The former chairman and CEO of DuPont will be taking her big-business experience to the top job of a 3-D printing startup, the company announced today.

Ellen Kullman has been appointed CEO of Carbon, a San Francisco-area company founded by Joseph DeSimone, who is stepping down from the senior management post and will become executive chairman of Carbon’s board. Kullman has been a Carbon board member since 2016.

Kullman shared the news in a post on Linked In, saying it was “an honor and a joy” to take on the new role, calling DeSimone “one of the greatest entrepreneurs and scientists of our time. Joe has built Carbon into the world’s leading digital manufacturing platform.”


The company said Kullman’s appointment was part of an ongoing plan to “strengthening its leadership bench over the past several months.”

DeSimone co-invented the Digital Light Synthesis™ (DLS™) technology that enables digital production of higher quality at faster speeds and greater volume. He founded the company in 2013 after a twenty-year career in academia at the University of North Carolina.

Kullman served as DuPont’s CEO from 2009 to 2016

Kullman, who grew up in Wilmington and is a Tower Hill School graduate, joined DuPont in 1988. She served as the company’s 19th CEO – and first female leader – from 2009 until 2016.

According to CNBC, the Redwood City, Carbon has raised at least $260 million in venture and growth funding and attained a valuation of around $2.5 billion. Investors include Madrone Capital, Baillie Gifford, BMW Group, GV (the venture investing arm of Google parent company Alphabet), Sequoia Capital and others.
