Resin solidification substrate and assembly

摘要

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.

主权项

1. A method of producing a three-dimensional object on a build platform from a solidifiable material, wherein the build platform moves along a build axis, the method comprising:
providing a source of solidifiable material having a total exposable area perpendicular to the build axis to which solidification energy may be supplied; supplying solidification energy exclusively to a first sub-area of the total exposable area where the first sub area is at a first location along a horizontal axis with respect to the total exposable area; and then supplying solidification energy exclusively to a second sub area that is the same size as the first sub area of the total exposable area where the second sub area is at a second location along the horizontal axis with respect to the total exposable area.
