Additive Manufacturing(AM)has emerged as an attractive technology for forming 3D parts without the use of any tooling.Although polymer 3D printing has become a mainstream process for forming plastic parts,metal AM technolgies have not yet received the same level of adoption.Presently,metal AM is dominated by powder bed fusion technologies,but high finanicial barriers to entry,high unit costs,and specialized powder requirements have limited their growth.In contrast,metal injection molding(MIM)is currently a mature metal forming process,capable of utilizing a large number of different materials.Desktop Metal(DM)is currently developing an additive manufacturing technology,Bound Metal Deposition TM(BMD),that leverages the MIM process.By doing so,BMD holds the promise to remove the obstacles limiting the widespread growth of Metal AM.This paper presents the current state of the technology and describes the similarities and differences between BMD and MIM.
