Did people see that press release last week about an open source metal printer that only cost $1500 bucks and would cure all ills and bring world peace and so on?
Well, the original release didn't show any printed parts and the information on how the thing worked was sparse although it was clear they were using a MIG welder and a delta printer (with the delta inverted and the workpiece attached to the end effector).
I managed to find the academic article that details the work and here is the only thing they had produced at the time of publishing.
What do people think? - the guys who wrote the paper seem to think it's a viable means of making metal components. I aint' so sure...
