By combining wavelength-selective resin design with tailored thermal treatments, SSVP advances photopolymerization 3D printing, enabling the creation of differentially soluble polymer networks within monolithic components. This approach allows for the fabrication of complex internal features without the need for mechanical support removal, eliminating geometric design constraints except for solvent accessibility. Selective solubility could be expanded to additional wavelengths and functionalities, such as locally tuning mechanical, optical, or electronic properties through variable crosslink density. Additionally, SSVP can support fully automated workflows, enabling waste-free mass production via robotic material handling and continuous resin recycling.
