Comparing additive manufacturing processes for distributed manufacturing

Additive manufacturing (AM) has been considered for distributed manufacturing. However, the consideration usually concerned AM in general, not specific processes. This paper will look at properties of different processes from perspective process and materials, post-processing, requirements devices spaces, raw materials. The findings show that powder bed fusion binder jetting pose challenges material extrusion (MEX) can be affordable a form. It would ideal option when demand parts is low. VAT photopolymerization similarities to MEX but slightly more expensive demanding post-processing phase. it scaled up higher production rates higher.
