I wanted to get a Bambu A1 Hardened Steel Hotend to print glow–in-the-dark filament, but the shipping was half the cost of the product itself! Has anyone found any luck with cheaper, off-brand A1 hotends? If so, could you let me know?
If you want to cast a broader net, the A1 can use the same nozzles as the H2 series.
I bought two new unopened tungsten carbide hotends on eBay and have been running one on my A1 mini with zero issues for months.
