Wematter Density
Water jet cabinet
For depowdering 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.
Pieces per job | 30 |
---|---|
Depowdering method | Water blasting |
Water tank capacity | 20 liters |
Running time | 20 minutes |
Water pressure | up to 100 bar |

By utilizing an innovative filtering process the water stays clean, the printed parts are powder-free and all the excess powder is gathered in an accessible powder filter inside the chamber.

Frequently asked Questions and answers
Parts printed from powder in an SLS system emerge from the process with a powdery or grainy surface. Depowdering 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 depowdering 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.
