An apparatus and method for additive fabrication which helps to prevent the newly hardened layer from being separated from the previously formed layer of the object while the foil is peeled from the newly hardened layer is provided. In one embodiment, use of a peel angle helps prevent the newly hardened layer from being separated from the previously formed layer during peeling by distributing the peeling force so that less of the z-direction component of the peeling force is applied to the newly hardened layer. In another embodiment, the object can be oriented to initiate the peel at an area, of the object which results in a lesser initial peeling force applied to the newly hardened layer.

Apparatus and method for the separation of a foil from a material layer

A method and apparatus for additive fabrication which provides a substrate which helps the newly hardened resin layer to separate from the substrate while providing a substrate of appropriate strength and durability. In an embodiment, the substrate is a multi-layer substrate comprising a transport layer and a structural layer, the transport layer comprising a polyolefin or a fluoropolymer, and the structural layer comprising a semi-crystal line thermoplastic polymer.

Substrate-based additive fabrication process and apparatus

A system and method for layer-by-layer production of an object is provided. The system includes a construction shape having a carrying surface adapted for carrying a layer of build material, a plate having a holding surface adapted for holding an object in an object build area, a moveable reservoir having a plurality of containment surfaces defining a containment area adapted for containing a volume of build material within the moveable reservoir, and an exposure unit adapted for exposing at least a portion of the layer of build material in the object build area so that the portion of the layer of build material solidifies to form a solidified layer of the object.
