When you need heavy-duty, complex plastic parts without any interfering support structures, it is time for selective laser sintering (SLS). The heart of the process is a build chamber completely filled with shielding gas (nitrogen) in which the plastic powder is evenly preheated to around 150 °C. Above it glides a precise 70-watt CO₂ laser (with a fine focus diameter of 0.5 to 0.6 mm) that sweeps across the powder bed at lightning speed, melting the exact contours of your part layer by layer—in wafer-thin layer thicknesses of 0.06 to 0.18 mm, depending on the detail required.

This repeats until the print job is finished or the generous 340 x 340 x 600 mm build volume is filled to the brim.
