Next week, Adaptive3D will introduce a high tear-strength direct curing rubber and polyurethane-like elastomer at FormNext in Frankfurt. Elastic ToughRubber 90 (ETR) is a photoresin designed for DLP-based 3D printing of flexible end parts and products in the footwear, transportation, industrial and medical spaces.

In the past, it has been challenging to additively manufacture elastomeric materials with rubber and polyurethane-like performance, especially those with sufficient strain capacity. Fused Filament Fabrication (FFF) and Selective Laser Sintering (SLS) of elastomeric thermoplastics result in properties and parts that are used primarily for prototyping. DLP and Sterolithography (SL) printing require viscous materials with low elasticity, poor tear strength and small strains. Other DLP and SL approaches require long and aggressive thermal post processes to form a secondary strong polymer network to displace the first printed, weaker network.

“Elastic ToughRubber 90 is a tough printable elastomer for all seasons,” said Adaptive3D CEO Walter Voit, PhD. He went on to say, “with stable performance at cold temperatures, a tear strength of 46 kN/m, greater than 200% elongation, and ease of processing, Elastic ToughRubber unlocks the benefits of 3d printing to those who manufacture and sell rubber, polyurethane and foam parts.”

The photopolymer resin is a one-part system that does not need mixing, which ensures higher part-to-part quality. It is also pot stable, meaning that leftover resin can be used in the following prints, which reduces expensive waste and overcomes the significant environmental challenges of other elastomeric polyurethane photopolymers.

Parts made from Elastic ToughRubber™ will be displayed at Booth 12.1 G01 at FormNext in Frankfurt, Germany from November 19th -22nd.
