Abstract: A method of manufacturing a part formed of metal, a method of determining a ceramic support structure for the metal part, and an un-sintered metal part including the ceramic support. The method of manufacturing the part includes forming a metal part and forming a ceramic support by depositing a ceramic composite material in a pattern to form ceramic print layers. The ceramic support supports a supportable portion of the metal part. The method of determining the ceramic support structure for the metal part includes determining, (i) a composition of a ceramic filament used to produce the ceramic support or (ii) a geometry of an infill of the ceramic support such that the ceramic support has a strength sufficient to support the supportable portion prior to sintering and is deformable to allow the supportable portion to undergo geometric changes during sintering.

Abstract: A 3D printing apparatus and method includes a piezo actuator that reciprocates a tappet. The reciprocation of the tappet generates pressure within a chamber filled with molten print material. The generated pressure causes the molten print material to be extruded through a nozzle coupled to the chamber. The piezo actuator is controlled to switchably provide continuous extrusion of print material or extrusion of discrete droplets of print material.

Abstract: A 3D printing apparatus and method determines features based on design data of an object and at least one classification of a determined feature. The at least one classification includes a classification that the determined feature is a critical feature for the object. At least one print setting for forming the determined feature is modified based on the classification that the determined feature is a critical feature.

Abstract: Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.

Abstract: A method of 3D printing an object includes receiving design information corresponding to an object for which a printed object is to be generated by a 3D printing operation according to a first set of print instructions, generating a plurality of measurement locations, printing successive layers which form the object, measuring the object at the measurement locations to form measurement data, comparing the measurement data with expected measurements of the measurement locations based on the design information, and generating, based on the comparing, deviation information. The measurement locations represent locations of the object to be measured by a measurement device. The deviation information represents deviations between the printed object following completion of the printing, and the object represented by the design information.

Abstract: In additive manufacturing, a composite build material filament and a release material filament are dropped from respective spools to a print head. Each of the composite build material filament and the release material filament includes a metal or ceramic powder plus a binder. On the spools and over the drop height, the filaments are heated to a temperature that flexes the filaments but does not soften them to a breaking point. The drop height is of similar linear scale to the build plate. The materials are debound and sintered.

Abstract: According to various aspects and embodiments described herein, a method for optimizing a three-dimensional (3D) printing process comprises receiving 3D data characterizing a target 3D part, generating a 3D part mesh based on the received 3D data, generating a Signed Distance Field (SDF) based on the 3D part mesh, performing a predictive analysis using the SDF to generate a predicted error field, calculating a correction field based on the predicted error field, applying the correction field to the 3D part mesh to produce a corrected 3D part mesh, creating a corrected 3D print profile using the corrected 3D part mesh, outputting the corrected 3D print profile to a 3D printing device, and printing a corrected 3D part using the 3D printing device and the corrected 3D print profile.
