    Abstract: 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.

    Abstract: A process control method for a 3D-printing process using a 3D printer. The 3D printer has a build platform, a light source, a receiving device for printing material and a control device by which an object can be produced layer-wise or continuously from the printing material. The method includes using a thermal imaging camera, the output signal of which is transmitted to the control device, connected to the 3D printer, The method includes the following steps of illuminating a layer or parts of said layer positionally selectively, detecting the temperature of the layer during the polymerisation using the thermal imaging camera, ending the building process of a layer by ending the illumination, the time of the end of the illumination being established by a predefined temperature Tmax or a predefined change in temperature dT/dt being reached.

    Abstract: The invention relates to a stereolithography device having a replaceable bottle to receive printing material, which bottle may be stored in or on a bottle holder and from which printing material may be withdrawn into the stereolithography device by means of a device-sided holder. A filling level sensor is attached to the bottle holder by which a filling level of the printing material in the bottle can be detected. A mini memory device is associated to the bottle where the stereolithography device stores information regarding the printing material in the bottle, in particular the filling level thereof.
