Abstract: A light path adjustment mechanism includes a bracket, a light valve, a carrier, a first axis, a second axis and an optical plate member. A surface normal of a surface of the light valve crosses the bracket to define an intersection closest to the surface of the light valve, and the bracket has an end point furthest from the intersection measured in the direction of the surface normal. A distance between the intersection and the surface measured in the direction of the surface normal is smaller than a distance between the intersection and the end point measured in the direction of the surface normal.

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.

Abstract: A three dimensional printing apparatus includes a carrier, a glass plate and a film. The glass plate is disposed on the carrier. The film covers the glass plate and is folded over an edge of the carrier. An interface between the glass plate and the film is in communication with the external space via a channel between the edge and the sidewall of the glass plate.

Abstract: An image displacement device includes a first grating and a second grating. Each grating is switchable between a diffracting state and a non-diffracting state. The first grating has a first surface and a second surface opposite the first surface, the first surface receives image beams, and the image beams leave the first grating by the second surface. The second grating is disposed downstream from the first grating in a light path and has a third surface and a fourth surface opposite the third surface. The third surface receives the image beams, and the image beams leave the second grating by the fourth surface. An exit direction of the image beam exiting the second grating is shifted a distance in a first direction from an incident direction of the image beam incident to the first grating.

Abstract: An image displacement device includes a projection lens and a first grating. The projection lens has a lens group, and the lens group includes a first lens and a second lens, where no lens with refractive power is disposed between the first lens and the second lens. The first grating is switchable between a diffracting state and a non-diffracting state, and the first grating is disposed on one side of the first lens facing away from the second lens. A distance between the first grating and an aperture stop of the projection lens measured along an optical axis of the projection lens is smaller than a distance between the first grating and the second lens measured along the optical axis of the projection lens.
