Abstract: In one example, a system for loading a build material powder supply container for 3D printing includes a dispenser to dispense a build material powder into a supply container, a device to measure a density of the build material powder in the supply container, a compactor to compact the build material powder in the supply container, and a controller operatively connected to the measuring device and the compactor. The controller is programmed to control the compactor to compact the build material powder in the supply container until a measured density reaches a threshold density.

Abstract: A computer-implemented method is disclosed. The method comprises receiving object data relating to a three-dimensional object generated or to be generated using an additive manufacturing apparatus, the object data including details of an aperture in a surface of the three-dimensional object; determining, based on the object data, design data for a jig to engage the object and to form a fluid communication channel between the aperture in the surface of the three-dimensional object and an interface of an airflow control mechanism, the airflow control mechanism to cause a flow of air through the aperture; and providing the design data for delivery to an additive manufacturing apparatus to generate the jig. A jig is also disclosed.

Abstract: In one example, a decaking system for 3D printing includes a platform to support multiple green parts in unbound powder surrounding the green parts, a decaking tool to remove unbound powder from around the green parts, a camera to photograph green parts on the platform as unbound powder is removed from around the green parts, and a controller operatively connected to the camera. The controller is programmed to detect a pattern of light intensity in the photographs and, in response to a determination a detected pattern matches a reference pattern, modulate or stop the decaking tool.

Abstract: A method is described in which a digital model of a part to be formed within a build bed is received. The model is rotated within a build volume of the build bed such that the projected area of the part in a plane normal to a flow axis is reduced. The flow axis is an axis along which a flow of gas moves through the build bed during a post-print operation, or the flow axis is defined by a type of post-print operation to be performed on the build bed.

Abstract: According to one aspect, there is provided a method of cleaning a 3D object on a platform. The method comprises generating with a cleaning module a cleaning airflow to remove powder particles from a 3D object and an extraction airflow to extract any removed powder particles, determining a quantity of powder particles in the extraction airflow, and moving the cleaning module relative to the platform based on the determined quantity of powder particles.

Abstract: An additive manufacturing process comprising adding a support to an object model to create a modified object model f an object with a support to be built. The support extends from an object end coupled to the object to a distal end to be engaged with a carrier to support the object. A build model is created by arranging the modified object model within a virtual build volume with the distal end of the support at a defined location within the virtual build volume. Instructions are then provided to build a build cake corresponding to the build model, the build cake comprising the object with support and non-solidified build material.

Abstract: A sensor calibration method is disclosed. The method includes applying thermal energy to a fabrication chamber of an additive manufacturing apparatus to raise a temperature of a surface within the fabrication chamber to a first surface temperature; measuring, using a first sensor to be calibrated, the first surface temperature; measuring, using a second sensor, the first surface temperature; applying thermal energy to the fabrication chamber to raise a temperature of the surface to a second surface temperature; measuring, using the first sensor, the second surface temperature; measuring, using the second sensor, the second surface temperature; determining, using a processor, based on the first and second surface temperatures measured using the first sensor and on the first and second surface temperatures measured using the second sensor, an offset calibration to be applied to measurements obtained using the first sensor; and applying the offset calibration to measurements obtained using the first sensor. An additive manufacturing apparatus and a machine-readable medium are also disclosed.
