Just for the record, 3D printers are probably going to get less and less expensive in the future. When normal printers just started getting made, they were over 1000 dollars. Now it's cheaper to get a new printer instead of getting new ink and toner. So just give it a few years.
I know, now normal printers cost people around $100-300, they used to be a lot more outrageously priced; now they're affordable at least.
Our school has had a 3D printer for a few years now.
Are they used for design or art classes of some sort?
