Using this formulated resin, selective solubility vat photopolymerization (SSVP) was performed using a multi-wavelength projector-based printer with independent control of UV (365 nm) and visible (405 nm) light (Fig. ). After printing, components produced under 405 nm illumination were soluble in many common solvents, including mineral oil (baby oil), D-limonene, mineral spirits, turpentine (paint thinner), and toluene; parts produced under 365 nm illumination were resistant to dissolution in these same solvents. Additionally, both the visible-and UV-cured materials demonstrated good mechanical properties directly after printing, with elastic moduli of 1.1 GPa and 1.8 GPa, respectively. Exposure to UV light (365 nm) initiates free radical and cationic polymerization, resulting in a crosslinked, dissolution-resistant network after heat treatment. After printing, the thermoplastic can be dissolved away, leaving the finished thermoset part.
