SLA rapid prototyping 3D printing has the characteristics of various shape, fast forming speed and high precision. Its application fields include almost all industries in the manufacturing field. It has also been more and more widely used in medical, human engineering, cultural relics protection and other industries. At present, it is mainly applied to the design verification of new product development and the trial production of simulated samples, that is, complete the development process from product conceptual design to modeling design ,structural design ,basic function evaluation and simulated sample trial production. Some products with plastic structure can also be trialed in small batch-production, or some physical functional tests, assembly validation, actual appearance effect inspection, or even put into the market in small batches to achieve the purpose of test the market. The main applications of rapid prototyping technology in various industries are as follows:
1.Automobile and motorcycle: design, modification and assembly test of shape and interior accessories, trial production of engine and cylinder head.
2.Household appliances: the shape and structure design of various household appliances, assembly test and functional verification, market publicity, mold manufacturing.
3. Products: product shape and structure design, assembly test, functional verification, die manufacturing.
4.Aerospace and aerospace: direct manufacturing of special parts, trial production of impellers, turbines and blades, trial production and assembly test of engines.
Light industry: design, validation, assembly of various products, market promotion, rapid manufacturing of toys and footwear moulds.
5.Medical treatment: the design, trial production and trial use of medical devices, the materialization of CT scanning information, surgical simulation, and the preparation of human bones and joints.
6. National defense: the design, assembly and trial-manufacture of various weapon parts, the direct production of special parts, and the model production of remote sensing information.
7. Precision casting: Because the liquid resin used in the photo-curing rapid prototyping equipment is a macromolecule material composed of carbon, hydrogen, oxygen and other elements, it can be completely ablated at temperatures above 700 degrees without any residual substances. This is a very important performance for the production of precision casting model by wax-loss method. At present, artificial wax carving process can be replaced in jewelry industry, which can greatly improve the prototyping accuracy and efficiency.
