Compared with other 3D printing processes, sla3d printing has the characteristics of wide printing shape, fast forming speed, high precision, and best surface finish. The application fields include almost all industries in the manufacturing field. Has been more and more widely used.

At present, it is mainly applied to the design verification of new product development and the trial production of simulated samples, that is, the development process from product conceptual design → modeling design → structural design → basic function evaluation → simulated prototype trial production. For some products with a plastic structure, small-batch trial production, functional testing, assembly verification, and actual appearance review of some physical aspects can also be carried out. Even small-batch assembly of products can be put on the market first to achieve the purpose of asking for directions.

The application status of sla3d printing in major industries is as follows: Automobiles and motorcycles: Design, modification, assembly test of appearance and interior parts, trial production of engines and cylinder heads. Home appliances: The appearance and structure design of various home appliances, assembly tests and functional verification, market promotion, mold manufacturing. Communication products: product shape and structure design, assembly test, functional verification, mold manufacturing. Aviation and aerospace: direct manufacturing of special parts, trial production of impellers, turbines and blades, trial production and assembly tests of engines. Light industry: design, verification, assembly of various products, market promotion, rapid manufacturing of toys and footwear molds. Medical: Design, trial production and trial of medical devices, physicalization of CT scan information, surgical simulation, and preparation of human bones and joints. National Defense: Design, assembly, trial production of various weapon parts, direct production of special parts, and model production of remote sensing information. Precision casting: The liquid resin used in the light-curing rapid prototyping equipment is a polymer material composed of carbon, hydrogen, oxygen and other elements. It can be completely ablated at a temperature above 700 ℃ without any residual substances. For manufacturing precision casting models, this is a very important performance. At present, it can replace the artificial carving wax process in the jewelry industry, which can greatly improve the molding accuracy and efficiency.
