Abstract
An apparatus and a method for the separation of a material layer (4) hardened on a flat plane (2) serving as a reference by means of a flexible, elastic separating layer (1) arranged between plane and material layer and designed in the form of a film or a gel-like material, are provided.
Claims20
An apparatus for the separation of a material layer that is hardened on a flat plane, which serves as a reference, the apparatus comprising:
- a layer of a flexible, elastic separating film arranged between the flat plane and the material layer, wherein the film does not adhere to the plane and wherein a gaseous or liquid medium can flow between the film and the plane, either
- wherein the flat plane has a surface facing the film, and the surface comprises a certain surface roughness to ensure supply or removal of the medium;
- or
- wherein the film has a surface facing the plane, the surface comprising a microstructure to ensure supply or removal of the medium.
An apparatus for the separation of a material layer that is hardened on a flat plane, which serves as a reference, the apparatus comprising:
- a layer of a flexible, elastic separating film arranged between the flat plane and the material layer, wherein the film does not adhere to the plane and wherein a gaseous or liquid medium can flow between the film and the plane,
- the apparatus further comprising a chamber between the plane and the film and means for providing negative pressure to the chamber to effect separation of said flexible, elastic separating film from a hardened material layer.
An apparatus for the separation of a material layer that is hardened on a flat plane, which serves as a reference, the apparatus comprising a flexible, elastic separating layer arranged between plane and material layer, the elastic separating layer comprising a gel-like elastic material that is applied directly to the plane.
An apparatus for the separation of a material layer that is hardened on a flat plane, which serves as a reference plane, the apparatus comprising:
- a flexible, elastic separating layer of a high-elasticity film arranged between plane and material layer;
- a basin formed above said flexible, elastic separating layer, wherein a photohardening, liquid material for forming the hardened material layer is located in said basin such that said photo hardening, liquid material is allowed to be automatically entrained in the gap between the film and the hardened layer during the separation process;
- and
- means for stretching the film in the reference plane when separating the film and the material layer.
