  • Patent number: 11840018
    Abstract: The present disclosure relates to a method for forming a three dimensional (3D) component from a photopolymer resin. The method may involve generating a first optical beam at a first wavelength, with the first optical beam causing polymerization of a photopolymerizable resist. A second optical beam is generated at a second wavelength, different from the first wavelength, which inhibits polymerization of the photopolymerizable resist. A device is used to receive the first and second optical beams and to generate therefrom corresponding separate first and second light patterns, respectively, where the first light pattern forms a first image on the photopolymerizable resist to cause polymerization of a first portion of the photopolymerizable resist, while the second light pattern forms a second image on the photopolymerizable resist and inhibits polymerization of a second portion of the photopolymerizable resist.

  • Patent number: 11840014
    Abstract: Methods, particularly automated methods, are provided, as well as 3D-printed composite and hollow objects and 3D-printing systems for printing them. Methods comprise deriving a central line of a hollow 3D object model, calculating reference point(s) and/or line(s) along an inner surface of the hollow 3D object model, and filling the hollow 3D object model with material that comprises a thread defined with respect to the central line and the reference point(s) and/or line(s) and with filling material surrounding the thread. The support construction thus formed may be removed from the 3D object by pulling on the thread, extracting it and the surrounding support filling from the hollow object, thus enabling 3D-printing of convoluted or elongated hollow objects and objects with narrow openings. The parameters of the thread, such as type of curve and thickness, are selected to ensure thread extraction without risk of tearing or knotting the thread.
