Bambu Lab 0.4mm Nozzle CHT Hardened Steel High Flow Nozzle for Bambu Lab X1/X1C/P1P/ P1S 3D Printers 2 Pieces

Worked great on my Bambu P1S and just bought another setup for my X1C. Basic PLA flow rate tested up to 40 mm3/s with 0.6 nozzle and could go higher but my test print topped at at 40. Used with a XIFOWE hot end I picked up on Amazon. Stock Bambu harden steel 0.6 mm nozzle only achieve ~30 mm3/s and quality not as good as this nozzle at 40. Have run several larger prints at 30-35 mm3/s with great results, plan to push it closer to 40.

Uneven extrusion. Works well when the nozzle is in the air, but when you go to print, it comes out in globs. Tried all temps 200-240c PLA. I suppose if you wanted to print at 30mm/s, it would work. The piece in the middle isn't sharp enough, I think is the problem. Get the $21 one from bondtech. You get what you pay for, it's crap.

I would buy again. I had a uhf adaptor that kept leakin with other nozzles. Slapped this in and no leak! Even swapped out old nozzle on other printer after how well it was puttin down plastic. Would buy again, ideally in a .6 nozzle.

These work great for me and allow me to I crease speeds and volumetric flow rates. No issues and the price is good for 2 nozzles

I needed a replacement cht nozzle because my last one clogged while printing with CF. Make sure you recalibrate flow after installing. My flow values ended up being 0.045 but it may differ from printer to printer.

Junk, you have to run at very high temperatures for it to work!

Coupled with a melt zone extender and volcano adapter you can reach 30-40mm/s3. These print well and worth as expected.
