I shouldn't worry, 3Doubler - Minmet is just the Chartist's major longterm obsession. The rest of us who got it wrong wrote it off to experience years ago.
Minor obsessions include the fact that PIM stands for powder injection moulding - although sometimes it also stands for plastic spray coating, and might even be the current acronym for boring old rat shit? Then there's the fact that PIM is not new and has been used for years, and all the recent patents are just old stuff recycled. Oh, and don't forget the one about "no-one will want plastic fences, houses, sewage pipes, roofslates, truckbeds, scaffold boards, manhole covers, boats..." in spite of the fact that 3DM have been asked to make prototypes of all of them and have licences signed for fences, houses and boats. And the photos on the website are of products made by someone else and are nothing to do with 3DM. As for the alpha machine, it is a figment of the imagination, and the automated beta now at Trowbridge is just any old demo machine.
If I were you, I should just do what the rest of us have done with his garbage - filter it.
