Limited experiences with nozzles and wear

After printing hundreds of kilograms of filament through several printers and consequently destroying dozens on nozzles along the way; I have probably learned nothing, but let's take a look anyway!

Cheap brass nozzles from Aliexpress, Ebay, Amazon, etc.
  • These can be found in a 10 pack for around $20 USD
    • At least 5 are completely usable out of the box
    • Usually a couple more can be made functional with some cleanup and deburring
    • Never had a complete batch that were all usable out of the box (No threads on one)
  • For this price, it is an acceptable choice for those willing to tinker, replace nozzles more often, and get less overall quality
    • Had more than one break out the nozzle tip after some long PLA prints
  • Occasionally seen warping or crumbling after torching out a clog
  • These WILL work in a pinch, so I used to keep a handful for emergencies

E3D brass v.6 nozzles
  • These seem reasonably priced to me at around $5 USD so I now keep a handful of these around instead
  • When I want a brass nozzle for highest print quality, this one has great tolerances and longevity (for brass)
  • Tolerates being torched out after a clog now and then without issues

E3D Hardened Steel and Nozzle X coated v.6 nozzles
  • These are quite affordable for Wear Resistant nozzles at around $20 to $30 USD
  • Raise all nozzle temperatures 5-10 C to accommodate it's low thermal conductivity compared to brass
  • Wear resistant nozzles are REQUIRED to print abrasive materials such as composites (Carbon/Glass Fiber, Glow-In-The-Dark, Sparkles, Wood, Stone, etc.)

Everything else I haven't tried yet

Any opinions I have on other nozzles must be purely based upon the evil marketing strategies of 3D printer nozzle manufacturers

  • Low thermal conductivity makes sense (to me) as a real limitation to quality etc. in wear resistant nozzles but inertia is also a strong motivator
    • Makers of the DiamondBack nozzle claim it has a thermal conductivity comparable to brass
      • Maybe I'll just "loose" the crusty old nozzles then I can get the new hotness!
