Original Bamboo Lab A1/A1 Mini 0.4mm Hotend,High Temp&Fast Speed Hardened Steel Nozzle+Heating Block Integrated Structure Hot End Compatible with Bambu Lab A1 and A1 Mini 3D Printers

Easy to replace the old nozzle with this one. Seems well made. Have not run into any issues so far. It got us up and running again quickly.

My PC filaments kept clogging in my .4 hotend so I grabbed this for those thicker filaments. It's OEM so it fits and functions perfectly. I bought spares in every size that are all OEM so I don't have to worry about quality or performance.

Works well

Plug and play, simply pop it in, change the setting for the machine and go! Great nozzle for doing faster prototypes, it really cuts the time down compared to the .4 nozzle while delivering as expected. If you want multiple nozzle sizes for your A1 Mini (what I have) or A1 I really don't think you can beat the price on this. While I still print the majority of things with a stock 0.4 nozzle, I'm glad to have this as an option for larger prints.

This is an official A1 hotend from Bambu but the price is double what Bambu charges for these, though they frequently sell out. Even selling out, I feel it’s hard to justify the heavy price increase for this.

I am not sure there is much to say about this nozzle. It is an OEM Hardened steel nozzle. Great addition to my A1 mini. I have already upgraded the extruder gears on it so I am now able to print using more exotic filaments. I use the external spool when printing these filaments so that gears on the AMS lite don't wear out too much. I do prefer to use a .6mm hardened nozzle for the filaments with more additives to prevent clogs but now I am using the hardened steel nozzle as my main one. It works great as expected. It is also so easy to change nozzles on the A1 mini that it is always a great idea to have extras on hand.

Always nice to have an extra hot end, I didn't want to use it yet but packaging and quality looked good. No complaints from me.

Did not work with my A1 printer. Squished the first layer. Not sure why as it is a genuine Bambu Lab part. Attractive finish but went back to stock nozzle.
