Description

3D MODELING METHOD FOR 3D PRINTER [0002]

The present invention relates to a three-dimensional modeling method of a 3D printer, and more particularly, to a three-dimensional modeling method of a 3D printer which automatically divides and outputs stereoscopic modeling data which is not dividedly designed in a form that can be assembled according to a specification of a 3D printer, The present invention relates to a three-dimensional modeling method of a 3D printer capable of shortening a design time of a model and enhancing the utilization and diffusion effect of a small 3D printer.

Generally, in order to produce a molded article having a three-dimensional shape, there are a mock up manufacturing method which is manually performed depending on the drawing, and a numerically controlled automatic manufacturing method using a CNC machine tool.

However, since the mock up manufacturing method is based on manual work, it is difficult to form a precise shape and it takes a lot of time. In the CNC machine tool manufacturing method, precise numerical control is possible, but there is a restriction on the shape that can be processed by tool interference .

In recent years, 3D printers have emerged in which product designers or designers use a computer that stores 3D design drawing data designed through a three-dimensional modeling tool to produce molded products in three-dimensional shapes.

The 3D printer uses SLA (StereoLithography Apparatus) which uses the principle that the scanned part is cured by scanning the laser light to the photo-curable resin and the functional polymer or metal powder instead of photo-curing resin in SLA method. (SLS), FDM (Fused Deposition Modeling), DLP (Digital Light) method using the principle of partially curing by irradiating light to the lower part of the storage tank storing the photo- Processing.

Since the previous 3D printer described above can create a three-dimensional model corresponding to the size of a 3D printer, a small-sized 3D printer can only make a small-sized three-dimensional model, which leads to a problem that utilization and diffusion are reduced.

In addition, in order to create a three-dimensional model of a shape desired by the user, a three-dimensional drawing is created using software having a three-dimensional modeling function, or an actual model is scanned and edited.

In this case, when designing a three-dimensional model of a large size, it is necessary to design an entire three-dimensional model, so that it takes a long time to design, and an improvement measure is required.

The above-described technical structure is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.
