Olsson Ruby Nozzle for abrasive filiments
I was just wondering if anyone has tried using the olsson ruby nozzle on a Prusa... and if so how is it in printing materials like carbon fiber?
Anyone?
Re: Olsson Ruby Nozzle for abrasive filiments
Never heard anyone using it. Would it be bit an overkill?
Re: Olsson Ruby Nozzle for abrasive filiments
I have one., and it is overkill.
It prints very nicely.
I purchased it because I intend to use some abrasive filaments. Intend. I have not yet. I will let you know when I do.

Re: Olsson Ruby Nozzle for abrasive filiments
Is it overkill? I guess if you only print with PLA it is. I know nozzles degrade regardless of what filament you will use and if using abrasive materials it will degrade faster. I'm just wondering if this particular nozzle will hold out long enough to be able to use material like polycarbonate or carbon fiber to make it reasonably feasible. If the projects we turn out using harder filaments turn out well on a frequency to which we can use PLA currently, I wouldn't say that's overkill at all, I'd say that's the next step in printing evolution... am I wrong?
Please let me know how it turns out for you. Ok?
Re: Olsson Ruby Nozzle for abrasive filiments
I would say the Ruby is definitely overkill, IF you always print standard PLA and do not intend on doing any of the wide variety of metal filled PLA's or the Carbon Fiber. The only thing I would mention is that for any metal or carbon filled you can also opt for the hardened steel nozzle. I have a hardened steel nozzle I have been using for metal PLA, have not tried carbon yet, and it has performed great. In theory the ruby might have a longer life span but considering the hardened steel nozzle is less then a third of the cost of a ruby nozzle it is worth the trade off. Unless you intend on doing a tremendous amount carbon and/or metal printing I would not spend the extra money on the ruby, IMHO.
Re: Olsson Ruby Nozzle for abrasive filiments
If the nozzle enables me to use carbon fiber ( using an extreme here) for a decent amount of time and with accurate prints to make it more cost effective than steel nozzles, it will probably be the filament of choice for me. Don't get me wrong, printing nice figurines are fun and all, but I'm wondering about certain applications. My field of study is related to the medical field and making reliable prints that people can depend on, beyond just prototyping, is what I'm hoping 3d printing can one day achieve. If no one here has much experience using the ruby nozzle, than how about the steel one.
Anyone know the longevity of using steel nozzles with carbon fiber or other truly abrasive filaments for an extended amount of time?

I think you lose automatic bed leveling if you go ruby.

Why is that?

No, not true. But you do have to increase the temp by 5 to 10 degrees.
Personally I use the plated copper nozzles from E3D, plus a hardened nozzle for abrasive filaments. It's easy enough to change over.

Re: Olsson Ruby Nozzle for abrasive filiments
How does your copper nozzle fair with abrasive materials?
And for how long?
And are the prints accurate?
I would have thought copper would have been torn apart quickly because its soft.
Re: Olsson Ruby Nozzle for abrasive filiments
Ah I read that wrong... But my questions remain regarding the hardened nozzle this time. Lol
Re: Olsson Ruby Nozzle for abrasive filiments
The nozzle does NOT affect leveling. That is all done with the PINDA sensor.
The reason i purchased the Ruby - which I agree is not a requirement - is that I wanted to work with some of the harsher filaments, yet wanted the heat conductivity of the brass nozzle. This is the best of both worlds. In theory, the ruby should stand up to most any filament, and the orifice remains nice and round for nice prints.
I have not noticed a need for heat change - meaning the heat performance is similar. The extrusion calibration is about the same, which means the orifice is about the same. The prints seem better to me, but I think that is a combination of psychosomatic and my improved learning curve on slicer, printer calibration, and other things that have nothing to do with he nozzle. I have no time to go back and forth and do an A/B comparison, but I might later when I have time. For now, I like having it in, and the ability to experiment with filament whenever I want to try.
Is it worth the price? I think it is if you are going to do a lot of abrasive filament. I don't think it is for most of us (including me), but if you want to just not worry about it, it seems like a very robust solution.

So is there any particular steps I need to take to calibrate the new nozzle?

Nothing special with this nozzle. Just a calibrate z since it will be slightly different, and if you want an extrusion calibration (but I found it to be the same as my 0.4mm brass one.)

Aaron,
did you find the time to do a comparison? I'm considering to go for the ruby nozzle and would be interested in your findings...

Sorry, nope. The printer has been running almost continuously on projects 😀 I think the Ruby has printed very nicely and I am getting very nice surface finishes. Ironically, I my most recent projects are very large with very little detail and I put in a standard brass 0.8mm nozzle and am printing at 0.4mm layer height. Really speeds things up for these large prints!
I would say that I am very happy with the Ruby, and would recommend it if the price is not stressing. If you are very short on money, I think 4 new spools of filament are a better investment. I am pleased with mine.

Re: Olsson Ruby Nozzle for abrasive filiments
I use it on a different printer and it works really nice. Even brass nozzles do wear out with normal filaments, but they are relatively cheap to replace. I'm not a fan of the plated or stainless steel nozzles as I think they clog more often. Overkill, sure but really they are not THAT expensive for a $2000 printer, but maybe for a $300 printer.
Re: Olsson Ruby Nozzle for abrasive filiments
Ok, i just ordered and installed the ruby nozzle : 1.75 mm x 0,4 mm
I think the nozzle is the most important (but highly underrated) part in your printer... it's the part that has the most contact with your prints and filament...
Short : is it worth it ? YES !!!
Why ? Well, carbon fiber 0,5 mm wear print test shows :
Brass, 0.3kg carbon fiber filled filament printed.
Stainless steel, 1kg carbon fiber filled filament printed.
Hardened steel, 4kg carbon fiber filled filament printed
The Olsson Ruby, 8kg carbon fiber filled filament printed : No wear visible under microscope
Theory : you buy one roll off carbon filled pla for 50 bucks and order 3 brass nozzles with it and in between prints you can , unload , replace and calibrate your nozzles and have a high risk of ruining your prints... remember your brass nozzle has 0,5 mm wear after printing 0,3 kg carbon pla.... Not so nice if you need 0,05 mm z-layer precision
Or you just fork over the 100 bucks , get over it , and just go on printing and forget about replacing nozzles , calibrating and ruining prints ever again...
For me it was a set and forget situation, i replaced my old nozzle and did not even have to calibrate, just printed first test layer and was very good.
Although it is same 0,4 mm it shows more detail (thinner lines) so you might need to up the extrusion a bit.
I use simplify 3d and just upped the extrusion multiplier to 1,2 to get same extrusion width for now, since it gives thinner lines i'm going to experience with smaller nozzle size setting (0,35 for instance)
I also own a leapfrog creatr but love my prusa MK2 (not s) , good results, auto hight and geometry calibration (pinda) is just awesome feature.
Only thing i don't like is ringing and resonance artifacts in smooth prints, the prusa drivers/motors make a rough motion....
Next i try some stepper smoothers if i have time
Re: Olsson Ruby Nozzle for abrasive filiments
One other thing to consider when you switch to ruby is that the threads are slightly shorter than the E3D nozzles. That means you need to get the heatbreak slightly deeper into the heater block to get a good seal an prevent leakage out of the top of the heater block. Otherwise you get all kinds of nastiness happening, especially with hotter filaments.
Re: Olsson Ruby Nozzle for abrasive filiments
I'm using one - and have been for a while,
I print a fair amount of metalized (PLA) and carbon fiber filaments (Weapon of choice being colorfabb XT CF20, but generics as well).
On my printer before my original prusa i3 Mk2 I was using an e3d v6 hot end and hardened steel nozzles but found you had to temperature compensate for them 5-10 degrees and they still wore out after a few rolls of carbon fiber reinforced filament. While the hardened nozzles are cheaper than the olssen ruby (and brass even more so) the cost for me isn't so much in the nozzles but in the failed prints (dimensional drift, under extrusion or total fail due to clog) as the nozzle wears out on the inside (changing the bore) and down (changing the Z). Add to that there's always the concern you'll slip on a nozzle change and - as you have to do it while it's heated - get burned or worse, stuff up the heater cartridge and/or temperature sensor wires potentially dead shorting the heater cartridge in the process.
Even not counting my ham fisted antics with spanners causing collateral damage during a change, the Olsson pays for itself over time if you're printing abrasive filaments. You can rely on it to not wear (I'm still on my first, after several rolls of metalized and carbon filaments it's still printing just fine 🙂 ), there appears to be little to no temperature compensation required from a standard Brass nozzle and I get less print failures from my 0.4mm gradually turning into a 0.8 🙂
if you're just printing PLA, ABS PET or standard Nylons .... sure it's overkill. But if you're like me and one of the drivers for buying a Mk2 was to print exotic materials, it's money well spent. (and boy - the spitfire that comes with the Mk2 looks cool in carbon 🙂 ).
Putting my money where my mouth is, I'm about to pull the trigger on another Prusa Mk2 to clear my idea backlog - and guess what I'm swapping the stock Nozzle out for during the build 🙂
..... and no, I don't work for Olssen and I don't sell the Ruby nozzles.
Hope this helps,
Cheers...
