Patent number: 11599028Abstract: Methods and arrangement for clamping substrates to a support using adhesive material area disclosed. The method comprises providing a support comprising a first surface defining a plane; applying adhesive material on at least portions of the first surface; and placing the substrate onto the adhesive material, wherein the adhesive material forms a plurality of support locations supporting the substrate. Preferably the adhesive material is cured at least partly during the application of a substantially uniformly distributed force to the substrate in the direction of the support. The arrangements comprise a support comprising a first surface, for supporting the substrate via adhesive material, whereby the first surface defines a plane. Preferably it also comprises an arrangement for providing electromagnetic radiation, thermal energy, and/or a chemical substance to the adhesive material, and an arrangement for providing a substantially uniformly distributed force to the substrate in the direction of the support.Type: GrantFiled: March 6, 2020Date of Patent: March 7, 2023Assignee: ASML Netherlands B.V.Inventor: Marc Smits

Patent number: 11599033Abstract: Three-dimensional printing methods and systems use a derived geometry and aligns anisotropic inclusions in any orientation at any number of discrete volumetric sections. Structural, thermal, or geometry-based analyses are combined with inclusion alignment computations and print preparation methods and provided to 3D printers to produce composite material parts that meet demanding geometric needs as well as enhanced structural and thermal requirements. In one example, optimal inclusion alignment vectors associated with a section of the object are calculated based on specifications for the object, segmenting a three-dimensional model of the object into layer slices, grouping each section within each layer slice having similar alignment vectors and combining the groupings and generating printing instructions for the object according to the grouped alignment vectors.Type: GrantFiled: January 14, 2021Date of Patent: March 7, 2023Assignee: 3DFortify, Inc.Inventors: Daniel T. Shores, Joshua J. Martin, Randall M. Erb
