摘要： To provide a method for manufacturing a three-dimensional shaped object in which a three-dimensional shaped object is manufactured by discharging a shaping material from a discharge unit toward a stage to stack a layer, the method for manufacturing a three-dimensional shaped object includes: a first step of generating path data having a plurality of partial paths through which the discharge unit moves while discharging the shaping material; a second step of determining a line width of the shaping material in each of the partial paths and generating line width information for implementing the line width; a third step of generating shaping data including the path data and the line width information; and a fourth step of shaping the three-dimensional shaped object according to the shaping data. In the second step, the line width in a target path that is one of the partial paths is determined in accordance with a distance between a first wall and a second wall separated by the target path. The first wall and the second wall are side edges of the shaping material discharged in the partial path generated before the target path or a contour line of the three-dimensional shaped object.

摘要： A porous apparatus includes a first layer and a second layer. The second layer has a plurality of struts. At least some of the struts define a porous geometry defining a plurality of faces, at least one of the plurality of the faces at least partially confronting the first layer. Each face is bounded by intersecting struts at vertices. Less than all of the vertices of each face of the porous geometry at least partially confronting the first layer are connected by a strut to the first layer. A process of producing the at least partially porous structure includes depositing and scanning metal powder layers. At least some of the scanned metal powder layers form either one or both of a portion of a first section of the structure and a portion of a second section of the structure formed by at least the struts defining the porous geometry.

摘要： Disclosed is a method for providing control data for an additive manufacture device having a first step of accessing model data, and a second step of generating a data model in which a construction material layer region to be solidified during the production of an object section is specified for a construction material layer. The region to be solidified is divided into a first sub-region and a second sub-region, and a respective solidification scan of the region locations to be solidified is specified in a data model. The scan solidifying the construction material, and a repeated scan, is specified at the locations of the second sub-region but not at the locations of the first sub-region. The energy input parameter during the repeat scan is measured such that the temperature of the construction material lies above a melting temperature. The method further includes a third step of providing data models generated in the second step as control data for integrating into a control data set.

摘要： A search apparatus includes a processor and a memory. The processor receives a molding result of a reference sample manufactured by the additive manufacturing apparatus. The processor calculates predicted values from a predictive model. The processor determines whether the evaluation target values are achieved by the measured values. The reference sample has at least three smooth surfaces and a surface having aggregated punched holes formed by straight lines and curved lines that are involved in three types of regions to be set as the conditions.

摘要： A method of measuring spectral emissivity of materials is provided. The method comprises placing material in a controlled chamber and exposing the material to an energy source to heat the material. At least one multi-wavelength pyrometer measures the spectral emissivity of the material produced by heating by the energy source, wherein the multi-wavelength pyrometer is positioned at a distal end of a tube extending from the chamber, wherein the tube provides a sacrificial surface for vapor condensation to prevent the vapor condensation from obscuring a view port used by the pyrometer.
