terminal 100 can also encrypt and upload the data for the 3D printer, or compress and upload the 3D printer data. Also, the registration period can be managed by being validated.

In addition, when the download terminal 200 receives the download data for the 3D printer, it proceeds to make a predetermined payment, and when the payment is completed, the 3D printer data can be downloaded. The payment amount can be distributed to the administrator of the intermediary server 300 and the user of the upload terminal 100 at a predetermined amount of money.

The mediation server 300 registers and stores 3D printer data from the upload terminal 100 and provides a search window for searching 3D printer data to the download terminal 200 so that the 3D printer data And downloads the data to the download terminal 200. The mediation server 300 will be described in detail with reference to Fig.

2 is a configuration block diagram of an intermediary server according to an embodiment of the present invention.

The mediation server may include a mediation server communication unit 310, an upload member database 320, a 3D information file database 330, a search window creation unit 340, and a settlement unit 350. In addition, the 3D printer data recommendation unit 360 may be further included.

The mediation server communication unit 310 supports hardware and software protocols for communicating with the upload terminal 100 and the download terminal 200, respectively. The mediating server communication unit 310 can perform data communication according to an Internet protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol). Therefore, the mediating server communication unit 310 can upload the 3D information file including the data for the 3D printer from the upload terminal 100, and download the 3D printer data to the download terminal 200.

The upload member database 320 is a database (DB) in which personal information of an upload member for uploading a 3D information file including 3D printer data is stored. Personal information may be a name, an address, a contact, an e-mail address, a deposit account, and the like.

The 3D information file database 330 is a database (DB) storing a 3D information file registered in the mediating server 300. The 3D information files uploaded by each upload member are classified and stored.

The upload member database 320 and the 3D information file database 330 may include a hard disk drive, an SSD drive, a flash memory, a Compact Flash card, A module capable of inputting and outputting information such as a card (Secure Digital Card), an SM card (Smart Media Card), an MMC card (Multi-Media Card), or a Memory Stick, Or may be provided in the apparatus.

The search window generating unit 340 generates a search window capable of searching for 3D printer data and provides the search window to the download terminal 200. [ The search window may be provided to the download terminal 200 as a search application form. The search window displays a list of the model names of the products to be applied to the 3D printing object, the types of the products to which the 3D printing object is to be applied, and the real photograph list of the 3D printing object Can be displayed. Accordingly, the user of the download terminal 200 can quickly retrieve the 3D printer data desired by the user using the information provided in the search window.

The settlement unit 350 performs settlement when the download of the data for the 3D printer occurs. When the user of the download terminal 200 selects data for a specific 3D printer through the search, the payment window is popped up and payment is made. Such payment can be made by various methods such as credit card settlement, non-settlement settlement, and the like.

The download downloading unit downloads the 3D printer data selected by the download terminal 200 to the download terminal 200. When the payment for the download cost of the selected 3D printer data is successfully completed, the download transfer unit downloads the selected 3D printer data to the download terminal 200. The download may be transmitted in a streaming manner, at which time it may be compressed or encrypted and transmitted. In addition, data for the 3D printer can be transmitted through the e-mail of the user of the download terminal 200 or the like.

On the other hand, if hundreds of thousands of 3D printer data are registered in the mediation server 300 that mediates 3D printer data, it is difficult for the user of the download terminal 200 to efficiently retrieve the 3D printer data desired by the user. In order to increase the efficiency of such a search, embodiments of the present invention provide a search method for recommending similar products by comparing photographs.

To this end, the download terminal 200 transmits the product photograph image of the product to which the 3D printing object produced through the 3D printer data is applied to the intermediary server 300.

The mediation server 300 extracts the product shape image from the product photograph image received from the download terminal 200 and compares the product shape image with the registered shape image in the 3D information file to calculate the similarity (hereinafter, referred to as 'shape critical similarity') And a 3D printer data recommendation unit 360 for recommending and displaying the 3D printer data allocated to the registered shape image in the search window when the calculated shape critical similarity exceeds the preset shape threshold similarity.

For example, if the 3D printing object of the user of the download terminal 200 is the protection case of the 'iPhone 6', the product photo image of the product to which the 3D printing object is to be applied is a real product photograph of the ' 200 captures a product photograph of 'iPhone 6' and transmits it to the mediation server 300.

The 3D printer data recommendation unit 360 separates the background and the iPhone 6 from the product photograph image of the 'iPhone 6' received from the download terminal 200 and extracts the product shape image of the outline of the iPhone 6. And compares the product shape image of the extracted iPhone 6 with each registered shape image in the 3D information file registered in advance to calculate the shape critical similarity. If the registered shape image is a Samsung Galaxy phone model, the shape threshold similarity will be very low. If the registered shape image is Apple's iPhone, the shape similarity will be high.

The data for the 3D printer is extracted from the 3D information file database 330 on the iPhone in which the calculated shape critical similarity exceeds the preset shape threshold similarity, and is displayed on the search window. Accordingly, the user of the download terminal 200 can retrieve the 3D printer data recommended in the search window within a short period of time.

On the other hand, the data for the 3D printer can each have a copyright as a unique creation of a human being. Therefore, data for other third-party 3D printers that violate the copyright of data for 3D printers already produced by others should not be registered in the intermediary server. For this purpose, the embodiment of the present invention must judge whether the infringement of the copyright is infringed or not and register it. 3, 4, and 5 will be described in detail below.
