Finishing Techniques
- 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.
