Although you *can* print gallium alloys at room temperature don't put the resulting objects anywhere near bare aluminium or you will be sorry.
It is a lot more reliable to print things using a variant of the lost wax process to make a mould and then cast in conventional metals.

I wonder if you could make a metal object using the 3D printing technique by electroplating? Bit slow, perhaps.

Yup. Doing it with hot metals is difficult, dangerous, and leads to a lot of badly warped parts when you're done.

I've always wanted some of those low melting point indium/gallium alloys.
Hmm can't find a price. George H.

Try this instead...
...I mean, what could possibly go wrong?

Roughly $300 /kg for Gallium. Keep it away from aluminium and follow the MSDS. Indium content dominates the eutectic price these days.

Does "bare aluminum" exist in the real world? If it does, it's not for long.

Watching gallium chew its way into aluminum is pretty amusing. Happens fast. Gallium is also inconveniently reactive--it scums over like molten solder.
