Microscale 3D printer manufacturer Boston Micro Fabrication (BMF) has announced the closure of a $43 million Series C funding round. Led by Chinese VC firm Shenzhen Capital Group Co. (SCGC), the investment comes at a time of significant growth for BMF, which has managed to double its global install base over the last year. Using the capital raised from the move, the company now plans to step up its expansion, by investing in product R&D and building out its marketing team.
