Abstract:

3D printing is a rapid prototyping technology which became popular in the approximate last two years. It builds objects through layer-by-layer printing which is based on digital model files. As a new technology in rapid manufacturing, 3D printing is rapidly emerging and will become an important part of the manufacturing industry in the future. This paper introduces the basic principle of 3D printing technology and the current development trend. The printing model is analyzed in detail from four aspects of saving printing materials, improving the strength, increasing the stability and improving the supporting structure, and the related optimization methods are put forward. Structural optimization can reduce the consumption of printed materials, reduce printing costs and eliminate the structural defects of the 3D model. Through the optimization of 3D model, 3D printing technology can continue to make progress.
