Fig. 4. Multimaterial parts by 3P-printing.
(a) Planar (X-Y) and (b) layer-by-layer (Z) arrangement of 0% (blue), 10% (white [transparent]), and 20% (orange) PEGDA-co-PEGMEMA resins. The resin is switched twice for every 100 μm printed layer to obtain the multimaterial hexagons, whereas it is only switched twice for printing the entire multimaterial pyramid. (c) High-resolution multimaterial Eiffel tower (~15 mm-tall) fabricated by 3P-printing 0, 10, and 20% PEGDA-co-PEGMEMA resins.
