Current Status Of Rapid Prototyping Technology

- Sep 27, 2018-

The United States is the world's most important producer of RP equipment, and its RP development level and trends basically represent the world's RP development level and trend.

1.Stereoscopic light modeling

3D Systems' SLA27000 model has a scanning speed of 9.52m/s and a layer thickness of up to 0.025mm. AUTOSTRADE (Japan) has developed an RP system using a wavelength laser of about 680 nm as a light source and a visible light resin for this wavelength. Providing photocurable resins include Ciba Corporation of Switzerland, Asahi Denki Corporation of Japan, and Dupont Corporation of the United States.

2. Layered entity manufacturing

Helisys has developed a variety of forming materials for LOM processes that can be used to make molded parts made from sheet metal. The company is also working with Dayton University to develop a LOM process based on ceramic composites. The University of Dundee in Scotland cuts steel sheets using CO2 lasers and uses solder or adhesive to make the shape. Japan's Kira PLT2A4 forming machine uses super-hard tool cutting and selective bonding to make molded parts. Swinburn University of Technology in Australia has developed metal-plastic composites for the LOM process.
