2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab

I bought these for the A1. So far compatibility and performance have been identical to the original nozzle with no change in accuracy or layer lines. Everything heats up correctly and installation was easy. I can't speak as to durability since I've only completed a few print jobs so far.

The perfect spare parts. The fit perfectly. And we have had no problems with printing.

So as everyone knows, there aren't any profiles for the Kobra 3 Max for larger nozzles than 0.4mm. However, it didn't take much to get these going. So far only used the 0.6mm and the prints are silky smooth even at 0.3mm layer lines. The nozzle outperforms the stock one in quality imo. I go through a kg of filament every few days so they get used quite a bit, but not a farm or anything just a hobby. Rare stringing, getting speeds around 80-100mm/s but still shaves off 1-2hours a print easy and more on even larger prints. Here are the settings I use in Anycubic Slicer Next Don't forget to go into printer settings on the actual printer and set the nozzle to 0.6/0.8. This will cause it to do a vibration calibration and PID for the new non-standard nozzle. If you don't do this it won't match the slicer profile and won't print. If you are wanting to do the 0.8mm nozzle just change the line widths to 0.82 and the two other options to 0.85 and then layer height 0.4mm plus the rest of the changes. Each new item that is different than the previous print I do a calibrate flowrate from the touch screen so don't even mess with the volume 11-12 in the settings that can be adjust but might be useful to avoid calibrating. Only have to redo it on spool/color change Process: Advanced on Layer height: 0.3 First Layer and Layer: 0.3 You can still use finer lines and could do 1st layer 0.3mm and Layer after that as 0.1mm. Which still prints surprisingly fast. Line Width(s): All 0.62 Except: First Layer 0.65 Sparse Infill 0.65 Precise Wall: Enabled Printer Settings: Basic Information Tab Support Multi bed: Enabled Z offset: -0.02 Extruder Tab Nozzle Diameter: 0.6 Layer Height limits: 0.1/0.3 (Min/Max) Wipe distance: 5 Filament Profile: I'm using PETG so just adjust the temps or whatnot. You want to bump your temps 5-10C at the nozzle Cooling: No fooling for first 5 layers Full fan speed at layer 6 Part Cooling Fan: 10/100 (Min/Max) Keep Fans always on: Disabled Don't slow down for outer walls: Enabled This keeps the fan in use only when needed and at a rate it calculates. Since with PETG you don't want a lot of fan. Settings Override: Retract on layer change: Enabled Wipe while retracting: Enabled Wipe Distance: 5mm Retract amount before wipe: 0 Sorry for no images, not a fan of sharing any IRL photos on the internet.

These fit and perform just like original product, fit was perfect with no heat issues. set comes with silicone nozzle sock and the best thing is price and how fast you can get the items. I have used other products from this maker, and all are a solid replacement option. Don't be afraid of trying, have used these for lots of prints and they produce exactly as expected. Each nozzle seems to be exactly like the oem can't see any difference and had to change nothing on printer, installed and went back to printing.

I DO NOT RECOMMEND!!! Nothing but problems i recommend sticking with original nozzles from bamdu or a known manufacturer gives me problems when homing clogs on nothing almost like the filament is cooling in the nozzle

No difference between these and oem nozzles. I always buy these for all machines and never had a problem. I have purchased dozens. Dont drink the tea, these are far from complicated. Stop paying more for a name!

These nozzles perform just like the original, but they are hardened steel, making them suitable for fiber materials. I don't plan on printing with any of the engineering fibers, but it does not hurt to have the ability. For the cost, they are excellent. Don't waste your money on "official" factory parts.

using it with bambu A1 mini, performing better than the one came with the machine.

Top Qualität und Preis Leistung stimmt einfach alles.

Absolute Waste of money, after 2-3 hours of printing both my printer has clogged extremely and had to change the Hotend Heating Assembly to fix the printer costed around 5-6k

J'avais besoin de changer les ventilateur de ma X2 et je susi satisfait.

Revising this, if my other one went through. The heads are working now, after rigorous cleaning from their (both) initial clogs, but now, I'm printing on the .4 nozzles and both of these at the moment are working on par with the original Bambu one.

Se rompieron los ventiladores originales y compré estos, el ventilador de turbina hace un poco más de ruido pero soportable. Como recambio lo recomiendo a falta de ver su duración.
