FINISHING TECHNIQUES
Whether you want your parts to be polished with the same bright mirror finish of shiny bronze coins or a naturally rustic finish with an acquired patina reminiscent of an aged bronze 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.
Try these techniques separately or combine! Change the order or try something new. If you discover a new technique, make something beautiful, or discover something unexpected, share it! 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.
