Description
Sarah Finnegan, Allison Kinsey, and Andrew Boydston wrote this 2025 study on printing objects made of many materials in a single run. Vat photopolymerization builds parts in liquid resin, and swapping resins mid-print is painful. Their method prints with two wavelengths of light, creating regions inside one part that differ in how eagerly they soak up dissolved substances afterward.
They then infused the printed parts selectively: organic dyes for patterned color, silicone resins for mechanical contrast, and metal salts for conductivity. A gentle heating step after infusion converted silver salts into metal, yielding working circuits with conductive and insulating domains from one print. The authors call the technique iMASC-AM and pitch it as a back door into multimaterial printing. Instead of changing resins during the print, the chemistry is loaded afterward, region by region.
