Us based 3D printer OEM BMF (Boston Micro Fabrication) which makes micro 3D printers, raised $24 million in a Series D round led by China’s Guotai Junan Securities. Also participating were Chongqing Chengxing Equity Investment Fund Partnership, Chuanghe Xincai Manufacturing Sector Transformation and Upgrading Fund. The company has $79.3 million so far. The Chinese money is a salient detail since last week the Biden administration stopped US companies from investing semiconductors, microelectronics, some quantum and AI in China. But, what about Chinese money for US startups? And what about companies doing research in China? Must a company such as BMF choose to be funded by the US or China or could it do both?
