Description

3D printer device

[0001] The present invention relates to a 3D printer apparatus for performing stereoscopic printing by a three-dimensional printer method, and more particularly, to a 3D printer apparatus for supplying a material for a printer and a Z-axis moving structure for moving up and down, And a 3D printer device.

Recently, we developed a stereoscopic printer which manufactures a certain object directly and called 3D printer. By using it, we can produce a small quantity of goods and produce prototypes for mass production. Actual demand is explosive.

The 3D printer converts the three-dimensional shape modeled by the software that operates the three-dimensional realizable software such as CAD or SolidWorks into slice data that is divided into a plurality of thin cross-sectional layers, , And these are laminated to complete the molding.

Rapid prototyping methods using powder such as gypsum or nylon as a material for rapid prototyping of plate-shaped sheets or rapid prototyping using plastic liquid as a material using liquid (resin) in which photocurable plastic is melted Method, and a molding method using a solid material such as a plastic thread.

In order to complete the above-described molding method, the material is uniformly formed and wound and then unwound and used. In this case, releasing the wound material uniformly plays a very important role.

In order to finish 3D printing on a 3D printer, it is necessary to construct a three-dimensional motion between X-axis, Y-axis, and Z-axis between the table on which the material is formed and the nozzle for spraying the material to be.

In the method for achieving the above-mentioned three-dimensional motion, the nozzle is moved in the X, Y, and Z axes while the table is still stopped. However, since the apparatus for mounting the nozzle is complicated and a lot of weight is added, There was a problem with smoothness and promptness.

Here, we have developed a configuration in which the table moves in the X and Y axes and the nozzle moves in the Z axis, or the nozzle moves in the X and Y axes and the table moves in the Z axis. The technology patent literature is as follows.

In the patent application No. 10-2013-0135068 (Nov. 31, 2013), liquid-based stereolithography of a type of three-dimensional printer molding technique irradiates light to a water tank containing a light hardening resin hardened by light, The photo-curing resin which is hardened according to the shape of the light is laminated when a thin plate-like sheet is produced. In the case of irradiating light, the light is irradiated in a line form instead of a dot or a cross- Dimensional line scan forming device and a molding method using the same. Since the three-dimensional line scan forming device and the molding method using the same are irradiated in a line form when irradiating light, the SLA method irradiates the surface of the photo- The speed of molding is slowed down because it is investigated in the form of dots. Thus, there is a problem that it takes a long time to complete the molding, When the DLP system irradiates light onto the surface of the photocurable resin, it is irradiated in a cross-sectional shape, and the speed at which it is formed is fast. However, the larger the size of the molding, the lower the resolution and precision. It is good, and it can be expressed very precisely, and curves can be expressed much smoother.
