Filament

There are more filament manufacturers today than one person can reasonably keep up with. This is my list of suppliers and manufacturers below that I recommend based on personal experience. I’m in the New England region of the northeastern United States. Availability and suppliers vary widely around the world, so be sure to check into local sources.

Please remember there are cost-effective filament sources that are competitive with Amazon on pricing and even shipping. Be sure to check out the suppliers and manufacturers that directly support the 3D printing community before ordering.

Note

These notes are based on my experiences with the Prusa i3 Mk3 printer. If you are using a different printer, please verify the hardware details are same. These pages may be a bit rough as I revise them and add new material. Please check back regularly for updates.
