Unlike similar materials in DLP printing, Elastic ToughRubber™ is a one part, one pot polymer system. This means there is no mixing of two materials in the proper ratios, which can lead to poor quality if not done correctly. ETR is also pot stable so there is no wasted resin at the end of the print. You simply use the left over resin to print your next part!
Elastic ToughRubber™ can already be found in parts and products that are sold on store shelves. It is perfect for shoe midsoles and heel cups, seals, door boots, bellows, recoil pads, foam-like lattice structures and impact parts.
In the past, it has been difficult, slow and expensive to additively manufacture elastomeric materials with rubber and polyurethane-like performance that have consistent performance in freezing, cold, warm, hot and moist conditions.
Digital Light Processing (DLP) and Stereolithography (SLA) typically require viscous materials resulting in low elasticity, poor tear strength and small strain capacity. Recent materials and equipment developments have led to elastomeric offerings that deliver high performance. However, with thermal transitions inside use ranges (e.g. 6°C or -9°C), they have a very limited operational temperature window and cannot perform consistently in colder environments and they require over 8 hours of post processing, leading to low throughput and high total part production time.
Elastic ToughRubber™ (ETR) is a tough printable elastomer for all seasons. ETR unlocks the benefits of additive manufacturing to those who manufacture and sell rubber, polyurethane and foam parts. With a tear strength of 43 kN/m, >200% elongation, ultimate tensile strength of >10 mPa, and Shore A 90 durometer, Elastic ToughRubber approaches the properties of leading injection molded thermoplastic polyurethanes like PEBAX® and Elastollan®.
Additionally, by eliminating the thermal cure stage required by other well-known 3D printable elastomers, which are promoted as high-speed printing, ETR reduces the total post processing time by as much as 10 hours. Additive manufacturing must deliver stable performance over a broad temperature window. With thermal transitions (-65°C and 75°C) spanning ambient temperature ranges, ETR is optimized for both cold weather environments and hot, humid conditions. If you make parts such as technical foams, rubbers or polyurethanes, ETR is your solution to additive manufacturing end parts and products.
