3D printer pens and FDM 3D printers both use plastic monofilament, PLA being the most common. What diameter of monofilament and what material your 3D pen can use will depend upon the 3D pen itself, what settings it has and the nozzle size.

For instance we had a customer try out our 3mm ingeo PLA in their 3Doodler 3D pen.
