Abstract:
1. A method for forming a three dimensional sintered body comprising the steps of: a) providing a basic mould having a configuration adapted to the sintered body that is to be produced; b) treating the surface of the basic mould with an adhering layer to facilitate application of a first surface layer of the sintered body; c) applying particles onto the basic mould, to form said first surface layer, wherein at least a portion of the adhering layer melts from the heat supplied by the particles and, before step e), the portion of the adhering layer that melted is frozen again; d) applying at least one more layer of particles on top of said first surface layer; and e) sintering the particles of said first surface layer and said at least one more layer on the basic mould to form the sintered body.
