  • Patent number: 10889054
    Abstract: A sacrificial substrate for use in stereolithography, having a first surface configured to be attached to a build platform, and a second surface of the sacrificial substrate configured to be attached to a photopolymer part. The sacrificial substrate physically separates the build platform and the photopolymer part, and serves as the deposition surface for the photopolymer part in place of the build platform. The sacrificial substrate may be separated from the build platform and then separated from the photopolymer part via pyrolysis, oxidation, or etching to thereby yield the free photopolymer part without subjecting the part to excess physical force or damage.

  • Patent number: 10888924
    Abstract: A powder processing machine includes a work bed, a powder deposition device operable to deposit powder in the work bed, at least one energy beam device operable to emit an energy beam with a variable beam power and direct the energy beam onto the work bed with a variable beam scan rate to melt and fuse regions of the powder, and a controller operable to dynamically control at least one of the beam power or the beam scan rate to change how the powder melts and fuses. The controller is configured to determine whether an instant set of process parameters falls within a defect condition or a non-defect condition and adjust at least one of the beam power or the beam scan rate responsive to the defect condition such that the instant set of process parameters falls within the non-defect condition.

  • Patent number: 10875241
    Abstract: A three-dimensional (3-D) printer includes build and support material development stations positioned to transfer layers of build and support materials to an intermediate transfer surface. The intermediate transfer surface transfers a layer of the build and support materials to a platen each time the platen contacts the intermediate transfer surface. A sensor detects the thickness of the layer on the platen, and a mechanical planer is positioned to contact and level the layer on the platen as the platen moves past the mechanical planer. Additionally, a feedback loop is electrically connected to the sensor and the mechanical planer. The mechanical planer adjusts the amount of the build material and the support material removed from the layer based on the thickness of the layer on the platen, as determined by the sensor.

  • Patent number: 10850444
    Abstract: A three-dimensional fabrication apparatus includes a fabrication chamber, a liquid discharge device, a vibration applicator, and a controller. In the fabrication chamber, powder is layered to form a powder layer, the powder of the powder layer is bonded together in a desired shape to form a layered fabrication object, and another layered fabrication object is laminated on the layered fabrication object. The liquid discharge device discharges a fabrication liquid onto the powder in the fabrication chamber. The vibration applicator applies vibration to the powder layer onto which the fabrication liquid is discharged from the liquid discharge device. The controller controls and drives the vibration applicator to apply vibration to the powder layer when the liquid discharge device discharges the fabrication liquid onto the powder layer to form the layered fabrication object.

  • Patent number: 10843451
    Abstract: A nozzle system and method of manufacturing a nozzle system for use in an additive manufacturing system for fabricating an object is disclosed. The nozzle system includes a monolithic nozzle head designed such that the thermal locking member, neck member, and nozzle member of the nozzle head are manufactured into one component. The nozzle head is made of a material that has a high specific heat capacity but low thermal heat conductivity. The result is a nozzle system design that virtually eliminates heat migration from the nozzle head to the heat sink, and thereby improves the overall quality of polymer filament deposition during printing.

  • Patent number: 10837704
    Abstract: A method for repairing a refractory lining of a metallurgical vessel in the hot state. This repair takes place using a supplying apparatus. In addition, recording of at least the worn regions and monitoring of the repair are carried out by a monitoring device. Before, during and/or after the supplying of material, at least a partial region of the areas of the refractory lining of the vessel or the gunning jet is recorded photographically with visualization of the temperature ranges. This results in an evaluation with regard to different parameters such as properties, layer thickness and/or distribution of the supplied material. It has been demonstrated that visualization of the temperature ranges of the areas to be repaired and of the refractory material during supplying of material enables different parameters to be established very accurately, and as a result, optimal coating of the wall lining can be achieved.
