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 (26)

1. A method of making a three-dimensional object from a solidifiable material, comprising:

providing a rigid or semi-rigid solidification substrate that is transparent and/or translucent and a first film layer that is transparent and/or translucent;

providing a peeling member;

solidifying the solidifiable material in contact with the first film layer to

create a solidified object section while maintaining a substantially fixed distance between the rigid or semi-rigid solidification substrate and the peeling member, wherein the first film layer is disposed between the rigid or semi-rigid solidification substrate and the peeling member;

moving the peeling member along the length of the first film layer while maintaining the substantially fixed distance between the peeling member and the rigid or semi-rigid solidification substrate to peel the first translucent film layer from the solidified object section;

providing a second film layer that is transparent and/or translucent between the first film layer and the rigid or semi-rigid solidification substrate; and

admitting air between the second film layer and the rigid or semi-rigid solidification substrate.

2. The method of claim 1 , wherein the second film layer includes a relieved section.

3. A method of producing a three-dimensional object from a solidifiable material, comprising:

providing solidifiable material between a previously solidified object section and a solidification substrate;

determining a first force applied to the solidification substrate;

supplying solidification energy to the solidifiable material based on the first force;

moving the previously solidified object section away from the solidification substrate, determining a second force applied to the solidification substrate, and traversing a peeling member along the length of the solidification substrate based on the second force.

4. A method of producing a solidifiable object from a solidifiable material, comprising:

providing a source of solidifiable material having a total exposable area to which solidification energy may be supplied;

supplying solidification energy exclusively to a sub-area of the total exposable area while the sub-area is at a first location with respect to the total exposable area;

moving the sub-area in a first direction to a second location with respect to the total exposable area; and

supplying solidification energy exclusively to the sub-area of the total exposable area while the sub-area is at the second location with respect to the total exposable area, wherein the step of supplying solidification energy exclusively to a sub-area of the total exposable area while the sub-area is at the first location with respect to the total exposable area comprises transmitting solidification energy from a source of solidification energy into a first surface of a rigid or semi-rigid substrate that is transparent and/or translucent and transmitting the solidification energy from a second surface of the rigid or semi-rigid substrate and into the solidifiable material, wherein the first surface of the rigid or semi-rigid substrate has a first surface area, the second surface of the rigid or semi-rigid substrate has a second surface area, and the first rigid or semi-rigid substrate surface area is greater than the second rigid or semi-rigid substrate surface area.

5. The method of claim 4 , wherein the rigid or semi-rigid substrate has a beveled edge.

6. A method of producing a solidifiable object from a solidifiable material, comprising:

providing a source of solidifiable material having a total exposable area to which solidification energy may be supplied;

supplying solidification energy exclusively to a sub-area of the total exposable area while the sub-area is at a first location with respect to the total exposable area; moving the sub-area in a first direction to a second location with respect to the total exposable area;

supplying solidification energy exclusively to the sub-area of the total exposable area while the sub-area is at the second location with respect to the total exposable area

moving the sub-area in a second direction to the first location; and

supplying solidification energy exclusively to the sub-area of the total exposable area while the sub-area is at a first location with respect to the total exposable area.
