Wematter Density
Water jet cleaning cabinet

Post-processing of 3D printed parts
Efficient workflow

Integrated compressed air activated at the touch of a button

Plug in anywhere

Closed system without need for sewer or water connection

Safe and sound

Clean water through an innovative filtering process

Clean your 3D prints in no time

 By using a closed system with recirculating water and a unique filtering system, Wematter provides a totally safe, easy-to-use and powder-free approach to quickly cleaning SLS 3D prints.

By using water that is pressurized up to 100 bar, the Density extracts and cleans the 3D-printed components in seconds. The water binds the powder, thus preventing it from spreading. See how you can save time and money with Wematter in the below example.

Frequently asked Questions and answers

Parts printed from powder in an SLS system emerge from the process with a powdery or grainy surface. Post-processing refines the component’s finish to create the desired structure. Excess powder is removed from the print’s surface and recesses.

Wematter’s Density uses water to clean the prints because the water binds with the dust. This process makes post-processing safer and more efficient.

Different techniques have different results. A common method is blasting the prints with compressed air. The excess powder is collected with a vacuum cleaner. The downside to this method is that it is time-consuming and leads to powder blown everywhere.

Density is a cleaning cabinet developed for finishing SLS prints using water. Tap water is pumped into a pressurized jet sprayed from a nozzle attached to a pistol grip. The spray removes powder from the print, and the excess dust binds with the water and drains through a filter. The filter captures the dust while letting water pass back into the system.

Although the Density is developed for SLS printing, it is used by producers to clean objects constructed with polyjet, FDM, MJF, and other AM techniques.

We build new cabinets to order. The delivery time is currently 4-6 weeks.
