Abstract: Disclosed is a powder build material handling system for a three-dimensional printer. The system comprises a delivery system. The delivery system is to carry powder build material in a flow of gas from a powder build material supply. The delivery system is to filter the flow of gas to separate the powder build material from the flow of gas. The delivery system is to direct the filtered flow of gas to the powder build material supply to form a closed system.

Abstract: It is disclosed a system and a carriage for a 3D printing system comprising: an actuator to move the carriage; a position detection mechanism; a collision detection mechanism; and a controller. The controller to control the movement of the carriage and the controller further comprising: a memory wherein a threshold value and a detection area are stored in, the detection area comprising a set of position values of the carriage; an input to receive a position signal from the position detection mechanism and a detection signal from the collision detection mechanism; and an output to issue an alert signal if the detection signal corresponds to a distance below the threshold value and the position signal is within the detection area

Abstract: 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).
