Matrix-filled liquid radiation curable resin compositions for additive fabrication are described and claimed. Such resins include a cationically polymerizable component that is an aliphatic epoxide, a multifunctional (meth)acrylate component, a cationic photoinitiator, a free-radical photoinitiator, and a matrix of inorganic fillers, wherein the matrix further constitutes prescribed ratios of at least one microparticle constituent and at least one nanoparticle constituent. Also described and claimed is a process for using the matrix-filled liquid radiation curable resins for additive fabrication to create three dimensional parts, and the three-dimensional parts made from the liquid radiation curable resins for additive fabrication.

Stabilized matrix-filled liquid radiation curable resin compositions for additive fabrication

The invention relates to radiation curable compositions comprising a liquid 0/s(acyl)phosphine photo initiators of formula (&#xcf;): wherein each of Ar, Arand Aris independently a substituted or unsubstituted aryl group. The invention also relates to stabilized forms of liquid bis(acyl)phosphines of formula (I) and radiation curable composition comprising said stabilized photoinitiators. The radiation curable compositions are selected from the group consisting of an optical fiber coating composition and a coating composition capable of radiation cure on concrete and a coating composition capable of radiation cure on metal.
