Beam Based vs Binder Based 3D Printing-a Critical Discussion
Metal powder based 3D printing technologies gain more and more interest in industry due to the general new possibilities Additive Manufacturing offers for part geometries and materials.Meanwhile different printing approaches have come up to fulfill different requirements in terms of geometrical aspects and material properties as well as to pave the way for higher volume production.Laser and Electron Beam Melting(LBM and EBM)which currently are the most widely spread processes for metal 3D printing are compared with binder-based processes as Binder Jetting(BJ)and Fused Filament Fabrication(FFF)which both are a combination of printing green parts followed by a sintering step to get usable metal parts.The sintering step makes BJ and FFF interesting for users of classical powder metallurgy production methods because the same heat treatment and the same post processing steps can be applied within production,only the initial forming process differs.Along the process chain,the paper discusses topics as metal powder materials and their characteristics to be used by the different processes.Details of the printing process and heat treatment as well as differences in further post-processing steps are shown.Possible set-ups for higher volume production are discussed.
