摘要： A build material container (100) may comprise a container body (102) enclosing a volume to contain a build material (104) for three-dimensional printing. In an example, the container body comprises a sidewall. A compressible wall element (108) may be disposed in the sidewall, wherein compression of the compressible portion wall element reduces the volume of the container. An opening (112) to introduce the build material into the container body may be disposed in an upper region of the sidewall.

摘要： In some examples, a controller is to receive a measurement of an electrical property of an oscillation control system from a sensor, determine, based on the measurement of the electrical property, a frequency of oscillation of a structure vibrated by the oscillation control system in the system, the vibration of the structure to cause passage of a portion of a material through the structure, and estimate a level of a remaining portion of the material at the structure based on the determined frequency of oscillation of the structure.

摘要： An apparatus and method for performing a print operation on a 3D printer (110) are described herein. A 3D printing apparatus comprising a 3D printer (110) is arranged to perform a print operation using build material from a build unit (120) unless a value that identifies a first build material stored in the build unit in a first register, which is set according to an initial build powder fill operation of the build unit (120) by a powder management station, is different from a value in a second register, which is set according to the initial build powder fill operation, or modified in response to, or following, a subsequent opening of the build unit (120).

摘要： Examples of temperature measurement calibration in an additive manufacturing system are described. In one case, a method of calibrating a non-contact temperature measurement device involves applying energy from a radiation source of the additive manufacturing system to heat a reference element. The reference element is thermally coupled to a temperature sensor. A temperature reading from the temperature sensor is compared with data from the non-contact temperature measurement device to calibrate the device.

摘要： In example implementations, an apparatus includes an interface. The interface is to detect a connection to a 3D printer and a connection to a powder supply/post-processing component. The interface may be in communication with a processor. The processor may also be in communication with a timer. The timer is to begin tracking a cooling time when the interface is disconnected from the 3D printer and the processor is to transmit the cooling time to the powder supply/post-processing component when the interface detects the connection to the powder supply/post-processing component.
