Improved Rusting Method for Iron Prints

Posted by ProtoPlant Makers of Proto-pasta on

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 your part with a towel and/or sealing in a plastic bag to retain moisture
    • warming the solution to accelerate the reaction
Here is Dustin demonstrating how easy it is to rust your Proto-pasta Iron prints!
