Problems solved by technology

[0002] The patent application number is: 201420596495.4, and the patent name is: a 3D printer for high-precision photocuring resin molding, which discloses the following technical scheme: the upper surface of the printing platform is connected to the fixed plate, the fixed plate is connected to the lifting arm, and the lifting arm is fixed on the lifting column Above, the lifting column is set on the lifting base. The defect of this technical solution is that the printing platform is fixed and the angle cannot be adjusted; The base plate of the liquid tank is covered with a layer of high light-transmitting release film. The function of the above scheme is to facilitate the peeling off of the printed solid resin. Due to the existence of the base plate of the liquid tank, the light transmittance will be reduced and the solid-state molding efficiency of the resin will be affected. In addition, long-term storage of high-temperature liquid resin and light exposure will cause the bottom plate to be deformed by heat, and the control error of the lifting base to the position of the liquid storage tank will become larger, resulting in larger printing errors

Abstract

The invention discloses a high-precision 3D printer adopting photo-cured resin forming and belongs to the technical field of 3D printing equipment. The 3D printer comprises a casing, wherein a control display screen and a switch are arranged at the lower part of the casing, an LED light source is arranged at the bottom in the casing, a liquid storage tank is arranged above the LED light source, a printing platform is arranged above the liquid storage tank and glidingly connected with a lifting column through a platform fixing device which is connected with a lifting driving mechanism, and the control display screen is connected with and controls the LED light source and the lifting driving mechanism, through a control system. The printing platform is connected through a universal joint and a fixing mechanism, the angle of the printing platform is adjustable, a printing platform wedge block is mounted in a wedge groove of the fixing mechanism, and the structure is more stable; a release film is used for replacing a bottom plate of the liquid storage tank, accordingly, the transmittance is improved, and curing forming efficiency of liquid resin is increased; the loose release film is tightened by tightening tension screws, and printing errors caused by the loose release film are avoided.
