Carbon, the fast-growing 3D printing business, is raising up to $300M

Carbon, the poster child for 3D printing, has authorized the sale of $300 million in Series E shares, according to a Delaware stock filing uncovered by PitchBook. If Carbon raises the full amount, it could reach a valuation of $2.5 billion.

Using its proprietary Digital Light Synthesis technology, the business has brought 3D printing technology to manufacturing, building high-tech sports equipment, a line of custom sneakers for Adidas and more. It was valued at $1.7 billion by venture capitalists with a $200 million Series D in 2018.

Carbon declined to comment on its upcoming fundraising plans.

Redwood City-based Carbon is well-capitalized. To date, it’s raised a total of $422 million from investors like Sequoia, GV, Fidelity, General Electric, Hydra Ventures and Adidas Ventures, not including the incoming round of capital.
