Selective Laser Sintering (SLS) is an industrial 3D printing process that is ideal for manufacturing end-use parts. In SLS, a laser selectively sinters polymer powder particles, fusing them together and building a part layer-by-layer. With some of the largest print beds, SLS machines can produce functional plastic parts with isotropic mechanical properties for detailed prototyping or low-volume production of end-use parts. SLS is a cost-efficient production method, which our customers regularly choose for the most complex parts and those requiring extensive customization.

This takes place within the build unit, though HP offers module units for natural cooling, so the build unit can be used for a new print without having to wait for the powder and part to cool.
Once the build unit has cooled down, move it to the processing station and vacuum the unfused powder into a container for later use.
Remove any remaining powder with bead blasting, air blasting or water blasting. You can do this manually or automatically, using a tumbler, ultrasonic cleaner or vibratory finishing machine.
You can choose to dye your printed parts black. The dyeing temperature is about 90°C.
