Abrasive Exotics are not for Everyone

Some of our filaments include materials which, even when finely ground, will increase the wear on your printer nozzle if your nozzle is made of a “soft” metal, like brass. After printing as little as 500 g of filament, there can be measurable increase in the diameter of a brass nozzle.  Ideally your nozzle is made or coated with a hard material.  In either case, you should be both financially and technically prepared to replace your nozzle (have at least one extra on hand).

The following Proto-pasta filaments are noticeably abrasive (ordered most to least abrasive):

  • Stainless Steel PLA
  • Magnetic Iron PLA
  • Carbon Fiber PLA

Replacement nozzles cost less than $5 and as much as $25. " Hopefully, replacing a nozzle is worth the ability to print with metal and other advanced materials on your affordable 3D Printer.  In the meantime, we are investing in solutions to minimize the cost, complexity, and downtime associated with frequent nozzle replacement. " Some machines are not easily serviceable so please make sure yours is.  For this reason, abrasive exotics are not for everybody (but pretty amazing for the adventuresome).

Magnetic Iron Printer Settings

Proto-pasta Magnetic Iron PLA prints at similar temperatures as standard PLA, though we have found it seems to like it about 10 degrees cooler than what we usually print PLA at. Quick cooling seems to increase the tendency to warp, so you might try turning your fan off and slowing your printer down a bit. Experiment and see what work best with your machine.

Bed Temp (if available, is not required): 50° C
Hot End Temp: 190– 210° C

Carbon Fiber Printer Settings
Because of the chopped carbon, Proto-pasta Carbon Fiber PLA may have trouble getting through smaller nozzles. We have had good success using a .5mm nozzle and direct-drive spring loaded pinch-roll style extrusion head.

Generally, our customers find it prints just like standard PLA on their machines (at around 195-210° F), though others find success running it a bit hotter (around 220° F). Experiment with your printer and see what works best for you.
