Solution

• Step 1: The powder bin and the build area are first heated just below the melting temperature of TPU and a recoating blade spreads a thin layer of powder over the build platform.
• Step 2: A CO2 laser then scans the contour of the next layer and selectively sinters (fuses together) the particles of the polymer powder. The entire cross-section of the component is scanned, so the part is built solid.
• Step 3: When the layer is complete, the build platform moves downwards and the blade re-coats the surface. The process then repeats until the whole part is complete.
