Abstract: A system, method, and apparatus for varying output power for two or more fusing lamps in a 3D printer is disclosed. For example, the system includes a first fusing lamp to operate at a first voltage and a second fusing lamp to operate at a second voltage. The system may include a controller communicatively connected to the first fusing lamp and the second fusing lamp, wherein the controller sets the first voltage and the second voltage in response to a multi-lamp power output setting, a lamp power minimum, and a lamp power maximum.

Abstract: An example system includes an imaging device and an enclosure substantially separating the imaging device from an outside environment. The enclosure includes an air intake to force air into the enclosure and an aperture to allow air to escape the enclosure. The air intake and the aperture maintain an air pressure level in the enclosure greater than an air pressure of the outside environment.
