  • Patent number: 11718039
    Abstract: 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.

  • Publication number: 20230152160
    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: 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.

  • Patent number: 11472905
    Abstract: Modelling material which includes (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 soluble in the polymer formed by polymerization of the monomer (a), wherein the solubility of component (c) decreases as the temperature increases, with the result that a phase separation takes place above a particular temperature. The material is suitable in particular for the production of models of dental restorations for investment casting processes.

  • Patent number: 11351730
    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.
