MATERIAL DATA SHEET Flexible

Product catalog summary

Material Overview: The document provides detailed information about Formlabs' Flexible Resin, identified as FLFLGR02, designed for use in Form 2 3D printers. This resin is ideal for creating parts that require flexibility, such as ergonomic features, soft-touch materials, and cushioning components. It is particularly suitable for applications like handles, grips, overmolds, wearables prototyping, packaging, and stamps.

Pricing: The resin is priced at $199 per liter.

Mechanical Properties:

Ultimate Tensile Strength: Ranges from 3.3 - 3.4 MPa (green) to 7.7 - 8.5 MPa (post-cured), equivalent to 483 - 494 psi and 110 - 1230 psi respectively.
Elongation at Failure: 60% (green) and 75 - 85% (post-cured).
Compression Set: Consistent at 0.40% for both green and post-cured states.
Tear Strength: 9.5 - 9.6 kN/m (green) and 13.3 - 14.1 kN/m (post-cured), equivalent to 54 - 55 lbf/in and 76 - 80 lbf/in respectively.
Shore Hardness: 70 - 75 A (green) and 80 - 85 A (post-cured).

Thermal Properties:

Vicat Softening Point: 231 °C (green) and 230 °C (post-cured), equivalent to 448 °F and 446 °F respectively.

Solvent Compatibility: The document lists the percent weight gain over 24 hours for a 1 x 1 x 1 cm cube immersed in various solvents, indicating the resin's resistance to different chemicals. Notable results include:

Acetone: 33% weight gain
Xylene: 29% weight gain
Isopropyl Alcohol: 9.8% weight gain
Butyl Acetate: 16% weight gain
Diethyl glycol monomethyl ether: 30% weight gain
Minimal weight gain (<1%) in Isooctane and Salt Water (3.5% NaCl)

Testing Conditions: The data was obtained from parts printed using Form 2, 100 µm, Flexible settings, and post-cured with 80.5 mW/cm² of 365 nm fluorescent light for 60 minutes. Various mechanical and thermal tests were conducted under specific conditions, such as tensile testing at 23 °C and thermal testing with a 10 N loading at 50 °C/hour.
