SLA 3D STEREO LITHOGRAPHY APPARATUS 3D PRINTER

摘要

The present invention provides a stereo lithography apparatus (SLA) 3D printer capable of performing a recoating work at a high speed. According to an embodiment of the present invention, the SLA 3D printer comprises: a main frame; a resin supporting part provided inside the main frame, and supporting a resin; a build platform capable of sliding in a vertical direction along the resin supporting part; an optical part provided on an upper side of the main frame, and irradiating a laser beam to the build platform; a recoater discharging the resin over the build platform while sliding in a horizontal direction along the main frame; and a resin supplying part supplying the resin received from the resin supporting part to the recoater.
