    Abstract: An illumination system includes a green light source, a red light source, a blue light source, a first splitter, a second splitter, and a thermoelectric cooler. The first splitter is disposed downstream of the light sources, the first splitter being capable of reflecting a first color light beam and allowing a second color light beam to pass. The second splitter is disposed at the light paths of the light sources, and the second splitter being capable of reflecting a third color light beam and allowing the first color light beam and the second color light beam to pass, wherein the color of the first color light beam, the second color light beam, and the third color light beam are substantially different. The thermoelectric cooler is thermally coupled to the red light source, and neither the green light source nor the blue light source is thermally couple to any thermoelectric cooler.

    Abstract: A three-dimensional printer includes a projector, a tank, and a platform. The projector includes a light source, a digital micromirror device, and a controller. The digital micromirror device includes a micromirror, and the micromirror may be switched between an on state and an off state according to a control signal. The controller is electrically connected to the digital micromirror device and the light source. The controller further includes a judgement unit. The judgement unit may output the control signal to switch the micromirror to the off state when the light source is in the off state. The platform is adjacent to the tank. In addition, a manufacturing method for a three-dimensional printer is provided.
