Beschreibung
Zusammenfassung:	Described herein are photopolymerizable compositions for use in 3D printing. The compositions contain highly crosslinkable acrylate monomers, elastic urethane acrylate oligomers, photoinitiator and optionally carbon black. The compositions, after photopolymerization, have a high heat deflection temperature (for example, at least 80C), while maintaining strong mechanical properties, such as E modulus, tensile strength, and elongation at break. Also described are methods for fabricating three dimensional objects utilizing these compositions, and three dimensional objects made from these compositions.
