Abstract
A three dimensional printing apparatus including a carrying plate, a transparent plate, an elastic film, and a bump is provided. The transparent plate is disposed on the carrying plate. The elastic film is disposed on the transparent plate. The bump is disposed between the elastic film and the carrying plate. An interface between the transparent plate and the elastic film is in communication with an external space through a fluid channel between each bump and the elastic film. An orthographic projection area of the bump on the transparent plate is not more than ¼ of a surface area of the transparent plate.
Claims17
A three dimensional printing apparatus, comprising:
- a carrying plate;
- a transparent plate disposed on the carrying plate;
- an elastic film disposed on the transparent plate;
- and
- a bump disposed between the elastic film and the carrying plate, wherein an interface between the transparent plate and the elastic film is in communication with an external space through a fluid channel between the bump and the elastic film, and an orthographic projection area of the bump on the transparent plate is not more than 1/4 of a surface area of the transparent plate.
A three dimensional printing apparatus, comprising:
- a carrying plate;
- a glass plate disposed on the carrying plate;
- a release film disposed on the glass plate;
- a spacer disposed between the release film and the carrying plate, a gap exists between the glass plate and the release film, and a fluid is located between the release film and the glass plate through the gap;
- and
- a projector disposed on an upstream of a light path of the glass plate and suitable for providing a light beam towards the glass plate, wherein the spacer is located outside a projection range of the projector.
