We have two (2) Prusa MK4 Printers that are both capable of printing multiple colors (up to 5) at the same time allowing for all kinds of flexibility in terms of what can be printed. 

Our Glowforge will cut or etch almost any surface. We have a number of plastics (multicolored) and wood products that can be used in the Glowforge. You can also use cardboard as a great way to try out ideas and do test prints.
