SUBSTRATE-BASED ADDITIVE FABRICATION PROCESS AND APPARATUS

摘要

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.
