Vulcaman from Germany developed a DIY laser sintering (SLS) 3D printer that you can make for some 400 Euro or 450 USD.Technical specifications:
- 1W 445nm laser diode
- 8 x 8 x 8cm build volume
- 36 x 54 x 60cm outer dimensions
- CORE-XY movement
- speed: 60mm/s tested, 300mm/s possible
- costs around 400€
Video of the machine in action:
Since the nylon powder that commercial SLS printers use costs some 200€ per kilogram, developer used much cheaper black powder for powder coating. This gear was printed in black powder coating material at 60mm/s it has dimensions of 3 x 3 x 0,5cm and took one hour to print.
