  • Publication number: 20210356310
    Abstract: According to examples, an apparatus may include a first pressure sensor to measure a first pressure level at a first height within a particulate material contained in a container and a second pressure sensor to measure a second pressure level at a second height within the container, in which a gas is to be supplied into the particulate material at a predefined velocity, wherein the first pressure sensor is to measure the first pressure level and the second pressure sensor is to measure the second pressure level while the gas is supplied into the particulate material at the predefined velocity. The apparatus may also include a controller that may determine a pressure gradient from the first pressure level and the second pressure level and calculate a height of the particulate material in the container from the determined pressure gradient.

  • Publication number: 20200139695
    Abstract: According to one example, there is provided an apparatus comprising a supply station to receive a container, and a controller to determine when a build material container is present in the supply station and to cause the supply station to rotate the build material container to transfer build material between the build material container and a build material store, and determine when a post-processing container is inserted into the supply station and to cause the post-processing container to rotate to perform a post-processing operation on a three-dimensionally printed object in the post-processing container.
