Abstract
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.
