Abstract
Example systems relate to recoater movement. A non-transitory machine readable medium may contain instructions executable by a processor. The instructions may include instructions to change an action of a recoater in response to a determination that the recoater has reached a first location of a build area comprising build material. Instructions may further include instructions to lift the recoater in response to a determination that the recoater has reached a second location of the build area. Instructions may additionally include instructions to move the recoater over the second location at the lifted position, wherein the second location includes a build-up of the build material.
Claims15
A non-transitory machine readable medium containing instructions executable by a processor to cause the processor to:
- change an action of a recoater in response to a determination that the recoater has reached a first location of a build area comprising build material;
- lift the recoater in response to a determination that the recoater has reached a second location of the build area;
- and
- move the recoater over the second location at the lifted position, wherein the second location includes a build-up of the build material.
A system, comprising:
- a controller to:
- move a recoater coupled to a carriage device over a build area in a first direction;
- determine that a recoater has reached a first location of the build area when moving in the first direction;
- reduce a first rate of rotation of the recoater in response to the determination that the recoater has reached the first location;
- and
- determine that the recoater has reached a second location of the build area, wherein the second location includes a build-up of the build material caused by a previous leveling process;
- and
- the carriage device to:
- lift the recoater over the build-up of the build material in response to the determination that the recoater has reached the second location;
- and
- move the recoater over the build-up of the build material at the second location.
A method, comprising:
- moving a recoater in a first direction over a build area to level build material on the build area;
- reducing a rate of rotation of the recoater in response to a determination that the roller has reached a first location;
- lifting the recoater in response to a determination that the recoater has reached a second location by rotating the recoater about a pivot point located above the recoater;
- moving the recoater above a build-up of build material at the second location;
- lowering the recoater in response to a determination that the recoater has moved past the build-up of build material at the second location;
- and
- moving the recoater in a second direction over the build-up of build material at the second location and the build area.
