Grey Pro

Product catalog summary

Material Overview: Grey Pro Resin is a photopolymer resin designed for Form 2 3D printers, known for its high precision, moderate elongation, and resistance to deformation over time. It supports print resolutions of 100 and 50 microns and requires a Resin Tank LT.

Specifications: The material properties are provided for both green and post-cured states. Key mechanical properties include ultimate tensile strength, tensile modulus, elongation, flexural stress, and flexural modulus. The resin also has specific thermal properties such as heat deflection temperature and thermal expansion.

Mechanical Properties:

Tensile Properties: Ultimate tensile strength is 35 MPa (green) and 61 MPa (post-cured). Tensile modulus is 1.4 GPa (green) and 2.6 GPa (post-cured).
Flexural Properties: Flexural stress at 5% strain is 39 MPa (green) and 86 MPa (post-cured). Flexural modulus is 0.94 GPa (green) and 2.2 GPa (post-cured).
Impact Properties: Notched IZOD impact strength is 18.7 J/m (post-cured).
Temperature Properties: Heat deflection temperature at 1.8 MPa is 62.4°C and at 0.45 MPa is 77.5°C.

Solvent Compatibility: The document provides data on the percent weight gain over 24 hours for a printed and post-cured cube immersed in various solvents. Notable solvents include acetone with a 10.77% weight gain and strong acid (HCl Conc) with an 8.21% weight gain.

Notes: Material properties can vary with part geometry, print orientation, print settings, and temperature. Data was obtained from parts printed using Form 2, 100 μm, Grey Pro settings, and post-cured with a Formcure for 120 minutes at 80°C.
