Selective Laser Sintering is a rapid prototyping technology with which you can create durable, metal, plastic, or rubber-like parts directly from any 3D CAD model in as little as one day. The data from a 3D CAD file is entered into the Sinterstation. A precise, thin layer of heat fusible powder is deposited across the build platform.
A computer controlled carbon dioxide laser scans a cross section of the 3D solid model. As the laser draws the cross section, the powder contacted by the laser is fused together, without actually melting the powder, forming a thin layer (typical 0.004"). A new layer of powder is deposited and the process of laser sintering and spreading powder is repeated until the 3D object is complete.
