This study explores the incorporation of organosolv (LGO) and deep eutectic solvent-derived (LGD) lignin, both native and acrylated, into a 50:50 wt % mixture of two biobased monomers, polyethylene glycol dimethacrylate (PEG200DMA) and 1,10-decanediol diacrylate (C10DA), for digital light processing (DLP). Lignin physicochemical properties, dispersion stability, and UV absorptivity were characterized to predict effects on printability. Native lignin strongly reduced light penetration, requiring
