I don’t understand your second question — they printed a bunch of martensitic steel tensile specimens with a pretty common laser melting technique, then ran a bunch of mechanical testing. Where’s the lack of execution?
I think the art/science thing is just a bit of editorializing, it’s sort of accepted that a lot of the fundamental science behind metal additive manufacturing is just not established. I.e. it’s far from trivial to just set up shop and print an alloy that hasn’t been printed before.
- JoeAltmaier 7y agoI read it again. They 'developed a framework'. I'm thinking they 'printed' a few microscopic samples in a lab? A real printer could print a car hood, or at least a gear. If they didn't get that far (with all the associated problems of delamination, gaps, vibration defects etc) then they don't have a real 3D printer. The 'art' is in the delivery.
