How to compare 3D printers
Start with what you want to print: the materials rows say which each printer handles as it comes, and which need a hardened nozzle or an enclosure first.
Then decide on colours (a multi-colour unit, in the box with a combo or bought later) and size: the build volume is the biggest single part it can print.
