Someone needs to change that so it says " you could download a car"
Those legs look sharp.
Besides, the real question we should be asking is if it’s food safe?
I don't understand exactly what is novel about it. Maybe this is just another round of MIT PR doing it thing. Remember media publishing that MIT developed solar cells that also create energy during the night? Yeah. µW as they used heat stored during the day ....
Back on topic: Those machines are already in production environments. Most of them opt to use metal wire and laser (some an electrical arc similar to welding) instead of a molten material but they are more or less identical. If you go back a decade you will find people in the RepRap forum experimenting with solder wire as filament for FDM. To completely blow your mind: there are commercial printers available that do extrude liquid glass.
All metal is liquid under the right circumstances.
Interesting. At first I missed the video. They "inject" the alumninium into the sand by pushing the nozzle in. A pretty neat idea really.
Presumably it's going to be patented though, so it won't benefit many people for the next 20 years.
