The invention provides an internal three-dimensional direct photocuring molding 3D printing device and a control method thereof. The 3D printing device mainly comprises a laser scanning module, a molding platform and a base, wherein the base is used as a body of the whole device; other parts are mounted on the base and mainly comprise a bottom plate, a resin tank, screw rods and optical axes; theresin tank is located in a groove in the middle of the top of the bottom plate and is made of a transparent acrylic material; the screw rods are fixed at the lower left corner and the upper right corner of the bottom plate through bearings; the optical axes are fixed at the lower right corner and the upper left corner of the bottom plate; the molding platform is mounted on the base through the screw rods and the optical axes; the laser scanning module is used as a main module of the device and is mounted on the molding platform; a plurality of laser beams with specific wavelength and power areused for direct scanning, curing and molding in transparent photosensitive resin; the speed of 3D printing is greatly improved; and the efficiency and the stability of the 3D printing device are moresuperior to other 3D printing technologies.
Description
technical field [0001] The present invention relates to the technical field of 3D printing, in particular to an internal three-dimensional direct photocuring 3D printing device and a control method thereof. Background technique [0002] In recent years, the research and application of 3D printer technology has attracted more and more attention from academia and business circles, and it is known as one of the important symbols of the third industrial revolution. Now the traditional 3D printing technology can be roughly divided into different types according to different materials and molding methods: fusion deposition molding (FDM) of plastics, laser sintering or bonded molding of metal powder and plastic powder, photocuring molding of photosensitive resin, and fusion deposition technology. The cost is low, but the speed is very slow and the precision is not high; the laser sintering or bonding of the powder has high precision but the speed is very slow and the cost is high; ...
