Robbert VAN SLUIJS has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Adhesive compositions and their use in 3D printing
    Patent number: 11834590
    Abstract: Adhesive compositions comprising an aqueous dispersion of an acrylic polymer are disclosed, with such compositions having particular applicability in additive manufacturing processes, such as three-dimensional (3D) printing, including Fused Filament Fabrication (FFF). In particular, the compositions address drawbacks associated with an improper degree of adhesion between a thermoplastic build material and build plate, which decrease the quality of printed objects. In representative aqueous dispersions, the solids content of at least about 5 wt. % and also most about 95 wt. % of the acrylic polymer is solubilized, with the balance of this polymer comprising dispersed solid particles.
    Type: Grant
    Filed: December 21, 2018
    Date of Patent: December 5, 2023
    Assignee: STRATASYS, INC.
    Inventors: Wilhelmus Frederikus Zoetelief, Patrick Gerardus Duis, Adrianus Antonius Johannes Van Geel, Danielle Glasbergen-Benning, Rudolfus Antonius Theodorus Maria Van Benthem, Robbert Van Sluijs
  • Compositions and methods for high-temperature jetting of viscous thermosets to create solid articles via additive fabrication
    Patent number: 11578221
    Abstract: Described herein are methods and compositions for forming three-dimensional objects via material jetting processes, the methods including the repeated steps of selectively depositing a liquid thermoset material onto a surface from a nozzle of at least one jetting head in a first specified direction and exposing at least a portion of the liquid thermoset material to a source of actinic radiation in order to form a three-dimensional object from the cured thermoset material, wherein the jetting head is configured to eject droplets of the liquid thermoset material from the nozzle at prescribed elevated operating temperatures, and wherein the liquid thermoset material is chosen so as to possessing prescribed viscosity and rheological characteristics.
