Overview
PLA or PA carrier loaded with real copper powder (30-50% by weight). Prints like a standard filament but produces a genuinely heavy, cold, metallic part. After printing, sand progressively and polish with steel wool or Brasso to reveal a real copper surface that oxidises naturally over time. Stunning results with the right post-processing.
