FINISHING TECHNIQUES:

Whether you want your prints to be polished with the same bright mirror finish of shiny copper coins or a naturally rustic finish with an acquired patina reminiscent of an aged copper sculpture, the possibilities are endless with this specialty metal PLA filament. With so many finishing options, the sky is the limit! Here are just a few common finishing techniques for metal composite filaments you might want to try:

  • Heat treat your HTPLA print to survive harsher environments like the hot sun or a warm polishing wheel (more details below)

  • Wire Brush to expose metal for future oxidation or a bright, satin finish

  • Rock tumble with steel shot for darker, but smooth, shiny look

  • Paint part (black for example) to fill recesses with a contrasting color

  • Polish with a rotary tool, cotton buff, and polishing compound for a bright, mirror finish on high spots (darkens low spots)

  • Polish with paper for a clean, smooth, and bright finish with less darkening

  • Patina (oxidize) exposed metal naturally or accelerate with a 50/50 vinegar/hydrogen peroxide mixture saturated with salt. Place in sealed plastic bag to retain moisture. Heat further accelerates reaction.



When you've got that perfect, WOW finish, consider preserving it with a clear coat or brush applicable water-based, food-safe, and dishwasher safe coating like Modge Podge.

Now the only question is, "What will you make?"
