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: According to an example, a device comprises a sidewall and a base. The sidewall and the base define a chamber for receipt of a volume of build material comprising loose build material and a solid object generated from the build material in an additive manufacturing process. The base is not permeable to build material but permeable to a gas to allow an influx of a gas into the chamber to fluidize loose build material around the solid object in the volume of build material in the chamber to facilitate the removal of the solid object from the loose build material.

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 3D printing module to remove un-solidified build material attached to a 3D printed part is disclosed herein. The 3D printing module comprises a platform within a housing to support a 3D printed part, a vibrating mechanism to vibrate the platform, a cleaning element to apply a cleaning stream within the housing to clean the 3D printed part, and a controller. The controller is to vibrate the platform, generate a cleaning stream in the housing, and to control at least one of the platform and the cleaning element to apply the cleaning stream to different portions of a 3D printed part on the platform.

Abstract: A method of changing the gas content of a device (100) which comprises a first chamber (110). The method comprises: arranging the device in a first configuration, wherein the first chamber has a first internal volume; providing a flow of a first gas to the first chamber so that the gas content of the first chamber is at least partially changed; transitioning the device from the first configuration to a second configuration, wherein the first chamber has a second internal volume which is grater than the first internal volume.

Abstract: In one example, a system for loading build material into a portable build unit having a platform on which objects are printed and a build material supply container next to the platform. The system includes a build material dispenser, a conveyor to move the build unit and/or the dispenser, and a controller operatively connected to the dispenser and the conveyor. The controller is programmed to, with the build unit and the dispenser in a fill position, cause the dispenser to dispense build material into the supply container, cause the conveyor to move the build unit and/or the dispenser to and/or from the fill position, and, while the conveyor moves the build unit and/or the dispenser to and/or from the fill position, cause the dispenser to dispense build material on to the platform.
