This is a one-of-a-kind video that walks through all of the components and theory that go into how to build a Selective Laser Sintering (SLS) 3D Printer. SLS is a much different 3D printing technology than filament- and resin-based 3D printers that have become increasingly common in the household. While not as popular among hobbyists due to cost, SLS printers are very prominent in the industry because they are capable of printing strong and durable parts out of nylon.
SLS printers take powder as raw material and fuse it together with a laser in a defined geometry. After one layer of powder is fused together, another layer is swept over with a blade or roller. This powder handling system and optical setup is very unique to the SLS process and will be explained in detail in this video. The printer built in this video is the Sintratec kit, which, as its name suggests, comes in a DIY format where you have to assemble everything. This is the most affordable SLS printer that you can buy. Is it worth the $6k asking price? Watch the video and leave a comment with your answer.
