In 2018, the space sector grew to an incredible $3.25 billion industry. A number of different technologies are driving this rapid growth, but the most promising one is industrial-grade 3D metal printing (a.k.a. metal additive manufacturing). Once met with skepticism, 3D metal printing has proven itself to be a cost-effective and efficient way to develop production-ready parts, making it the new darling of the commercial race to space.
