Actually ferromagnetic – responds to magnets and behaves like iron. Encapsulated in plastic, the iron maintains a stable matte, cast metal finish as printed – can be rusted if desired.  Weighted feel has 1.5x the density of standard PLA. Rustable to create modern artifacts in a few easy steps. Attracts magnets (neodymium type recommended). Prints easily like PLA with less nozzle wear than steel or carbon fiber.

  • Induction at magnetic saturation about 0.15 Tesla.
  • Relative (to air) Permeability – between 5 and independent of frequency up to 1 MHz.
  • Permeability – between 62E-7 and 100E-7 H/m independent of frequency up to 1 MHz.
  • More thermally conductive than standard plastic.

This filament is more abrasive than standard PLA. Be prepared to replace your nozzle and do 1st layer adjustment. Try wear-resistant and/or larger diameter nozzle for increased service intervals.

Usable on most PLA-compatible printers. Processing is comparable to standard PLA. No heated bed required. Process may be less consistent on smaller nozzles and/or Bowden-type machines.  Manufacturer frequently prints using direct-drive systems with 0.4 mm nozzles, though prefers 0.6 mm and 190-210C (standard PLA or a bit cooler) for the best experience.

In filament form, is slightly more brittle than standard PLA, and requires extra care when handling.

 

RUSTING PROCESS (from ProtoPlant Makers of Proto-pasta):

Rust.  Patina.  Artifact.  Great words to describe beautiful weathered finishes you’d expect from old, metal objects, but how is that related to 3D printing?  For a truly unique experience in 3D Printing, Proto-pasta Iron PLA can be rusted to create a modern artifact and here’s how:

What You’ll Need:

  • Safety glasses and gloves
  • A well-ventilated workspace
  • A Proto-pasta Iron 3D Print
  • Rusting solution
    • Hydrogen Peroxide
    • White vinegar
    • Salt
  • Spray bottle, brush, or towel
  • Wire brush (optional)
  • Plastic bag (optional)
  • Some sun or a heating duct (optional)

Steps:

  1. Simply, mix peroxide and vinegar – then add salt until mixture is saturated.
  2. Spray or brush rusting solution on to your Print and watch it rust.
  3. For improved rust effect, try:
    • brushing the surface of your Proto-pasta Iron 3D print to expose more metal,
    • wrapping with a towel and/or sealing in a plastic bag to retain moisture, or
    • warming the solution to accelerate the reaction.
