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: A 3D printing apparatus and method prints a partial part, and continues to print the part after the partially-printed part has been rotated. Each partial printing operation may include reinforcement via application of one or more layers of continuous fiber. The rotation and continued printing of the partially-printed part allows for fiber orientation in different orientations for the printed part.

Abstract: Systems and methods of additively manufacturing leak resistant objects are disclosed. Provided herein are methods of forming objects having walls and/or surfaces that are resistant to leaks. Objects disclosed are formed from or manufactured from compositions, including metals, polymers, and combinations thereof. Objects provided herein are made from methods of forming individual shells, forming of series shells, and layer-by-layer forming of objects. Further disclosed are methods of interconnecting shells, layers, and processes for transitioning therebetween the shells and layers.

Abstract: A 3D production apparatus and method that receives a 3D production file, the 3D production file containing at least one positional command defined based on an implicit representation, the at least one positional command including at least one parameter of the implicit representation. At least one tool command is generated based on the parameters of the implicit representation. A position of a tool is controlled based on the generated at least one tool command, to produce at least a portion of a 3D part corresponding to the 3D production file.

Abstract: Techniques for manufacturing optimization using a multi-tenant machine learning platform are disclosed. A method for manufacturing optimization includes: obtaining physical sensor data, by a manufacturing device associated with a tenant of a multi-tenant machine learning platform; determining, by a machine learning spoke system associated with the tenant, a machine learning parameter based on at least the physical sensor data; preventing exposure of the first physical sensor data of the first manufacturing device to any other tenant of the multi-tenant machine learning platform; transmitting the machine learning parameter from the machine learning spoke system to a machine learning hub system of the multi-tenant machine learning platform; and updating, by the machine learning hub system, a multi-tenant machine learning model based at least on the machine learning parameter.

Abstract: A 3D printing apparatus and method that compensates for offset in the deposition of print material as a result of nozzle movement. The compensation may include discretizing a path of travel of a 3D print nozzle into segments, compensating each path segment based on an expected offset of print material deposition, and generating a compensated path of travel. The compensation may apply an inversion of a system model that is based on an expected offset of print material deposition relative to the nozzle path of travel.

Abstract: Methods of reducing warping of a printed part are disclosed. The method includes depositing a raft comprising a first printable material onto a build platen of a three-dimensional printer. The method includes depositing a support material comprising a second printable material onto the raft. The method further includes depositing an anchor comprising one or more anchor shells of the first printable material onto the raft. The anchor is deposited within the support material. The method further includes printing a part made from the first material above the support material. The securing the part to the anchor by depositing one or more skirt shells comprising the first printable material about the periphery of the part and onto the anchor. The anchor has substantially the same shape as the part.
