Abstract: In one example, an article for distributing powder includes a plate having holes therein through which a powder may pass from a first side of the plate to a second side of the plate opposite the first side and multiple ramps each intersecting the plate at one or multiple holes and sloping away from the first side of the plate in a first direction at an angle less than 90°.

Abstract: In example implementations, an apparatus includes a storage unit, an auger screw, a housing enclosing the auger screw and at least one heater coupled to the housing. The augers screw receives a build material from the storage unit and delivers the build material to a build platform via movement of the auger screw. The build material is heated by the at least one heater as the build material is being moved by the auger screw.

Abstract: Methods and devices for setting a printing distance in a 3D printing system are disclosed. In one example the method comprises forming a layer of build material below a printing plane and relatively displacing the formed layer of build material with respect to the printing plane until the distance between the formed layer of build material and the printing plane is a desired printing distance.
