  • Publication number: 20240100775
    Abstract: Systems, methods, and devices for additive manufacturing are provided. In some embodiments, a method includes: coupling a plurality of build platforms to a carrier; forming a plurality of 3D objects on the plurality of build platforms using an additive manufacturing process, where each build platform receives at least one 3D object thereon; removing the plurality of build platforms from the carrier; performing post-processing of the plurality of 3D objects while the 3D objects remain on the respective build platforms; and separating the plurality of 3D objects from the respective build platforms.

  • Patent number: 11904550
    Abstract: A device for the lithography-based additive manufacturing of three-dimensional structures may comprise a building platform defining a building plane, a light engine designed for the dynamic patterning of light in an exposure field of said light engine, a material transport unit comprising a first drive mechanism for transporting a material layer across the exposure field, a second drive mechanism for causing relative movement of the light engine and the building platform along a displacement path extending parallel to the building plane, a linear encoder for sensing a position and/or a velocity of the light engine relative to the building platform, and/or one or more control units configured to adjust the feeding rate of a pattern data feeder based on the position or the velocity sensed by the linear encoder.

  • Publication number: 20230294354
    Abstract: A device for the lithography-based additive manufacturing of three-dimensional structures on a substrate, comprises a carrier element for carrying a substrate having a curved surface, a light engine designed for the dynamic patterning of light in an exposure field of said light engine, a material transport unit comprising a first drive means for transporting a material layer across the exposure field, second drive means for causing rotational movement of the substrate having the curved surface such as to establish a rolling contact of the curved surface on the material layer in a contact zone, said contact zone being arranged in the exposure field, and first control means configured to control said first and/or second drive means so that said rolling contact of the curved surface on the material layer is essentially slip-free.

  • Patent number: 11426926
    Abstract: A method for the lithography-based additive manufacture of three-dimensional molded bodies, in which a build platform is positioned at a distance from a material support, which is permeable to the radiation of a radiation source at least in some areas, for a material solidifiable by exposure to said radiation, wherein the material support is translationally moved between a first position and a second position, characterized in that material is applied with a defined layer thickness during the movement of the material support from the first position to the second position, after this the applied material, between the build platform and the material support, is location- and/or time-selectively irradiated by the radiation source and solidified, and subsequently material is removed from the material support during the movement of the material support from the second position to the first position.
