Abstract

A solidification substrate assembly for making a three-dimensional object from a solidifiable material includes a solidification substrate assembly. In certain examples, the solidifiable material solidifies in contact with the solidification substrate, and the tilting of the substrate and/or or the use of a peeling member facilitates separation of the substrate from the solidified material. In other examples, the solidification substrate assembly includes a film that is adjacent to a rigid or semi-rigid layer. The solidifiable material solidifies in contact with the film, and a peeling member peels the film away from the solidified material. Intelligent solidification substrate assemblies are also described in which a force sensor determines when to expose the solidifiable material to solidification energy and/or whether to use a peeling member to separate the solidification substrate from a solidified objection section.

Claims (15)

1. A multi-layer assembly for making a three-dimensional object by solidifying a solidifiable material, comprising:

a rigid or semi-rigid solidification substrate assembly comprising a frame and a rigid or semi-rigid translucent solidification substrate disposed in the frame;

a film assembly, wherein the rigid or semi-rigid solidification substrate assembly is connected to the film assembly, and the film assembly includes at least one frame and a film disposed in the at least one frame.

2. The multi-layer assembly of claim 1 , wherein the film is a fluoropolymer.

3. The multi-layer assembly of claim 2 , wherein the fluoropolymer is one selected from the group consisting of a modified fluoroalkoxy film, a perfluoroalkoxy film, a polyvinylidene fluoride film, an ethylenechlorotrifluoroethylene film, an ethylenetetrafluoroethylene film, and a polytetrafluoroethylene film.

4. The multi-layer assembly of claim 1 , further comprising an air path between the rigid or semi-rigid translucent solidification substrate and the film.

5. The multi-layer assembly of claim 4 , wherein the film and the rigid or semi-rigid translucent solidification substrate assembly are adjacent one another along a build axis.

6. The multi-layer assembly of claim 1 , wherein the film and the rigid or semi-rigid translucent solidification substrate assembly are adjacent one another along a build axis.

7. The multi-layer assembly of claim 1 , wherein the at least one frame comprises an inner and an outer frame, and the film and the rigid or semi-rigid translucent solidification substrate assembly are adjacent one another along a build axis.

8. The multi-layer assembly of claim 7 , wherein a peripheral portion of the film is disposed between the inner frame and the outer frame.

9. An apparatus for making a three-dimensional object by solidifying a solidifiable material, comprising:

the multi-layer assembly of claim 1 ;

a pattern generator positioned to project solidification energy through the multi-layer assembly;

a volume of the solidifiable material;

a build platform spaced apart from the pattern generator along a build axis, wherein the build platform is movable along the build axis.
