FAQ
Q: Will the joint clog my nozzle?
A: When done properly, the joint is smooth and feeds through standard nozzles. Trim any excess material at the joint before loading.
Q: Can I join different materials together?
A: Best results come from joining the same material type (e.g., PLA to PLA). Joining different materials may produce a weak joint.
