The Create Doodlepad IS NOT compatible with Flexy, Wood or Metal.
Note that these filaments will leave residue on your DoodlePad. Masking tape will get most of the pieces off, but using them may still damage your DoodlePad.
You can use the Create DoodlePad with all other PRO filaments.
Please ensure you are not using the 3Doodler Start DoodlePad, which is not compatible with the Create, the PRO, or their accessories. You can reference the compatibility chart here to make sure: www.the3doodler.com/compatibility
