Abstract
Production of a metal or ceramic workpiece, where a liquid suspension consisting of a solvent and metal or ceramic powder particles is poured into a mould and is allowed to dry out. Subsequently the casting is removed from the mould and sintered. The mould (15) is at least partially produced using a regenerative rapid prototyping process. The mould is porous over some sections at least so that after the liquid suspension is poured into the mould the evaporating solvent can escape through it. USE - For production of prototypes. ADVANTAGE - Prototypes with properties similar to those of the corresponding series-produced items can be produce quickly and simply.
