Summary: | Radiation curable compositions for additive fabrication with improved toughness are described and claimed. Such resins include a rubber toughenable base resin package and a liquid, phase-separating toughening agent. The rubber toughenable base resin, which may possess a suitably high average molecular weight between crosslinks and may be a pre-reacted hydrophobic macromolecule, may further include a cationically polymerizable component, a radically polymerizable component, a cationic photoinitiator, a free radical photoinitiator, and customary additives. Also described and claimed are methods for forming a three-dimensional objects using such radiation curable compositions for additive fabrication with improved toughness, along with the three-dimensional parts created therefrom. |
