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.
Claims13
A manufacturing method for a three-dimensional printer, comprising:
- disposing a projector comprising a light source, a digital micromirror device, and a controller, wherein the digital micromirror device is disposed in a light path downstream of the light source, the digital micromirror device comprises a micromirror, the micromirror is 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 comprises a judgement unit, and the judgement unit is adapted to output the control signal to switch the micromirror of the digital micromirror device from previously the on state or the off state to another different state when the light source is in the off state;
- disposing a tank in the light path downstream of the projector;
- and
- disposing a platform to be adjacent to the tank.
A three-dimensional printer, comprising:
- a projector comprising:
- a light source;
- a digital micromirror device disposed in a light path downstream of the light source, and a micromirror on the digital micromirror device is switched between an on state and an off state according to a control signal;
- and
- a controller electrically connected to the digital micromirror device and the light source, the controller adapted to output the control signal to switch the micromirror of the digital micromirror device from previously the on state or the off state to another different state when judging the light source is turned off;
- a tank disposed in the light path downstream of the projector;
- and
- a platform disposed adjacent to the tank.
