摘要： In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes an additive manufacturing device to form a three-dimensional (3D) printed object with regions of differing porosity. The additive manufacturing system also includes a controller to form the 3D printed object. Specifically, by controlling ejection of a first binding agent onto a porous region and a non-porous region of the 3D printed object and controlling ejection of a second binding agent onto the non-porous region of the 3D printed object.

摘要： A method of determining instructions to be executed by a powder bed fusion apparatus, in which an object is built in a layer-by-layer manner by selectively irradiating regions of successively formed powder layers with an energy beam. The method includes determining an exposure parameter for each location within a layer to be irradiated with the energy beam from a primary exposure parameter, the exposure parameters varying with location. An amount each exposure parameter varies from the primary exposure parameter is determined, at least in part, from a geometric quantity of the object derived from the location of the irradiation.

摘要： A porous implant design method includes defining a design volume for a porous implant, a load to be borne by the design volume, and an objective function solution characteristic related to the design volume. Next, the load is divided into a plurality of sub-loads and an optimization procedure is performed: until all sub-loads have been applied, one of the plurality of sub-loads is applied to the material in the design volume, material from the design volume is removed such that remaining material within the design volume is capable of bearing one of the plurality of sub-loads while satisfying the objection function solution characteristic; the remaining material defines a void space without material, the void space is set as a new design volume for any remaining sub-loads, the new design volume is set as being full of material. Then, the remaining material from each cycle of the optimization is combined.

摘要： In an example, mesh model data representing at least a portion of a print job to be generated by an additive manufacturing apparatus by solidifying build material is received at a processor. Using a processor and based on the mesh model data, it is validated whether the three-dimensional print job described by the mesh model data conforms with at least one of material-dependent shape constraints and apparatus-dependent shape constraints of the additive manufacturing apparatus. If the result of the validation is positive, the mesh model data is rendered, using a processor for manufacturing the three-dimensional print job by an additive manufacturing apparatus. If the result of the validation is negative, a predetermined action is performed.

摘要： In accordance with at least one aspect of this disclosure, a method can include selectively sintering at least a portion of a part and one or more indexing features onto a build plate disposed in a build area of a feedstock powder bed, determining an actual orientation of the part and the build plate relative to a recoater prior to recoating, storing the actual orientation of the part and the build plate relative to the recoater, comparing the actual orientation of the part and the build plate relative to the recoater with a predicted orientation, and recoating the build area with feedstock powder if the actual orientation of the part and the build plate relative to the recoater matches the predicted orientation to achieve a predetermined build quality for a respective layer of the part.

摘要： A three-dimensional object may be manufactured using a powder bed fusion additive manufacturing technique. A layer of powder feed material may be distributed over a solid substrate and scanned with a high-energy laser beam to locally melt selective regions of the layer and form a pool of molten feed material. The pool of molten feed material may be exposed to gaseous nitrogen, carbon, or boron to respectively dissolve nitride, carbide, or boride ions into the pool of molten feed material to produce a molten nitrogen, carbon, or boron-containing solution. The molten nitrogen, carbon, or boron-containing solution may cool and solidify into a solid layer of fused nitride, carbide, or boride-containing material.

摘要： An additive manufacturing system may include a stage, a toolhead adjustable relative to the stage, an additive manufacturing unit (AM unit) adjustably connected to the toolhead, a mechanical unit adjustably connected to the toolhead, and a controller operatively connected to the toolhead, the AM unit, and the mechanical unit. The AM unit may be configured to perform an application subprocess of a unified additive-deformation-machining (ADM) process. The mechanical unit may be configured to perform a deformation subprocess of the unified ADM process. The controller may be configured to control the toolhead, the AM unit, and the mechanical unit and to coordinate performance of the application subprocess and the deformation subprocess during the unified ADM process to produce a metal additive manufactured product having at least one of a desired property and a desired characteristic.

摘要： The invention provides a cross-flow separation element comprising a single-piece rigid porous support (2) having within its volume at least one channel (41) for passing a flow of the fluid medium for treatment, which channel presents a flexuous flow volume (V1) defined by sweeping a generator section along a curvilinear path around a reference axis, and in that the reference axis does not intersect said generator section and is contained within the volume of the porous support.
