High temperature resistant material for MK3S upgrade?  

RE: High temperature resistant material for MK3S upgrade?

I'm not surprised if you have to bump temps on the Ruby Nozzle as it has poor thermal conductivity.  Even the Nozzle X needed a temp bump but I've since gone TC and would not go back.  Also use a mosquito hot end.

Have you tried another nozzle?, the more I read about the olsson ruby, the more I'm inclined to stay away.

No I haven't. The only other nozzle I have at the moment is a 0.25 mm, and there is no way I'll try to push PA-CF through that one.

However, it seems that I was balancing right on the edge with 280℃. Printing the same part (with its several retractions) at 275℃ works without problems, and layer adhesion is definitely better than at 265℃.

Forgot to mention that I am quite happy with the ruby. It doesn't give me any trouble other than a couple of materials where I have to add 5-10 degrees to the temperature (PA-CF being one of them). Most materials don't need this. I print PLA, PETG, ABS and CPE-HG100 with Prusa default profiles.

I enjoy the convenience of not having to swap nozzles whenever I want to print abrasive materials.

And that is why I love my TC Nozzle, no swaps needed + has the thermals of Brass!

For those of you using/printing carbon fiber, have you noticed any difference in interlayer bonding strength? Or is it still PLA?

No difference for me

RE: High temperature resistant material for MK3S upgrade?

My interlayer bonding strength is great on all materials incl PA-CF and worked out of the box from day 1.  The only exception for me is PC which I've yet to spend the time to work out if it is my profile, filament etc.

I really need to pull the trigger and get a TC Nozzle. Do you have any brand recommendations? I've looked at the DyzeDesign and I wonder about the internal geometry because of the insert. Ev3DM doesn't seem to be available anymore. Spool3D is single piece TC, but expensive. Have I missed any?

Granted, I'll then have to upgrade my MakerBox subscription from Easy to Everything... 😉

RE: High temperature resistant material for MK3S upgrade?

I have both the Ev3D (which has been out of stock for age now), and recently received the Spool3D in 0.4 to compare.  I think the Spool3D is a better match for the profile and size of the std E3D nozzles.  Both print well.  I've also got a Spool3d in 0.8 that I've not yet tried.  I would not touch the 2 part design.

RE: High temperature resistant material for MK3S upgrade?

I ordered the Spool3d - waiting for delivery.

+1 for the Spoll3D TC nozzle. Here I compare one of mine with a E3D brass and EV3D TC nozzle. Also, I don't know why one would opt for a two part nozzle when a single part nozzle whose entire composition has good thermal conductivity is available.
