Elastic

Product catalog summary

Material Overview: Elastic Resin (FLELCL01) is Formlabs' softest engineering resin with a 50A Shore durometer, ideal for prototyping parts typically made with silicone. It is designed for applications requiring flexibility, such as wearables, consumer goods, medical models, robotics, and special effects props. The resin is priced at $199 per liter.

Mechanical Properties: The resin exhibits the following properties when tested according to ASTM standards:

Ultimate tensile strength: 3.23 MPa (post-cured)
Stress at 50% elongation: 0.94 MPa (post-cured)
Stress at 100% elongation: 1.59 MPa (post-cured)
Elongation at failure: 160% (post-cured)
Compression set at 23°C for 22 hours: 2%
Compression set at 70°C for 22 hours: 9%
Tear strength: 19.1 kN/m (post-cured)
Shore hardness: 50A (post-cured)

These properties can vary based on part geometry, print orientation, print settings, and temperature.

Solvent Compatibility: The resin's compatibility with various solvents was tested by measuring size and weight gain over 24 hours. Key findings include:

Acetone: 19.3% size gain, 37.3% weight gain
Isopropyl Alcohol: 13.3% size gain, 25.6% weight gain
Xylene: 20.4% size gain, 46.6% weight gain
Minimal size and weight gain with acetic acid, hydrogen peroxide, mineral oils, salt water, and sodium hydroxide.

Testing Conditions: Data was obtained from parts printed using Form 2 at 100 µm with Elastic settings, washed in Form Wash for 20 minutes, and post-cured with Form Cure at 60°C for 20 minutes. Tensile and tear testing were performed after 3+ hours at 23°C using specific ASTM methods.
