摘要： Process for producing shaped bodies of catalysts, catalyst supports or adsorbents by microextrusion in which a pasty extrusion composition of a shaped body precursor material is extruded through a movable microextrusion nozzle and through movement of the microextrusion nozzle a shaped body precursor is constructed in layerwise fashion and the shaped body precursor is subsequently subjected to a thermal treatment, wherein for construction of each shaped body precursor the pasty extrusion composition is simultaneously extruded through a plurality of microextrusion nozzles.

摘要： Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the disclosed methods comprise selectively depositing a binding material on foam particles in a target area such that the binding material coats at least a portion of defining surfaces of the foam particles with the binding material. The binding material is then cured to affix foam particles in the target area to one another. In various aspects, the disclosed methods can be used to manufacturer articles with sub-regions that differential levels of affixing between the foam particles, and thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

摘要： According to examples, a three-dimensional (3D) fabrication system may include fabrication components and a controller. The controller may control the fabrication components to fabricate parts of a 3D object in a build envelope, the parts to be assembled together to form the object, and in which the parts are fabricated at locations corresponding to relative positions of the parts with respect to each other in the assembled object. The controller may also control the fabrication components to fabricate a cage around the parts in the build envelope.

摘要： An additive manufacturing system includes a powder delivery system, an area scanning laser, a build chamber, and a controller. The powder delivery system provides a predetermined amount of powder material to the build chamber, and includes a material dispenser, a dispensing head, and a scraper. The scanning laser selectively sinters the powder material, and includes a mirror galvanometer for raster scanning. The build chamber has an annular configuration, and includes an inner annular wall that defines a central portion disposed inward of the build chamber. A portion of the delivery system and the laser are located in the central portion. The chamber continuously rotates under the head and under a sintering zone generated by the laser as the delivery system continuously dispenses the material. The laser continuously raster scans the material at the sintering zone in a raster pattern to sinter a layer of material directly to a preceding layer.

摘要： A method of modifying or repairing a fluid conduit assembly includes scanning a sealing feature of a fluid conduit, the sealing feature including an abnormality, creating a 3D model of a sealing member configured to provide a fluid seal with the sealing feature, and utilizing the 3D model to form the sealing member via additive manufacturing. The method may include modifying the sealing feature of the fluid conduit to reduce or remove the abnormality and provide the sealing feature with modified dimensions. Scanning the sealing feature may include determining the modified dimensions of the sealing feature.

摘要： An additive manufacturing system enables continual production of three-dimensional objects without operator intervention. The system is configured to form an object on a planar member, rotate the planar member 180° to enable gravity to move the object from the planar member to an object transport, which carries the object to a receptacle for storage and later processing. The opposite side of the planar member is then available for manufacture of another object and the planar member is again rotated following manufacture of the object so it can be removed and carried to the receptacle. The alternating formation of objects on opposite sides of the planar member continues until a predetermined number of objects has been made. The planar member can include one or more heaters to heat the surface on which an object is formed to facilitate release of the object once the planar member has been rotated.

摘要： Disclosed are a system for and a method of manufacturing a three-dimensional (3D) structure. The method may include injecting a fluid with a first pressure toward a surface of a first output layer to form a softening layer in the first output layer, injecting the fluid with a second pressure toward the softening layer to form an uneven structure in the softening layer, the second pressure being higher than the first pressure, and forming a second output layer on the softening layer with the uneven structure.

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.
