Post-Processing Instructions from colorFabb [source]:

  1. Sanding: First what you want to do is sand your model with a fairly rough grit of sand paper, something like 220-240 should work nicely. BronzeFill is much easier to sand down then regular PLA, so depending on your model this shouldn’t take too long. By increasing the grit of the sand paper the model will get smoother everytime, exposing the bronze particles at the surface, but it will still look matte and dull.
  2. Steel wool: This tip came in from Paul Braddock, a talented character modelling artist and active member of the Ultimaker community. He used steel wool to polish the surface which will start exposing the bronze particles even more. We’ve tried this method with a fairly fine grade of steel wool and were impressed how shiny it already got!
  3. Shining: Now that the layers are sand down and the bronze particles are already shining a bit on top of the surface it’s ready for the next step. Now this is were it becomes really interesting, since there are so many methods of making bronze shiny. We used a copper polish which gave nice results. It was applied with a dry towel making small circular movements and applying light pressure, then we used another side of the towel to get rit of all the polishing paste.
  4. Bonus: Apart from polishing the material to make it more shiny, one can also apply products to create a patina look.
