.4mm nozzle vs 6 mm nozzle for toys

I recently bought my prusa, and only using for toys. At my surprise some models take over 14 hr to print (mostly articulated);the .4mm nozzle is great with awesome detail but I changed to a steel .6 mm nozzle and all hell broke loose. Horrible prints over oozing from nozzle. I made sure slicer was set for .6mm and prusa slicer settings was set for .6mm detail. Are there different settings for steel 6.mm nozzle that I am missing?? It was so bad went back to .4mm nozzle and sped up printing. Or is .6mm nozzle not good for printing smoothly for toys? And lastly should I have bought brass nozzle instead for better heating/cooling during print

RE: .4mm nozzle vs 6 mm nozzle for toys

I print with all sorts of nozzle sizes all the time and haven't had any issues with 0.6 mm nozzles, brass or tungsten carbide. I for one have had less than ideal experiences with steel but clearly they work for others. But you probably will have to adjust your temperature settings up to compensate for the different thermal profile of steel. Whether a 0.6 mm nozzle will work for you depends on the details on your model. You clearly have less resolution in the xy plane but it's less of an issue in the z direction. I've printed plenty of toys for my granddaughter with a 0.6 mm nozzle.

Ok just a few questions..I bought a steel nozzle, is there a difference in the settings between usingva brass . 6mm nozzle vs a .6mm steel nozzle. Is there a huge difference in the detail between .4mm to .6mm. And besides the settings for the printer to change from .4mm to .6mm and slicing everything for .6mm is there any tips you may have for detail in .6mm?

I print a lot of stuff with 0.6mm nozzles.  Unless I am printing minute details, most prints print without any loss of quality.

What kind of nozzle do you have brass,diamond tip,steel?? And did your setting change?

I almost exclusively use brass.  That being said I have used all but the diamond tip.

Brass conducts heat better and steel wears less with abrasives.

So for detail and heating and cooling aspects brass is the better way to go??

You can't go wrong with E3D for your nozzles. I'd stay away from cheap brass nozzles on Amazon. 

Here's a good Prusa blog post about different nozzle sizes: https://blog.prusa3d.com/everything-about-nozzles-with-a-different-diameter_8344/ if you want tobetter understand the effect of nozzle size on details.

Is there a difference im steel vs brass  

Functionally, the steel nozzle is harder, so it's the better choice for abrasive materials such as glow-in-the-dark filament. But steel also has a different thermal profiles so more likely than not, it will require adjustments in temperature and fan settings for your nozzle. I have had the Nozzle X in the past but found it required to many changes to my print profiles than I was willing to commit to. I now have tungsten carbide nozzles from 3D Maker Engineering and Spool3D on all my printers. Unlike steel, tungsten carbide nozzles work with standard profiles. But as usual in this game, YMMV, I have seen reports of users that seem quite happy with their Nozzle X.

So for detail and heating and cooling aspects brass is the better way to go??

"Better" is in the eye of the beholder. Brass nozzles should work just fine with standard print profiles. Steel may or may not but after running a few test prints, temp towers, etc, with a steel nozzle you should be able to dial in heating and cooling, and if it's your only printer and you keep printing with the steel nozzle, your new custom profiles should serve you well. But in general, I see no advantage of using steel over brass unless you print abrasive materials.

Tungsten carbide nozzles from 3d maker engineering are spendy but completely worth it.  No tweaking. 0.4 for almost any filament, 0.6 for wood. 

Basic PLA to glow in the dark, to carbon fiber or glass or Kevlar infused nylon. My nozzles don’t care, and should outlast my printer. 

Very happy owner. 

Don’t trust forum advice.

Yes, I'm super happy with mine. But they only come in 0.4 and 0.6, plus most of the time they're sold out. That's why I bought 0.8mm nozzles from spool3d.ca.

Just bought a set of tools that come with nozzles..I tried both .6mm nozzles andbneither worked past the first layer test..the filament was underextruding the straight lines looked like more code then input back original .4mm nozzle perfect first layer...what am I doing wrong besides the nozzles are too cheap to use?

RE: .4mm nozzle vs 6 mm nozzle for toys

 Two obvious ideas:

  • Did you redo Live Z ? From your description it sounded like you did but if you see wavy lines that feels like it may not be low enough.
  • Did you slice with a 0.6 mm printer profile? I've certainly done it before--try to print a model sliced for 0.4 with a 0.6 nozzle...

RE: .4mm nozzle vs 6 mm nozzle for toys

did you change the printer profile to one with settings for a 0.6mm nozzle?
and
did you re adjust live Z properly?

Of course, I redid the wizard evertime I changed nozzle and set the printer in HW setup to tje appropriate nozzle size

RE: .4mm nozzle vs 6 mm nozzle for toys

Joan and I meant the Printer Profiles in PrusaSlicer, not the option in the printer's firmware menu, which is largely cosmetic. But assuming you didn't do anything wrong there, it's probably time to ask for some pictures as well as a zipped 3mf project file to come up with additional ideas for what might be going on.

I never got as far as first layer testing...once it could not print a solid straight line...I did not want to take a chance with printing anything..except I did print batman batarang and it came out decent..but not good enough to resell. And once I put original nozzle back..all printing perfect.
