What is material toughness?

Toughness is the ability of a material to deform plastically and to absorb energy before fracture in the process. It can be measured by tensile testing. The material with high toughness means that a lot of energy is absorbed before fracture. The key to toughness is a good combination of strength and ductility.

Properties of High Toughness Resin(3121)

It is an excellent engineering-grade material for 3D Printing face mask respirator, prosthetics, gauntlet, shoe soles, and sports products.

Both flexible and rigid

Face mask respirator 3D printed with 3121 resin, need a shell that fits comfortably on the face. So the material needs to be a rigid material with flexibility.


High impact toughness

3121 resin is a fracture-resistant resin material that is ideal for the manufacture of prostheses, gauntlet, shoe soles, and sports products.

A good combination of strength and ductility

Elongation at break percentage: 40-50%. 3D printed coils/springs using 3121 resin have high strength and high ductility.

    1. The resin’s raw materials import from international chemical giants,just to ensure the resin’s quality and performance.
    2. High toughness, but not soft, high impact resistance, and has a certain temperature resistance.
    3. Linear shrinkage and volume reduction, high surface accuracy, good dimensional stability.
    4. Low calorific value when printing, not easy to damage the release film.
    5. Matte color, more in line with the industrial printing parts of the appearance needs.
    6. Low smell, less skin irritation
