<p>A powder bed (32) is built up by repeated deposition of a slurry that contains powder. Layers are made by depositing a liquid dispersion of the desired powdered material, which then slip-casts into the forming powder bed to make a new layer (34). The slurry may be deposited in any suitable manner, such as by raster or vector scanning, or by a plurality of simultaneous jets that coalesce before the liquid slip-casts into the bed, or by individual drops, the deposits of which are individually controlled, thereby generating a regular surface for each layer.</p> |
