DURABLE

Product catalog summary

Overview: The document provides detailed material properties for the Durable photopolymer resin used in Form 2 3D printers. This resin is designed to simulate polypropylene (PP) plastic, offering low modulus and high-impact strength, suitable for parts requiring deformation and a smooth, glossy finish. Post-curing is recommended for optimal mechanical properties.

Material Specifications:

Tensile Properties: Ultimate tensile strength is 18.6 MPa (green) and 31.8 MPa (post-cured). Tensile modulus is 0.45 GPa (green) and 1.26 GPa (post-cured). Elongation is 67% (green) and 49% (post-cured).
Flexural Properties: Flexural stress at 5% strain is 4.06 MPa (green) and 27.2 MPa (post-cured). Flexural modulus is 0.16 GPa (green) and 0.82 GPa (post-cured).
Impact Properties: IZOD impact strength is 130.8 J/m (green) and 109 J/m (post-cured).
Temperature Properties: Heat deflection temperature at 0.45 MPa is less than 30°C (green) and 43.3°C (post-cured). Thermal expansion from 23 to 50°C is 117.0 μm/m/°C (green) and 145.1 μm/m/°C (post-cured).

Solvent Compatibility: The document lists the percent weight gain over 24 hours for a printed and post-cured cube immersed in various solvents. Notable results include:

Acetic Acid (5%): 1.3% weight gain
Acetone: Sample cracked
Isopropyl Alcohol: 5.1% weight gain
Butyl Acetate: 7.9% weight gain
Xylene: 6.5% weight gain
Strong Acid (HCI Conc): Sample distorted

Most other solvents resulted in less than 1% weight gain.

Notes: Material properties can vary based on part geometry, print orientation, print settings, and temperature. Data was obtained from green parts printed using Form 2 at 100 μm settings, with post-curing involving 2.5 mW/cm² of 405 nm LED light for 120 minutes at 60°C.
