Stereolithography Resins: Standard, Tough, Durable, Flexible, and High-Temperature — A Mechanical Properties Atlas
SLA resins span an enormous property range: standard resins offer 35–55 MPa tensile with high stiffness but brittleness (2–5% elongation), while tough/durable engineering resins achieve 45–60 MPa with 20–50% elongation. High-temperature resins maintain HDT above 200°C. We compile a comprehensive mechanical properties atlas comparing Formlabs, Siraya Tech, and generic resin families across six performance dimensions, referencing ISO and ASTM test standards.
SLA resins bukanlah satu material — mereka adalah spektrum dari standard (brittle, high-detail) hingga engineering (tough, durable, heat-resistant) hingga specialty (castable, biocompatible). Kami mengompilasi atlas properti mekanik dari Formlabs, Siraya Tech, dan pengujian independen.

| High-Temp | 40–55 | 1–3% | 60–80 | 160–230 | Mold tooling |
| Flexible | 3–10 | 80–200% | — | — | Gaskets, seals |
| Castable | 20–30 | 1–3% | 30–40 | — | Jewelry, dental |
Kapan SLA Mengungguli FDM
- Surface finish: SLA Ra 1–5 μm vs FDM 10–25 μm
- Fine details: SLA 25–50 μm XY vs FDM 400 μm
- Watertightness: SLA inherently waterproof
- Isotropy: SLA nearly uniform strength; FDM highly anisotropic
- Transparency: Clear resin → optically clear with polishing
