摘要： The present disclosure relates to a system for performing scanning projection stereolithography. The system uses a light projector which is configured to generate a polymerizing optical signal to initiate polymerization of a photopolymerizable resin or material at a build plane. An optics subsystem collimates and focuses the polymerizing optical signal. The optics subsystem is movable relative to the build plane to optimize focus of the polymerizing optical signal at the build plane. A light scanning subsystem directs the polymerizing optical signal received from the optics subsystem to selected X axis and Y axis locations on the build plane. A positioning subsystem positions the optics subsystem at a selected location relative to the build plane, where the selected location is chosen to optimize focusing of the polymerizing optical signal at a specific, selected X/Y location on the build plane.

摘要： A calibration method of an additive manufacturing apparatus includes an irradiation trace forming step, an imaging step, a specifying step, and a correction step. The irradiation trace forming step scans laser beams with each of a plurality of scanners with respect to a plurality of target positions on a calibration plate installed on a molding region, and forms a plurality of irradiation traces having different shapes for each of the plurality of scanners. The imaging step simultaneously images the plurality of irradiation traces formed with respect to the same target position. The specifying step specifies a plurality of irradiated positions of the laser beam scanned by each of the plurality of scanners. The correction step generates correction data that specifies a deviation amount at any point of a laser coordinate system related to each of the plurality of scanners.

摘要： According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor, cause the processor to access a 3D model of a 3D object to be fabricated and apply a deformation model to the 3D model. In some examples, the processor may generate a modified 3D model that compensates for a determined deformation of the 3D object during a sintering process for the 3D object. In some examples, the deformation model may include a densification component associated with a density of the 3D object and a deformation component associated with mechanical loads on the 3D object. The densification component may have initial state values associated with the density of the 3D object during the sintering process.

摘要： The present disclosure provides a dental orthodontic appliance and a design method and a manufacturing method thereof. The dental orthodontic appliance includes a shell-like body, and the shell-like body is provided with a plurality of cavities for accommodating maxillary teeth, and the shell-like body is further provided with an upper palatal arch that reshapes a form of a dental arch. Two ends of the upper palatal arch are respectively and partially connected to positions of gingival margins or positions adjacent to the gingival margins on ligual sides in posterior regions of left and right sides of the shell-like body. When the shell-like body interacts with teeth, the upper palatal arch can induce buccolingual lateral amplification of maxillary palatal suture bone deposition by means of deformation, and teeth in the posterior regions move laterally buccolingually under an action of the shell-like body.

摘要： This invention relates to a method of evaluating powder for lamination shaping by stable criteria. In this method, it is evaluated whether powder for lamination shaping can be spread into a uniform powder layer in the lamination shaping, wherein the powder is evaluated using, as a flowability of the powder, an adhesive force of the powder calculated from a failure envelope obtained by a shear test. The shear test is conducted by a powder rheometer, and the adhesive force is obtained from the relationship between a normal stress and a shearing stress at the powder rheometer. If the adhesive force is 0.450 kPa or less, the powder is evaluated to be spread into a uniform powder layer in the lamination shaping. Furthermore, if at least one of that the 50% particle size of the powder obtained by a laser diffraction method is 3 to 250 μm and that the apparent density of the powder is 3.5 g/cm3 or more is satisfied, the powder is evaluated to be spread into a uniform powder layer in the lamination shaping.
