a Comparative compressive force experiments for VIS light-cured conventional Arario 410 (white bar) and UVIStar resins (gray bar). Printed object dimensions are 10 × 5 × 1 cm3. b, c SEM images of stair-like structured cured transparent UVIStar resin from a side view (b) and a top view (c). d Photos of objects printed with UVIStar resins with various dyes included: red (top left), orange (top middle), yellow (top right), green (bottom left), blue (bottom middle), and indigo (bottom right). e Demonstration of pink dye spreading from left to right and dark blue dye spreading from the middle to the edges. f Various cured colored resins in chess piece shapes printed with a VIS light lamp-equipped SLA 3D printer. The chess pieces are placed on top of a mini-chessboard, demonstrating their unprecedented colorfulness. g Absorbance spectra of colored UVIStar resins. The turquoise line represents the spectrum of UVIStar resin with tetrabromophenol blue dye, the orange line represents the spectrum of UVIStar resin with rhodamine 123, and the pink line represents the spectrum of UVIStar with rhodamine B
