Selective Laser Sintering (SLS)
| A layer of ceramic powder is deposited on a support, and possibly compacted by a rolling device. A computer-controlled laser beam scans a two-dimensional cross-section of a part, selectively sintering the layer. A new layer of powder is deposited, compacted and sintered. After completion of the part, the unfused or unsintered powder, which helps hold the part during the process, is removed. This technique may allow local composition variations for gradient materials or manufacture of composites.
