  • Publication number: 20220227059
    Abstract: Examples described herein relate to a method of 3D printing. In an example, at least part of a layer of build material is fused. The temperatures of the fused part of the layer are measured at different locations using respective temperature sensors. The temperature sensors are calibrated using the measured temperatures. Heating of additional layers of build material is controlled using the calibrated temperature sensors.

  • Publication number: 20220152933
    Abstract: Object geometry for three-dimensional printers is described in which a first object to be three-dimensionally printed is identified. Geometry data relating to a geometry of all or part of the first object can be obtained. The geometry data can be compared with a predetermined threshold. A determination can be made as to whether the first object may or may not be adversely affected by a post-processing apparatus that will be used to process the object during a post-processing operation based on the comparison.

  • Publication number: 20220143912
    Abstract: A mobile build unit (2) for selectively locating in a build chamber (4) of an additive manufacturing machine (6). The mobile build unit has a build platform (8) to receive build material; and a build unit heater (10) to heat layers of build volume formed on the build platform (8). The build unit heater (10) is movable between a first position in which the build unit heater (10) is stored, and a second position in which the build unit heater (10) is mounted over the build platform (8).

  • Publication number: 20220143915
    Abstract: Object model data modification is described in which object model data defining a first object to be generated by a three-dimensional printer may be obtained. A determination whether the first object is an object that may be adversely affected by a post-processing apparatus during post-processing based on a geometry of the first object to be generated can be made; and if the determination is affirmative, the object model data may be modified by adding a structure to the object model data to create a modified object comprising the first object and the structure, the modified object of a different geometry to the first object so as not to be adversely affected by the post-processing apparatus during the post-processing.

  • Publication number: 20220048113
    Abstract: An example three-dimensional printer includes a print agent distributor to provide a printing agent to a print bed of powdered build material, a heat source to apply heat over the print bed to form a printed part where printing agent is applied, a heat sensor to measure a temperature of the printed part after heat has been applied, and a processor coupled to the heat sensor. The processor is to determine a target power to be applied to the heat source heat a part to a target temperature in a subsequent printing process. The processor is to determine the target power based on the target temperature, a measured first temperature of a first printed part formed when a first power is applied to the heat source and a measured second temperature of a second printed part formed when a second, different power is applied to the heat source.
