    Abstract: A method for operating a system for layered manufacturing of an object on a base element includes A) arranging the base element on a piston plate, B) carrying out a preliminary measurement in the system, wherein a measurement pattern on an upper side of the base element is measured, C) based on data from the preliminary measurement, preparing and carrying out the layered manufacturing of the object, and A′), after the step A) and before the step B), in a treatment region of the base element, roughen a surface of the base element with a working laser in the system. In the step B), the measurement pattern includes a light pattern projected into the roughened treatment region, and/or an edge structure with a plurality of edges. At least a part of the plurality of edges of the edge structure is in the roughened treatment region.

    Abstract: An additive manufacturing condition search device includes a defect database that accumulates a material, shape information, an additive manufacturing condition, monitoring information during modeling, and defect information in association with each other, a first machine learning unit that outputs an additive manufacturing condition corresponding to material information and device information, and outputs a new additive manufacturing condition from a combination of a plurality of the additive manufacturing conditions and the defect information, a specification unit that causes an additive manufacturing apparatus to perform modeling by the additive manufacturing condition, acquires the monitoring information during modeling, and acquires the shape information and the defect information by inspection of a modeled object, a second machine learning unit in which a model trained by using the defect database as train data estimates defect information of the modeled object from the monitoring information and stores the defect information in the defect database, and a determination unit that determines whether or not the defect information of the modeled object has achieved an evaluation target value.

    Abstract: Examples of the present disclosure are directed toward fusing agent compositions. An example fusing agent composition includes a radiation absorber, a co-solvent mixture, and a balance of water. In various examples, the radiation absorber is present in an amount ranging from about 0.005 weight percent (wt %) to about 1.0 wt % of a total weight of the fusing agent composition, wherein the radiation absorber absorbs radiation at a wavelength range within the visible light spectrum.

    Abstract: The present technology comprises methods of manufacturing an orthodontic appliance. For example, a method can include forming an orthodontic appliance in an intermediate configuration by a casting process. The method can further include securing the appliance to a shape forming fixture such that the appliance assumes a desired configuration. The shape forming fixture can comprise a gingiva portion including a surface having a shape corresponding at least in part to a gingiva of a patient and a securing portion carried by the gingiva portion and configured to releasably secure to a portion of the appliance. The method can further include setting a shape of the appliance while the appliance is secured to the shape forming fixture.
