3D printing startup Carbon3D has raised $100 million in a funding round led by Google’s venture capital arm. Earlier this summer, Ford Motor Company showed off how it was testing 3D printing technology to improve its manufacturing and create new prototypes of car parts more quickly than with conventional methods. Now the startup that Ford F -2.37% tapped in the initiative has landed $100 million new in funding, led by Google Ventures. Both Carbon3D and Google Ventures declined to disclose the valuation.
