Printer is particularly suited for rapid iterative prototyping and/or small batch production. Since SLS is the only 3D printing technology that prints without supports, you can design your parts without limits. As the main material is PA12 Nylon based powder, the printer is primarily designed for functional parts with higher mechanical, thermal or chemical resistance requirements. But printing of soft TPU based parts or experimenting with other materials with melting point under 200°C is also possible.


We’ve done everything we can to make building the printer a fun and enjoyable experience that you can enjoy while understanding the basic principles of how the printer works. I expect you to be able to build it in say 4 to 7 days. No worries if you don’t have any previous experience with building 3D printers or any other complex projects. Our interactive assembly manual will help you to overcome any issues with ease.


Once you build the printer, we believe you will forget that it is a DIY product. Our software solution, which is full of wizards and contextual cues, will give you a quick and easy learning curve leading to successful prints.
