Abstract

A photo-curing 3D (three dimensional) printer based on helical scanning and a flexible interface comprises a stepper motor in the middle of the bottom of the printer, the output of the stepper motor is connected with an electric slip ring, a linear feed movement platform is arranged on the electrical slip ring, an integrated LED (light-emitting diode) camera lens is connected to the linear feed movement platform, a film supporting glass holder is arranged outside the integrated LED (light-emitting diode) camera lens, the integrated LED (light-emitting diode) camera lens supports film supporting glass, the film supporting glass is contacted directly with a nonstick film thereon, the nonstick film is fixed on the integrated LED camera lens by a resin groove and a resin groove film fixing cover, the nonstick film supports photosensitive resin, a solidified resin layer is attached onto a lifting head, the lifting head is connected with a lifting system, the LED camera lens is driven to perform Archimedes helical path scanning on the surface of the resin by use of planar helical motion combining rotary motion with linear motion, so that the oscillation can be effectively avoided, the scanning speed and accuracy are improved, the tearing process is more efficient and economic, and the work efficiency of the printer is improved.

Description

technical field [0001] The invention belongs to the technical field of light-curing 3D printing, in particular to a light-curing 3D printer based on helical scanning and a flexible interface. Background technique [0002] Stereo-curing 3D printing is a high-precision additive manufacturing method. Traditional light-curing 3D printers use lasers as the light source system, and focus on a layer of photosensitive resin coated by the coating mechanism through the reflection of the scanning galvanometer to make it solidify and form. However, the cost of this 3D printer is high and the structure is complex. Therefore, a low-cost photocuring 3D printer can use a high-power ultraviolet LED as a light source, an XY linear reciprocating motion table as a scanning mechanism, and a light source at the bottom of the resin tank. The projection method saves the coating structure, thereby reducing the cost. Although these methods are less costly, there are still shortcomings: [0003] 1....
