    摘要： Disclosed is a photocurable resin composition for additive fabrication comprising a polymerizable component that is polymerizable by free-radical polymerization, cat ionic polymerization, or both free-radical polymerization and cationic polymerization, and a photoinitiating system capable of initiating the free-radical polymerization, cationic polymerization, or both free-radical polymerization and cationic polymerization. The photocurable resin composition is a liquid at about 25° C., and is capable of curing to provide a solid upon irradiation with light emitted from a light emitting diode (LED), wherein the light has a wavelength of from about 100 nm to about 900 nm. Also disclosed is a three-dimensional article prepared from the photocurable resin composition for additive fabrication, and a process for preparing three-dimensional articles by additive fabrication.

    摘要： The invention relates to a substrate-based method for forming a three-dimensional object by additive fabrication by coating a liquid radiation curable resin comprising from 30 to 80 wt % of cationically curable compounds on a substrate, contacting the liquid radiation curable resin with a previously cured layer, selectively exposing the layer of liquid radiation curable layer to actinic radiation thereby forming a cured layer, separating the cured layer at the substrate, and repeating the steps a sufficient number of time in order to build up a three-dimensional object.
