摘要： A heating device and method for providing temperature control in an additive manufacturing processes. The heating device is positioned circumferentially about a print head and proximate a top layer of a printed object. An area of the top layer of the printed object is heated by directing energy from the heating device to the top layer as material is deposited from the print head onto the printed object. The directed energy applied to the printed object reduces distortion of the printed object caused by temperature gradients and improves the layer-to-layer bonding of the printed object.

摘要： A three-dimensional manufacturing apparatus and a three-dimensional manufacturing method easily adjust a heating quantity per unit area individually for a solidified region and a non-solidified region of a powder material. A layer formation unit forms a layer of a powder material. Light sources and heat scanning units heat the layer by laser beams. The laser beam heats a solidified region in which the powder material has been fused and solidified. The laser beam heats the non-solidified region of the powder material, which is adjacent to the solidified region. The controlling section controls the light sources and the heat scanning units so as to move the laser beams along a boundary between the solidified region and the non-solidified region, and to fuse and solidify a manufacturing region of the layer.

摘要： A method of making an article is disclosed in which a fusible material is fused with an energy beam applied to the fusible material at a build location with a scanning pattern comprising a plurality of parallel lines terminating at the contoured edge. An energy beam is also applied with a vector scanning pattern at the build location along the contoured edge to liquefy and re-solidify material at the build location along the contoured edge. The method also includes controlling vector scanning energy beam intensity, vector scanning energy beam scanning speed, vector scanning energy beam focus depth, or any combination thereof as a function of an angle between the plurality of parallel lines and the vector along the contoured edge.

摘要： A printer fabricates an object from a computerized model using a fused filament fabrication process. The exit of the nozzle may include a number of concentric rings, where each of which may be selectively opened or closed during extrusion to control extrusion properties such as a volume of extrudate or a mixture of material exiting the nozzle.

摘要： A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material such as a bulk metallic glass. A thermal history of the object may be maintained, e.g., on a voxel-by-voxel basis in order to maintain a thermal budget throughout the object suitable for preserving the amorphous, uncrystallized state of the bulk metallic glass, and to provide a record for prospective use and analysis of the object.

摘要： A method of making a part includes creating a computer file defining the part in layers and a model of a body blank to represent a space defined by a cavity in the part. The part is built using an additive manufacturing process. A layer of powdered material is deposited into a powder bed. The powder bed is preheated by applying a first beam current with a first energy. A second beam current with a second energy level greater than the first energy level is applied to a first region of the layer of the powder bed not including a portion of the cavity. A second region of the powdered material is selectively melted. The partially built part and layer of the powdered material are lowered. Steps are repeated for additional layers in accordance with the computer file to create the part.

摘要： A method of manufacturing a permanent magnet comprises a solution heat treatment. The solution heat treatment includes: performing a heat treatment at a temperature TST; placing a cooling member including a first layer and a second layer on the first layer between the heater and the treatment object so that the first layer faces the treatment object; and transferring the treatment object together with the cooling member to the outside of a heating chamber, and cooling the treatment object until a temperature of the treatment object becomes a temperature lower than a temperature TST−200° C. In the step of cooling the treatment object, a cooling rate until the temperature of the treatment object becomes the temperature TST−200° C. is 5° C./s or more.

摘要： A three-dimensional fabricating apparatus includes a processing-space heater, a fabrication unit, a heat generator, a heat radiator, and a heat-transmission switching unit. The processing-space heater heats a processing space. The fabrication unit fabricates a three-dimensional object in the processing space heated to a target temperature. The heat generator generates heat to heat a heating target in a fabrication process of fabricating the three-dimensional object with the fabrication unit. The heat radiator radiates heat in the processing space. The heat-transmission switching unit causes the heat generated in the heat generator to be transmitted to the heat radiator in a preheating process of heating the processing space to the target temperature. The heat-transmission switching unit switches transmission of the heat from the heat generator to the heat radiator so that a transmission efficiency in transmitting the heat to the heat radiator is lower in the fabrication process than in the preheating process.
