Announcing: E3D Volcano - Print Faster, Stronger, Bigger.
A super high flow add-on pack for E3D HotEnds. Cut print time in half. Dramatically boost print strength. Print big stuff fast.
Much plastic, very extrude! Wow…
We have been doing a lot of tinkering with various slicers which actually behave shockingly differently with such large nozzle diameters… Will do a blog post on findings soon!
Oh gawd, the logo! (cue immature giggle)

But as always, nice work! The incredibly huge printers i saw at Euromold were also incredibly slow - this is exactly what they need. Most of them were still printing with 3mm, i assume that’s because that size is more commonly available on the big 2.2kg spools. Any plans on adding larger spools to your shop?
I TOLD YOU THEY WOULD SAY IT LOOKS LIKE A DICK @Gabby_Tymkow GODDAMMIT.
First comment too. Nice. You’re supposed to be a grown up with a job now @Thomas_Sanladerer !
Will chat with our supplier regarding larger spools, it certainly fits with Volcano. We chewed through a kilo of PLA in the first 2 days of testing.
3mm really doesn’t make sense for a high flow nozzle. I think a lot of this is because intuitively people think bigger machine, bigger nozzle, bigger filament. Almost the opposite is true in reality.
That’s nice and all, but WHAT’S THAT PRINTER OMG
Also huge tracts of… filament.
@Sanjay_Mortimer1 of course, it’s also called the eruption pack…
1.75mm likely makes more sense here, but not because the surface per volume is greater - the surface in contact with the heater is at any time (roughly) only half as large as with 3mm. And you’re feeding three times as fast, but the heat also has a lot less depth to penetrate through plastic. That, I think, makes the biggest difference here.
I feel like you release parts just as I’m about to complain that no one makes them… like a 3D printing wizard.
I REALLY hope I can talk my wife into getting this for me for Christmas! 
Excellent machine to make Cosplay Props
Ordered eruption! Let’s blow through some filament!!
@Sanjay_Mortimer1 I’m curious about maxing out one of my smaller machines with this extruder. Do you suggest upgrading the extruder drive motor when doing high flow printing? This one I believe is a Nema 14.
I think you are correct Tom- when testing the Volcano to the limit of it’s capabilities, in 3mm with a 1.2mm nozzle the extrudate was noticeably cooler at the core which is something that only happened at even higher speeds with 1.75mm filament.
@Thomas_Sanladerer true! A smaller filament diameter is better than slowing down, increasing heating power or increasing the length of the thermal transition, which all have annoying drawbacks imho. Had some trouble with my 1.1 mm years ago and I think it was the issue
Have it been tried with a dual setup, say with one 0.6 mm nozzle for perimeters and one 1.2 mm nozzle for infills on every second layer?
@Terje_Moe I think I was told that some slicers already supported this (Cura’s engine most probably), but I have never seen any actual results so far
My extruder feels inadequate now.
