Abstract: A method for managing the temperature of three-dimensional object (102) during additive manufacturing includes depositing material on a partial fabrication of the three-dimensional object, determining thermal properties of the three-dimensional object after depositing the material, and controlling cooling of the object according to said thermal properties. In some examples, the determining of the thermal properties includes determining a temperature variation across the object and controlling position-dependent cooling of the object in a feedback arrangement. Resulting uniform temperature of the object under fabrication can improve dimensional accuracy and material properties of the object.

Abstract: An approach to improving optical scanning increases the strength of optical reflection from the build material during fabrication. In some examples, the approach makes use of an additive (or a combination of multiple additives) that increases the received signal strength and/or improves the received signal-to-noise ratio in optical scanning for industrial metrology. Elements not naturally present in the material are introduced in the additives in order to increase fluorescence, scattering or luminescence. Such additives may include one or more of: small molecules, polymers, peptides, proteins, metal or semiconductive nanoparticles, and silicate nanoparticles.

Abstract: A method for determining estimated depth data for an object includes scanning the object to produce scan data corresponding to a surface region of the object using a first scanning process, configuring an artificial neural network with first configuration data corresponding to the first scanning process, and providing the scan data as an input to the configured artificial neural network to yield the estimated depth data as an output, the estimated depth data representing a location of a part of the object in the surface region.

Abstract: A method includes generating correction data for a construction material that is used by an additive-manufacturing machine to manufacture an object. This correction data compensates for an interaction of the construction material with first radiation that has been used to illuminate the construction material.

Abstract: A method and an apparatus are directed to characterizing a continuously moving 3D object via interferometry -based scanning. The method includes repeatedly forming several depth characterizations of the 3D object along respective scan lines of a plurality of scan lines on the surface of the 3D object. During this scanning, the 3D object is undergoing its continuous motion. The method further includes combining the determined depth characterization along the scan lines of the plurality of scan lines to form a depth map representing at least a depth of a portion associated with a location on the surface of the 3D object in the third direction on a grid of locations arranged in the first and second directions. Forming the depth characterizations includes scanning a frequency-dispersed pulsed optical signal in a first direction across the continuously moving 3D object, said 3D object moving in a second direction substantially orthogonal to the first direction. The scanned optical signal forming scan lines on a surface of the 3D object in a third direction substantially orthogonal to the first direction and the second direction.

Abstract: A method for fabricating a 3D object via a printer (125), the method comprising receiving a 3D specification (105) of a first part of the 3D object; using a predistorter (115) to process the 3D specification (105) to produce a modified 3D specification (120) of the first part of the object, wherein the predistorter (115) is configured with configuration data (225) to compensate for at least some characteristics of a printing process; and causing the printer (125) to print the first part of the object (175) according to the printing process based at least in part on the modified 3D specification

Abstract: A manufacturing method includes using an additive manufacturing process to form a first object. The first object includes layers, among which is a first layer that comprises a first material and a second material. The first material surrounds the second material within the first layer. Both materials are solids that transition into liquids at corresponding first and second temperatures, the first temperature being lower than the second temperature. The method includes, after having formed the first object, exposing the first object to a temperature that is between the first temperature and the second temperature such that the first material melts, thereby leaving behind a second object, the second object comprising the second material.

Abstract: A method for additive manufacturing includes forming an object including depositing a first material including a first coloring component and a second material including a second coloring component, wherein both the first material and the second material further include a corresponding fluorescent component, scanning the object, including causing an emission of an optical signal from the object, wherein the emission of the optical signal is caused at least in part by an emission from the fluorescent components interacting with the first coloring component and the second coloring component as it passes from the fluorescent components to the surface of the object, sensing the emission of the optical signal, and determining presence of the first material and the second material based at least in part on the sensed emission of the optical signal.

Abstract: A scanning approach used in the feedback procedure is able to distinguish between different materials, for example, based on spectral properties (e.g., color) of reflectance from a partially fabricated object. Because material layers can be quite thin, and in general the materials are not completely opaque, properties of subsurface layers can greatly affect the reflectance of a thin layer of one material over a thicker section of another material. Detection of locations of thin layers after a material change takes into account the reflectance characteristics of the object before the thin layer was deposited.
