yeah, you can't replicate printing in zero g unless you are in zero gee.

It's not like the experiments growing plants under zero g where they grow them in constantly rotating environments to confuse their sense of gravity.

You'll never get the kind of over and under hangs you can get away with in null g environments.

Plus the guy in holland who builds the rails for ultimakers to print huge prints upside down - did this some time ago :-)

Guess it's fun - but ultimately completely pointless ;-)
