摘要： A 3D printer is disclosed herein. The 3D printer comprises an energy source comprising solid-state emitters to selectively emit energy to a build material layer in a narrow-band of wavelengths; an agent delivery device to selectively deposit a fusing agent, a detailing agent and a reflective agent on the build material layer in respective independent patterns; and a controller. The reflective agent is to reflect substantially all of the energy at the wavelengths within the narrow-band of wavelengths. The controller is to control the agent delivery device to selectively deposit the fusing agent to a build material layer in a first pattern corresponding to a 3D object to be generated. The controller is further to control the agent delivery device to selectively deposit the detailing agent and the reflective gent to the build material layer in a second pattern and third pattern respectively. The controller is also to control the energy source to apply energy to the first pattern and second pattern in the narrow-band of wavelengths.

摘要： A reflector includes a first reflector section and a second reflector section. The first reflector section extends along a portion of a first ellipse. The second reflector section extends along a portion of a second ellipse, the second ellipse intersecting the first ellipse. The first reflector section and the second reflector section are joined at an intersecting point of the first ellipse and the second ellipse.
