Yes! The Flashforge Inventor II(s) will extrude any 1.75mm diameter PLA 3D Printer filament. As with any printer or filament, mind the golden rules - cheaper is not always better, and filament that gets old/moisture laden will exhibit very odd printing behavior. 


The spool well in the back is designed to be used with PLA filament directly from Flashforge. More can be purchased at the websites below.


To utilize other larger/smaller filament spools, print your very own spool holder! This one is designed to mount off the back of the printer, using pre-existing screws. All you'll need to install this is a Philips (+) head screwdriver. We recommend printing it at 40% Infill or above for a nice strong print.
