Description

Technical Field

[0001] The utility model relates to the technical field of stereolithography, in particular to a stereolithography device. Background Technique

[0002] Stereolithography, also known as a stereolithography apparatus, is an advanced rapid prototyping process. The stereolithography technology is mainly based on the photopolymerization principle of liquid photosensitive resin. Under the irradiation of a laser with a specific wavelength and intensity, the liquid photosensitive resin can rapidly undergo a photopolymerization reaction, and the molecular weight increases sharply, realizing the transformation from liquid to solid.

[0003] In view of the above and related prior arts, the inventor believes that the following defects often exist: photosensitive resin is generally used in 3D printers, and curing operations are completed by ultraviolet lamps during printing. A shield is used on the printer to protect the entire device. Most shields lack curing ability, and when printing special structures, it is easy to have problems with insufficient curing effect. Therefore, a stereolithography device is proposed for the above problems. Summary of the Utility Model
