Abstract
En 中文
• PCT and resin grade control SLA resin stiffness, strength, and energy absorption. • The 25-40 °C step gives the largest gain in flexural properties. • Stiffness and strength reach a saturation window above 70 °C. • White V4 becomes stronger but more brittle after post-curing. • Tough 2000 preserves ductility and doubles energy absorption at 80 °C.
