摘要： In some examples, a system compares a first source impedance rating of a first mode of the machine to a source impedance of a power source, where the machine is operable in a plurality of modes associated with different source impedance ratings. The system enables the first mode of the machine in response to determining, based on the comparing, that the source impedance of the power source satisfies the first source impedance rating.

摘要： 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.
