Control system and control method for novel visible light curing 3D printer

Abstract

The invention relates to the technical field of 3D printing control, and discloses a control system for a novel visible light curing 3D printer. The control system comprises a comprehensive control processor, a servo control combination, a printing driving combination, a light curing control combination and a multi-light source executing combination. The comprehensive control processor is in communication connection to the servo control combination and the light curing control combination, separately, for controlling the servo control combination and the light curing control combination in a linked manner. The invention also discloses a control method for the novel visible light curing 3D printer. The control method comprises the following steps: S1, inputting a printing area and a settingan area threshold value; S2, judging whether the printing area is larger than the area threshold value or not; if not, executing the S3 and if so, executing the S4; S3, turning on a second light source; and S4, turning off a first light source, the light power of which is greater than that of the second light source. According to the invention, the using cost of the light sources is lowered, theprinting precision and speed are improved, and the working reliability and stability of the light curing 3D printer are improved, too.

Description

technical field [0001] The invention relates to the technical field of 3D printing control, in particular to a control system and method for a novel visible light curing 3D printer. Background technique [0002] SLA is the abbreviation of Stereo Lithography Apparatus, that is, stereolithography. SLA 3D printing rapid prototyping technology is a technology based on digital models, using liquid photosensitive resin as material, and constructing objects by layer-by-layer printing. The molding principle is: using liquid photosensitive resin as the processing material, the computer controls the ultraviolet laser beam to scan the photosensitive resin layer by layer according to the layered cross-section information of the processed part, so that it can undergo photopolymerization, and each time it is cured to form a thin layer of the part. Cross-section; after each layer is cured, the working platform moves a height of layer thickness, and then coats a new layer of liquid resin o...
