A range of different technologies are in use by 3d Printers. What is shared across all 3d Printers is their basis in additive manufacturing. This videos explains the different types of 3d printers.
In this video, I'll compare two outstanding printers at different price points. The Original Prusa i3 Mk3 that sells for $750 as a kit and $1000 fully assembled to the Monoprice Ultimate 2 that sells for $500 fully assembled.
Are you looking to try out 3d printing? Maybe you're a new retiree looking for a hobby, or a mom or dad looking for something to engage your kids with that doesn't involve video games.
