Abstract
The present disclosure provides a novel method of 3D printing using frontal polymerization chemistry. This method enables the printing of tough, high quality thermosets in a short time with the option of adding fiber reinforcement. As such, it facilitates fabrication of mechanically robust 3D-printed devices and structures.
Claims19
A composition for a thermoset gel comprising a mixture of an organic phosphite, a ruthenium(II) catalyst, a cycloalkene, and an organic solvent,
- wherein the mixture forms a thermoset gel having a storage modulus of about 10 Pascals to about 10,000 Pascals,
- wherein the cycloalkene is selected from the group consisting of norbornene, dicyclopentadiene, cyclobutene, cyclooctene, cyclooctadiene, cyclooctatetraene, and combinations thereof.
A composition for a thermoset gel comprising a mixture of an organic phosphite, a ruthenium(II) catalyst, a cycloalkene, and an organic solvent,
- wherein the mixture forms a thermoset gel having a storage modulus of about 50 Pascals to about 5000 Pascals.
