METHOD AND DEVICE FOR THE LAYERED CONSTRUCTION OF A SHAPED PART

A method for the layered construction of a shaped body of highly viscous photopolymerizable material, where layers of said shaped body are formed one after the other and one on top of the other, includes forming a material layer of predetermined thickness (a) of the highly viscous photopolymerizable...

Beschreibung
Zusammenfassung:	A method for the layered construction of a shaped body of highly viscous photopolymerizable material, where layers of said shaped body are formed one after the other and one on top of the other, includes forming a material layer of predetermined thickness (a) of the highly viscous photopolymerizable material in a tank, which has a bottom, and lowering the construction platform, or the shaped body at least partially formed on the construction platform, into the material layer so as to cause a layer of the highly viscous photopolymerizable material to form between the construction platform or shaped body and the tank bottom, which layer is cured in a position-selective manner, in particular by irradiation through the tank bottom, to provide the desired shape of the shaped body layer, in which at least one material layer includes a layer thickness variation in the lateral direction.
