摘要： Modeling material which contains (a) at least one radically polymerizable monomer, (b) at least one initiator for the radical polymerization and (c) at least one inert component. The inert component (c) is selected from phthalates, polyethylene glycols (PEG), polypropylene glycols (PPG), PEG-PPG copolymers, glycerol derivatives, ethoxylated or propoxylated glycerol, ethylenediamine tetrakispropoxylates and ethylenediamine tetrakisethoxylates. The material is suitable in particular for the production of models of dental restorations for investment casting processes.

摘要： A stereolithography apparatus having a build platform and a tray, into which the build platform can be immersed, wherein at the bottom in or on the tray a light-transmissive film is formed or arranged and is elastically deformable, having a light source or energy source underneath the film, the tray can be filled with flowable printing material, a control apparatus controls the movement of the build platform relative to the film and the control apparatus superimposes, during the substantially vertical release movement between a slice of a structure, produced by stereolithography, on the build platform from the film, upon the release movement a substantially horizontal, in particular translational, transverse movement which transverse movement extends at an angle between 60 and 120° relative to the release movement and has alternating, in particular reciprocating, movement directions.
