I’d like to thank those that helped me to make sense of it all. As well as my own knowledge, I’ve used interviews with end-users of systems, resellers, and researchers to guide my choices and wording here. This guide is meant to be a helpful aid in orienting you on market movements, relative criteria, and merits of systems. “Best” probably depends on what you want to make when, about as much as the system itself. This is meant to be a good general starting guide for people who want to know what the relevant developments are in metal printing and what are some of the most recognized, prevalent, and deployed systems out there. This is due to the fact that these industrial solutions will all excel for different parts, materials, customers, and applications. I don’t believe in top ten lists or a dutiful “defining of the best” for many things. These consist of laser powder bed fusion (L-PBF), electron beam powder bed fusion (E-PBF), directed energy deposition (DED), and bound metal printing (BMP). In metal AM, there are a few main technologies that are deployed today. According to the Additive Manufacturing with Metal Powders 2020 report from SmarTech Analysis, hardware revenues have increased almost threefold over the past five years and material sales increased close to six-fold. Metal 3D printing has seen a lot of attention leveled at it over the past several years, with the metal additive manufacturing (AM) market seeing real growth over the past decade.
