Nozzle Type Advice?

Hi

I'm sorry if this has been posted before in here, I am seeking advice about nozzle type as I am planning to order extra nozzles for my printer. As I know, there are about 4 types of "cheap" nozzles out there excluding ruby nozzle, that is brass, hardened, stainless and copper type.

I don't really know it's "hidden" differences except that stainless mainly for food safe or something, hardened is mainly for harder material like copper and carbon type filament while copper is for higher temperature up to 500'c.

I forgot where did I read about these "advanced" nozzle (either hardened or stainless) may prone to clogging or the plastic won't extrude properly during printing.

Planning to switch to a nozzle that may not get damaged or wear due to normal printing. I often prints in ABS as PLA are bad with the stainless heatbreak.

Any advice are welcomed =)

P.S

I would like to add the so called "titanium alloy" as well

If you only print ABS and PLA without addtions like wood, carbon, glow in dark and others, the brass nozzle is the best for you.
Otherwise if you print hard materials even if PLA you need a hardened nozzle, or brass will wear in few prints.

Ruby nozzle is a general purpose nozzle, can print any material, it have the benefit of the brass nozzles and a rubby tip to prevent wear. But not use for food safe.

The copper nozzle have a good heat transfer, but will oxidize fast.

So for most of the people the brass is the best to go.

Titanium Heat Break will block the temperature better, this is not required, only if you want to print very high temperature things like PEI and others >300ºc

Aditional information can be found on e3d website under product, eg: Copper plated: "Durable, non-stick, high temperature performance nozzles. This copper alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature 3D printing that other nozzles can't handle. These nozzles are fully integrated into the E3D Ecosystem and will fit V6, Lite6, and Titan Aero HotEnds, and are compatible with Prusa 3D printers."

Stainless steel:
"Medical grade and food safe stainless steel nozzles. Print slow! These nozzles are fully integrated into the E3D Ecosystem and will fit V6, Lite6, and Titan Aero HotEnds, and are compatible with Prusa 3D printers."

hardened:
"Hardened abrasion-resistant nozzles developed to last a lifetime. 3D printing with abrasives such as carbon fiber, glow-in-the-dark PLA or even filled filaments like woodfill all take their toll on a standard nozzle. These nozzles are fully integrated into the E3D Ecosystem and will fit V6, Lite6, and Titan Aero HotEnds, and are compatible with Prusa 3D printers."

Still there should be a comparsion table for users know the bads and good things about the nozzles

If money is not a problem and you like to print some abrasive materials from time a time but don't want to exchange nozzle everytime the filament requires the rubby is the best

Re: Nozzle Type Advice?

But ruby is brittle so if you like stuffing accupuncture needles up your nozzles. Perhaps ruby will not last long..

So far I have never stuffed an accupuncture needle or drill or similar, up my nozzle...

(Bet I get a clog that I cant shift. Now)

Well, even on e3d site about the material guide, just the general property of that material and contrast usage of it.

What I planned to do is to get different sizing for the brass for detailed print and will go back to a regular printing nozzle maybe either stainless or titanium with about 0.4mm.

I don't really get it about the stainless steel nozzle "print slow" thingy though.

stainless steel has low thermal conductivity. This makes it more difficult to push energy into the nozzle tip, especially because the controls were not tuned for this material. There is a good discussion at the following link.

Thank you, seems like brass still the option. What about so called titanium alloy nozzle?
