摘要： A method of operating a selective deposition based additive manufacturing system capable of producing a three-dimensional (3D) part includes developing a first layer using at least one electrostatography engine, transfusing the first layer on a part build surface using a transfusion assembly to build the 3D part in a layer-by-layer manner on a part build platform such that a portion of the first layer further builds a fiducial structure in a layer-by-layer manner on the part build platform, measuring a height of the fiducial structure, computing an error between the measured height of the fiducial structure and a target height, adjusting a parameter of the at least one electrostatography engine as a function of the error, developing a second layer using the at least one electrostatography engine in accordance with the adjusted parameter, and transfusing the second layer using the transfusion assembly to further build the 3D part.

摘要： 3-D printers include an intermediate transfer surface that transfers a layer of material to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers of the material on the platen. A sensor detects the thickness of the layer on the platen after a fusing station fuses the layer. A feedback loop is electrically connected to the sensor and a development station (that includes a photoreceptor, a charging station providing a static charge to the photoreceptor, a laser device exposing the photoreceptor, and a development device supplying the material to the photoreceptor). The development station adjusts the transfer bias of the development device, based on a layer thickness measurement from the sensor through the feedback loop, to control the thickness of subsequent ones of the layers transferred from the intermediate transfer surface to the freestanding stack on the platen.

摘要： A 3D object according to the invention comprises substrate layers infiltrated by a hardened material. The 3D object is fabricated by a method comprising the following steps: Position powder on all or part of a substrate layer. Repeat this step for the remaining substrate layers. Stack the substrate layers. Transform the powder into a substance that flows and subsequently hardens into the hardened material. The hardened material solidifies in a spatial pattern that infiltrates positive regions in the substrate layers and does not infiltrate negative regions in the substrate layers. In a preferred embodiment, the substrate is carbon fiber and excess substrate is removed by abrasion.

摘要： A method and apparatus is presented. A portion is cut from a thermoplastic sheet of a first thermoplastic material based on a three dimensional model. The portion is secured to a mold. The portion and the mold are heated under vacuum to form a structure. The structure may take the form of a protective covering. In some illustrative examples, the mold may be formed of a second thermoplastic material based on the three dimensional model using additive manufacturing.

摘要： A method for making an object and an apparatus for making the object in accordance with the method is disclosed. A section of the object is formed by irradiating a layer of material with a radiation, the layer of material being disposed on a material receiving surface of a flexible element shaped by a shaping member contacting the flexible element. The radiation passes through the member and the flexible element. The member is tilted to induce a peeling separation of the member from the element.

摘要： A powder bed is filled layer by layer with a powdered build material containing an activatable binder. The binder in each new layer is locally activated according to a computerized three-dimensional model of an object to fabricate, layer by layer, a sinterable net shape of the object within the powder bed. The sinterable net shape can then be removed, debound as appropriate, and sintered into a final part.

摘要： Binder jetting techniques can be used to deposit and bind metallic particles or the like in a net shape for debinding and sintering into a final part. Where support structures are required to mitigate deformation of the object during the debinding and/or sintering, an interface layer may be formed between the support structures and portions of the object in order to avoid bonding of the support structure to the object during sintering.
