Looks like first 3D printer on the vomit comet too!

It looks just like every other cartesian printer, but with stainless sheet metal on the sides. I wonder what challenges they're talking about with microgravity. And I wonder how much they spent to make that thing and get it into space...

If it's going into space, I suspect it's mostly Titanium for the strength/weight ratio. When you factor in the $10,000/pound to get it into orbit, it's cheaper than steel.
As for lack of gravity, that means no natural airflow. Heat can't rise when there's no up. That also means adhesion is the ONLY thing attaching the object to the bed. On the up side, it may be possible to do some truly great prints without any supporting structure at all.

no gravity = no air currents. cooling fins don't do anything if there is no air flow.
Granted there will be some air flow because the air is always recycled in the station. But it might not be enough to cool parts that are 200C.

awesome. now we just need a buckyball filament and we can print our very own bean stalk!

Have Gene document how to build that, I guess you would turn the instructions upside down?guanu wrote:gravity what?
