Abstract

The present disclosure relates to a 3D printer having a cooling function. The 3D printer includes: a tank configured to store therein a photocurable liquid resin; a bed configured to support a shapingobject; a bed transfer unit configured to move the bed in a vertical direction; a light projection unit configured to linearly project laser light to the photocurable liquid resin stored in the tankso as to cure the photocurable liquid resin into a shaping object; a light projection unit transfer unit configured to move the light projection unit; a control unit configured to control operations of the light projection unit, the light projection unit transfer unit, and the bed transfer unit; and a cooling unit configured to dissipate heat generated from the light projection unit.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 2018-0001066 filed on January 4, 2018, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to a three-dimensional ("3D") printer using a linear laser source that shapes a three-dimensional object by projecting laser light onto a photocurable liquid resin, and more particularly, to a 3D printer having a cooling function for cooling the linear laser source. Background technique [0004] Generally, in order to manufacture a prototype having a 3D shape, a solid model manufacturing method, a CNC milling-based manufacturing method, and the like are well known. [0005] However, the solid model manufacturing method is performed manually, so that it is difficult to perform precise numerical control and it takes a lot of time to perform the method. Although the CNC mil...
