Abstract: A 3D printing apparatus and method corrects for skew in the motion components of the apparatus without the use of an independent reference object. A calibration object having features therein or thereon is printed. A user rotates the calibration object by a certain angle after it is printed. The features in/on the calibration object are measured, and an amount of skew is determined based on the measurements. In addition, a 3D printing operation is compensated based on the effects of a coefficient of thermal expansion and/or moisture absorption on dimensional changes.

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 confirms that one or more print parameters was satisfied in the printing of a 3D object. Sensor readings are obtained during the printing of the 3D object. Based on sensor data corresponding to the sensor readings, a confirmation is made as to whether the one or more print parameters was satisfied in the printing of the 3D object.

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: A 3D printing apparatus includes a distance measurement portion that detects the height of a build platen having its height controlled by a displacement control portion. The apparatus detects a Z-scale error by displacing the build platen between at least two different set heights, detecting the heights of the build platen at each set height, and calculating the Z-scale error.

Abstract: A 3D printing apparatus and method determines an optimized reinforcement strategy for improving one or more mechanical properties of a part to be printed. The optimization may include determining reinforcement parameters which yield the highest improvement in such mechanical properties. The reinforcement parameters may include one or more particular portions of the part to print using a reinforced material, a fiber orientation, a density 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.
