Abstract: According to one example, there is provided a method of distributing build material in a 3D printing system. The method comprises moving a build material support positioned below a hopper, the movement to cause build material stored in the hopper to be deposited on the build material support, and moving a recoater to spread build material from the build material support over a build platform to form a layer of build material thereon, and to return any excess build material back to the build material support.

Abstract: In one example, an encoder strip mounting system includes an encoder strip having a first end, a second end opposite the first end, and an intermediate part between the first end and the second end, and a retainer to prevent the intermediate part of the encoder strip from shifting lengthwise with respect to an anchor point for the retainer located within a span of the intermediate part of the encoder strip.
