EnvisionTEC, a 3D printing solutions company, launches today a groundbreaking new material, E-RigidForm. The company showcased it in a 328-foot 3D printed chain Friday morning at Cobo Center in downtown Detroit and is claiming the record for the world's longest single-piece chain using 3D printing technology.

E-RigidForm is a polyurethane-like resin that 3D prints hard and stiff parts. With a high tensile strength of 68-73 MPa at 7% elongation at break, E-RigidForm is probably one of the most durable printing materials ever developed in 3D printing.

“E-RigidForm is a breakthrough material for use on our 3SP line of 3D printers, which offer very large build areas without sacrificing speed and accuracy,” said EnvisionTEC CEO Al Siblani. E-RigidForm joins an industry-leading materials portfolio at EnvisionTEC that now features 50 materials.

The EnvisionTEC Mega-Chain is 328-feet long and was 3D printed in one piece. It contains 6,144 links, each measuring 1.5". The 16-layer job took 99 hours to print unattended over 4 days. The chain was 3D...
