Device for Processing Photopolymerizable Material in Order to Construct a Shaped Body Layer by Layer

摘要

The method for processing photopolymerizable material for the layered construction of a shaped body comprises
a) providing a tank having a bottom transparent at least in some region, in which the photopolymerizable material is contained;b) moving a construction platform to such a height that a layer of the photopolymerizable material with a specified thickness is defined between the lower side of the construction platform or, if already present, the lowermost cured layer of the part of the shaped body formed thereon and the tank bottom;c) exposing the layer from below through the tank bottom by position-specific exposure so as to cure the material layer in the desired shape;d) repeating steps b) and c) until the last layer of the shaped body is formed.;The photopolymerizable material has a viscosity of at least 20 Pa·s at room temperature (20° C.), and the layer of the photopolymerizable material is heated in the tank to a temperature of at least 30° C. so as to lower its viscosity.
