    摘要： A method for manufacturing a three-dimensional object includes: a first modeling step of extruding a first modeling material to model a raft layer on a modeling surface of a stage; and a second modeling step of extruding a second modeling material and depositing a modeling layer on the raft layer to model an object. The raft layer is separated from the object after the second modeling step is completed. The first modeling step includes at least one of modeling the raft layer by separately modeling a base layer in contact with the modeling surface and a contact layer disposed above the base layer and to come into contact with the object such that at least one of a type of the first modeling material, a depositing pitch, a separation distance in a depositing direction, a modeling pattern, and a condition for layer disposition in a lateral direction is different, and modeling the raft layer by separately modeling a first layer and a second layer arranged in the lateral direction under different modeling conditions.

    摘要： A method for producing a molded product formed of foamable plastics particles using a foaming tool for processing the foamable plastics particles, wherein the molded product includes at least one region that forms at least one portion of a cavity. The method for forming the molded product includes introducing pre-foamed plastics particles into the cavity, and processing the pre-foamed plastics particles into the molded product by expanding the pre-foamed plastics particles such that the pre-foamed plastics particles expand in the cavity thereby forming the molded product. At least one part of a surface structure of the at least one region forming a surface of the at least one portion of the cavity is produced by an additive method. The surface structure includes multiple elevations and depressions in the surface of the foaming tool.

    摘要： Methods, systems, and/or apparatuses for making an object on a bottom-up stereolithography apparatus that includes a light source, a drive assembly, optionally a heater and/or cooler, and a controller. The light source, optional heater and/or cooler, and/or the drive assembly have at least one adjustable parameter that is adjustable by said controller. An example method comprises (a) installing a removable window cassette on said apparatus in a configuration through which said light source projects, said window cassette comprising an optically transparent member having a build surface on which an object can be produced, and with said optically transparent member having at least one thermal profile associated therewith; and then (b) modifying said at least one adjustable parameter by said controller based on said at least one thermal profile of said optically transparent member; and then (c) producing the object on said build surface from a light-polymerizable liquid by bottom-up stereolithography.
