Well just another reason why I regret buying this printer. Have been having nothing but frustrating issues from day 1. About gave up a couple weeks ago and tossed this into the trash but I decided to spend another 2 full days of wasting filament. Decided to check every screw and found something very interesting. I found filament leaking out the back of the nozzle housing. So I heated up the nozzle and removed it from the housing and found that half of the brass nozzle was rusted. Now if its brass in a copper housing how does it rust like this? All parts are original sovol products and nothing aftermarket. This was a nozzle I bought when buying my printer from sovols website. Anyone else experience this? Im seriously at a loss right now and feel like I have been scammed and have just wasted so much time and money. Just wild. Let me know what yall think. Thanks.

Very surprising cause brass cannot rust.
Depending on atmospheric conditions, an oxide layer may form and that’s it.

Yeah I was surprised to. The printer is also in an enclosure and my place stays at 55% humidity. So not sure how this could have happened. Also this nozzle and the housing is less than 1 month old.

So clearly the nozzle from sovol is not brass if its rusting like this. Ill probably get the wire wheel out later and clean it up to see whats under the rust

Interesting theory but if you look at these pics you can see where filament has leaked out so I’m wondering if that had anything to do with it.

HAHAHA was just looking at the other failed and broken parts from sovol that I have and looks like that leaking is what caused this catastrophic failure. You can literally see the river of filament flowing out from that joint in the pic.

Why don’t you email SOVOL with your order number?
You can request a new complete extruder if you explain your case.

It’s not rust..it’s caused from the filament fumes from your leak.

That’s what I think too, but it’s always the printer that’s involved

Silks can leave a nasty residue.
That’s going to be hard to get clean, you should just replace it.
If the block looks like that inside also, it could happen again or give you heat creep…
It’s best just to replace the whole setup, nozzle, block & heatbreak…JMO
