HICTOP Hotend for Bambu Lab A1 Series 3D Printers Bambu lab A1/A1 Mini Hotend with a 0.4mm Hardened Steel Nozzle and Silicone Cover

I needed a replacement nozzle and decided to go ahead and get the hardened steel this time. Easy install and fits perfectly. Prints just as expected! Solved the clogging issue that I was having and seems durable.

Easy install, stable temps, noticeably better surfaces Swapped this into my Bambu Lab A1 and it genuinely feels like a small upgrade over stock. The fit was true drop-in, wiring matched right up, and re-leveling took just a few minutes. I ran a calibration cube, then a 12-hour functional print and a detailed mini—edges are crisper and Z-seams less obvious. • Temp stability: Holds target within 1–2°C, even during long PETG runs. • Extrusion: Consistent flow; stringing reduced with the same profiles. • Maintenance: Nozzle swaps are straightforward; the silicone sock keeps things clean. • Materials tested: PLA, PETG, and a little TPU—no jams or heat creep. Pros • True drop-in for A1 (no mods required) • Steady temps → smoother walls and cleaner overhangs • Good build quality; threads/nozzle seat cleanly • Nice price vs. OEM replacement Cons • Didn’t include a storage tin or extra sock (minor) • If you’re new to hotends, watch an install video to avoid damaging the thermistor lead Bottom line: If your A1 is under-extruding or you want a fresh, reliable hotend, this HICTOP unit is an easy win.

Works and an exact fit.

Works well and just as advertised.

These work great.

Great replacement. Prints well. Fits well.

10/10 Accurate now all my prints look a lot better

One worked shortly then clogged, 2nd one clogged out of box. Normally i get months on a hotend, not days.

It works better then the original one
