I really wish that we could replace the phrase &quot;3-D printing&quot; with &quot;additive manufacturing&quot; when referring to metals and&#x2F;or serious, low-tolerance manufacturing.<p>&quot;3-D printing&quot; should be used when referring to hobbyists making semi-useless, plastic trinkets. No disrespect to plastics or hobbyists, it&#x27;s just that the phrase lost some dignity when it became a over-generalizing buzzword.
