Compared with capital investment costs of other machines for making plastic parts, 3D printers are already cheap, so I don't see price coming down as a huge player yet. Right now machine cost and part flexibility are the advantages that current 3D printers have in relation to other production methods. They will be, and are, used for production of one off custom pieces without precise tolerance and surface finish requirements.
