I'm looking for a way to build a 3D printer with fiberglass printing capability such as Markforged Mark One. I haven't seen any alternatives to that one, so I was wondering if there are any extruders out there that support fiberglass printing at all? Ideally I would order a kit and then modify it in a way to add additional extruder for fiberglass, but I'm not sure what option would be the most viable. Any advice would be greatly appreciated.
