I found a new set of nozzles that claims to be compatible with the SV06 ACE (and the Plus ACE, as well as the SV08 with the heatblock that takes separate nozzles). They’re from Durozzle, who I’ve not heard of before, and claim to be bimetal with a tungsten carbide tip and “copper alloy with nickel plating” body.
I was intrigued because the diagram on their site lists dimensions that do actually seem compatible with the ACE’s “slightly longer thread than K1 nozzle” spec:
So… I bought one on Amazon for $28. Not the cheapest for a single nozzle from an unknown brand, but if this nozzle works out as one I can use with abrasive and non-abrasive filaments and get good cooling / overhangs with the stock fan, it’s worth it to me. (Note: This isn’t an endorsement or recommendation! I still need to test it.)
I just got the nozzle and took some measurements, plus threaded it “cold” into the heatblock to dry fit. Dimensions look right, at least. Sovol brass nozzle on the left, Durozzle tungsten carbide nozzle on the right:
Threaded portion looks almost identical, and overall length is just slightly shorter than stock (much smaller difference than the Volcano nozzle). Here’s a couple more measurements:
I hadn’t heard of Durozzle before either, and at €30 it’s not exactly a bargain, but it looks pretty good. I had to Google it to find it, though. Thanks for the tip!
I have been trying a ruby nozzle from Durozzle on my SV06 Plus ACE and have been happy with it. It was $25 but seems to work well. I am not really using any abrasive filaments though but I like how clean it stays.
I’ve used other nozzles from Durozzle with my other printers and have been pretty happy with them as well.
Oh sorry, I didn’t want to link the Amazon page directly since I didn’t want to look like I was shilling for the brand, especially since I’m still debating whether I’d actually recommend it or not.
Initial testing: It installs without issue and seems to print fine, except that I continue to see overhang curling that’s worse than with the stock nozzle. I was hoping the length being closer to stock would address that, but the shape is still different, and even with the stock nozzle I haven’t been totally happy with overhangs, so I think it’s just the stock fan shroud that’s bad.
I printed out this new shroud from @cardoc (thank you for that, and sorry it took me so long to try it!) and will see if that helps matters. (Had some fitment issues I mentioned in the comments, but was able to hack around them in the slicer for now.) Right now I’m just waiting on some PicoBlade extensions (don’t feel like crimping something so tiny, and don’t mind having extra connectors on hand anyway) for the fan wire so I can properly test it out.
