Because PEEK has a high melting point of about 343 °C, there has been no way to 3D print high-temperature plastics such as PEEK for a long time, especially fused deposition printing. The first thing researchers realized was the use of laser selective sintering technology (SLS), until recently, a company has realized fused deposition 3D printing PEEK(FDM 3D PRINTING) . Laser Selective Sintering 3D Printing Of PEEK. Selective Laser Sintering (SLS) is the selective laser sintering technology. The principle is to lay a layer of PEEK powder material on the worktable in advance. Sintered, and then continuously circulated, forming layer by layer. The picture below is a PEEK part formed Read more
