with the prints where you get an stl file with seperate parts. Most slicers will let you 'ungroup' them and turn them into seperate stl files that you can then print seperately.

But - yep I would say that the larger the build volume you can affor the better - up to a point lol

Large volume cheap printers will have rigidity issues. Likewise some of the large I3's that don't have z-axis bracing will struggle.

But yep, make the effort to buy a machine that will do what you want.

@matt have a look at tenlog IDEX machines: https://www.amazon.com/TENLOG-Indepe...9704798&sr=8-3
you can use soluble supports in one extruder and anything you like in the other. Has 300c hotends for some of the more esoteric plastics.
And a build volume 300*300*350mm /11.8''x11.8''x13.8'' - over 4x the build volume of the voxel.
And just the best mechanical design i3 currently for sale.
