摘要： Methods, systems, and apparatus, including medium-encoded computer program products, for designing three dimensional lattice structures include, in one aspect, a method including: creating nodes in a plane normal to an axis in accordance with a spiral, wherein proper subsets of the nodes occur at successive radii positions away from the axis in the plane normal to the axis; repositioning every other one of the proper subsets, from at least a portion of the nodes, in a direction in 3D space along the axis; creating a three dimensional (3D) structure in the 3D space, the 3D structure comprising beams placed between the repositioned and non-repositioned proper subsets; duplicating the 3D structure one or more times to form a lattice in the 3D space; and selecting at least a portion of the lattice for inclusion in a 3D model.

摘要： A method of forming a transparent 3D object and a transparent 3D object formed by the method are provided. A transparent 3D object may be formed as follows. An internal structure of a 3D object is printed using a 3D printer based on a 3D image file having information about an internal region of the 3D object, and a mold, designed to form the 3D object and divided into at least two regions, is printed using the 3D printer based on the 3D image file. Then, the internal structure is combined with an inner region of the mold, and a transparent material is supplied to the mold. After the transparent material hardens, a transparent 3D object is obtained by removing the mold.

摘要： The present invention relates to a multi-stage method for producing one or multiple molded bodies, the method comprising the following steps: a) constructing one or multiple molded bodies in layers by repeatedly applying particulate material by the 3D printing method; b. a presolidification step for achieving a presolidification of the molded body; c. an unpacking step, wherein the unsolidified particulate material is separated from the presolidified molded body; d. a final solidification step, in which the molded body receives its final strength due to the action of thermal energy. The invention also relates to a device which may be used for this method.

摘要： According to an example, an arrangement of parts to be printed in a build envelope of a three dimensional (3D) printer may be determined through identification of a plurality of parts to be printed and generation of a respective virtual bounding box for each of the plurality of parts. In one example, a determination may be made that a total volume occupied by the generated virtual bounding boxes falls below a predetermined threshold of the build envelope volume and an arrangement of the virtual bounding boxes inside the build envelope that results in a total height of the virtual bounding boxes being minimized may be determined, to enhance efficiency in printing of the plurality of parts by the 3D printer.

摘要： A system and method for using multi-axis deposition tool heads on a machine such as a three dimensional fabrication device like a 3D Printer, for novel automation and additive manufacturing techniques which offer increased output product quality and fabrication speed by introducing a novel cartridge and deposition systems and techniques. The system allows a plurality of materials, some reacted or mixed by the device, to be extruded through a deposition head, which may adaptively (and automatically) change shape and lumen size to accommodate different path widths and shapes. The cartridge system may employ pellets which may be comprised of a plurality of materials and/or colors.

摘要： A three-dimensional shaping device includes: a dispensing unit including a nozzle; a stage having a shaping surface on which a shaping material is to be laminated; a position changing unit configured to change a relative position between the nozzle and the stage; a control unit configured to control the position changing unit; and a measurement module used to measure a difference of the nozzle from a reference position in the shaping surface based on a first position of the nozzle in the shaping surface and a second position of the nozzle in the shaping surface. The first position is a position in which the nozzle is assumed to be positioned by the control unit controlling the position changing unit. The second position is a position changed by the control unit controlling the position changing unit.

摘要： Arrangement of the parts, particularly addressing arrangement for 3D fabrication, makes use of spatial frequency domain representations of the parts, such that acceptable (or optionally desirable) relative locations (and optionally orientations) of a part relative to another part or an arrangement of multiple other parts makes use of spatial frequency domain representations of the parts. In some examples, acceptable relative locations may be defined as relative locations that do not result in parts spatially overlapping and/or maintain a desired (e.g., minimum, average, etc.) separation between parts.
