Depowdering Depowdering is the process of removing excess powder material from parts printed using powder-based 3D printing technologies like Selective Laser Sintering (SLS) or Binder Jetting. After printing, the parts are surrounded by loose, unfused powder, which must be carefully extracted to reveal the final object. This step is typically performed using brushes, compressed air, or specialized depowdering stations equipped with vacuum systems. Proper depowdering ensures that fine details are preserved while minimizing material waste, as the recovered powder can often be reused in future prints. It is an essential post-processing step for achieving clean, functional parts, especially in industries like aerospace and healthcare, where precision is critical. |
