I just refreshed on a lark and ordered two high flow nozzles. Heads up in case anyone else has been waiting to order.

I tried too and missed it. I guess they restocked like 10 of them… 
I just got lucky haha. Sometimes obsessively refreshing webpages can be a good thing ¯_(ツ)_/¯

High flow was out of stock 3 hours after I got the notification email. There are not that many H2Ds in the wild, so Bambu’s problem with producing accessories is confusing.
Their lower cost machines must be selling well and soaking up capacity
It is confusing, there aren’t a ton if H2D machines in the US, and how many of those owners just happened to be online at midnight?
I still want a set, but after testing them in the slicer I’m not all that heartbroken to keep waiting.
I am just happy I got some extra silicone socks today for the H2D nozzles I ordered weeks ago.
I mean I would assume a few thousand US H2D orders at least if you include all SKUs, and a lot of people are going to want 2 nozzles. I purchased 2 HF nozzles and right now they’re just sitting next to my A1 nozzles waiting on the printer. Combine this with tariff induced panic buying and the fact that Bambu is probably hesitant to import large quantities of anything right now and I can totally see a few dozen people emptying out a barebones stock really quickly

Looks like they are taking orders for High Flows with an expected ship date next month.

… and they’re sold out again!
I wonder how long it will be before there are aftermarket nozzles available, like the many there are for the X1C.
Yea, I’m waiting for Diamondback nozzles for the H2D. I love them.
The diamondback nozzle are standard flow, not high flow so you dont get the benefit of stronger layer adhesion. Also they also have some problems with GF filament.

Yea I haven’t run Diamondback on a Bambu printer yet, but have loved them on my other printers. I print of a lot of CF, glow in the dark, and other abrasive filaments. Their nozzles are incredibly durable.
For sure, I print a lot of CF and GF filament as well and I am yet to wear out a hardened steel nozzle. I rather have the stronger layer adhesion for better part strength and swap the nozzle when it wears out. I had 8000 hours on my X1 and P1 and the obxidian HF hot end was not worn out.

I agree on the layer adhesion side, definitely more important. On non-bambu printers I’ve got nozzles over 2 years old that still look brand new, but they didn’t suffer from adhesion issues.
It will be interesting to see what third party options show up.
Its not that the standard flow nozzles have bad adhesion, its just that HF nozzle have better adhesion especially as you print faster. When im printing functional parts, I want the best part strength possible. On printers that print more slowly its not as much of an issue.
I dont think we will have a ton of aftermarket hot ends as the OEM Bambu HF is very affordable and good, will be very hard to beat it for price/flow. Also not easy to make an A1/H2D nozzle as its quite compact, companies like micro swiss wont be able to fit a V6 style screw in hot end in there. Im sure Phaetus will come out with one as they have it for the A1 already and it will require minimal redesign to adapt it to H2D. I would not put that type of screw in hot ends in my H2D, as there will be an internal joint and that can cause clogs.
