Redwood City, California – Digital manufacturing specialist Carbon is launching a new rigid polyurethane for 3D printing. The dual-cure resin, RPU 130, is being launched at the K show in Dusseldorf.
Carbon adds high-performance rigid PU resin for additive manufacturing

Painted and unpainted brake caliper covers benefit from RPU 130’s strength and heat resistance qualities
The new grade of rigid polyurethane resin was designed to give good impact resistance and dimensional stability at elevated temperatures. This makes it particularly suitable for automotive applications. The company says it is also appropriate for a range of industrial and consumer product applications, including sunglasses, tool housings and device enclosures.
The raw materials used to make RP-130 include Susterra propanediol from DuPont Tate & Lyle. This plant-based diol comprises almost 30% of the resin.
‘RPU 130 represents a true breakthrough in what is possible for new additive materials,’ said Joseph DeSimone, co-founder and CEO of Carbon. ‘Although some of these properties have been available before in additive, RPU 130 is the first to combine them all into a single manufacturing material suitable for the most demanding conditions. We are really proud of the science that went into bringing this innovative material to market.’
