Abstract

A light-curable composition is provided which may be used as a photopolymerizable material in an additive manufacturing process. The additive manufacturing process involves heating the light-curable composition which has a viscosity at 20° C. of at least 20 Pa·s. The light-curable composition includes a photopolymerizable matrix material, at least one thermoplastic polymer dissolved therein, and at least one photoinitiator. Polycaprolactone or a derivative thereof is used as the dissolved thermoplastic polymer.
