Researchers from Zhejiang University have developed 3D printable elastomers with exceptional strength and toughness.

The researchers developed a 3D photo-printable resin chemistry that yields an elastomer with a tensile strength of 94.6 MPa and toughness of 310.4 MJ m-3, both of which far exceed those of any 3D-printed elastomer. They printed a rubber band that could be stretched up to nine times its original length and withstand a tensile strength of 94 MPa without breaking. Additionally, they created objects like balloons with excellent puncture resistance.
