Abstract
A 3D printer for building 3-dimensional object using DLP technique, comprising a solidifiable material container, an irradiation component, a supporting component, a surface regulation component, and a control system. The 3D printer realizes large dimension and high speed printing by applying a flexible film over the surface of the photopolymer resin. The flexible film is separated from the solidified resin by peeling force.
Claims19
A 3D printer for building a 3-dimensional object, comprising:
- a solidifiable material container containing a solidifiable material;
- an irradiation component comprising a projector to generate irradiation over a predetermined area of the surface of said solidifiable material for solidification;
- a supporting component supporting said under building object and leveling the top surface of said object to have new layer of solidifiable material be solidified on said object,
- a surface regulation component comprising a regulation plane transparent to said irradiation, and a supporting frame placing said regulation plane over said predetermined area of said surface of said solidifiable material to regulate said surface of said solidifiable material in flat, and
- a control system providing data to said irradiation component to generate irradiation, and controlling movement of said irradiation component, said supporting component, and said surface regulation component.

A method of building a 3-dimensional object by DLP technology, comprising steps of:
- (a) providing a transparent plane surface;
- (b) placing said plane surface over a area of the top surface of a liquid solidifiable material to regulate said area into flat;
- (c) solidifying said solidifiable material regulated by said plane surface though a projector;
- (d) separating said plane surface from said solidified area;
- (e) filling a new layer of liquid solidifiable material over said solidified area for a new layer of solidification.
