Elastic 50A (V2)

Translucent. Elastomeric. Soft Silicone-like Resin

Formlabs' Elastic 50A V2 resin is ideal for prototyping parts that normally would be produced with softer rubbers or silicones. It is a translucents elastomer with a 50A Shore durometer that allows 3D-printed parts to bedn, stretch, compress and hold-up to repeated cycles without tearing, and spring back quickly to their original shape.

Elastic 50A V2

Resin for Transparent, Soft, Flexible Parts.

Elastic 50A V2 resin is one of Formlabs’ most pliable stereolithography materials, with a Shore 50A durometer, high elongation, and energy return. At the same time, parts are strong enough not to tear during the 3D printing process.

Elastic 50A for the Medical Industry

How can Elastic 50A resin improve patient care and reduce costs?

In recent years, significant advancements have been made in formulating transparent and soft silicone-like 3D printing resins designed to decrease the costs of patient-specific anatomical models. Healthcare professionals, including surgeons, researchers, and radiologists, seek these advanced solutions to elevate their preparedness for intricate cases and surgical procedures.  Why? Due to the high costs and lengthy turnaround time associated with traditional medical service providers.

It is time to consider more efficient alternatives! Formlabs® developed Elastic 50A resin* to address these issues, facilitating improved communication among surgical teams and providing clear information to patients.
