Multilayer Urethane Model Elaboration
The urethane elastomer was shielded by deep-coating wax
vasculature fabricated as detailed in [4]. The irst coating was
silicone elastomer at 0.1 mm/s, then urethane elastomer coating
twice at 1 mm/s after the silicone dried. The silicone coating was
repeated after the urethane elastomer dried, and then wax was
melted to complete shielding.
