Maximum quantity available reached.

Brick or cast brass? Brush, polish, or patina and enjoy!

Introducing Brass-Filled Metal Composite HTPLA. A professional-grade, heat treatable PLA filament which maintains strength and form at much higher temperatures than PLA, ABS or polyesters like PET.

Using real brass powder, we've created a premium heat treatable metal PLA filament for 3D prints that finish just like real metal! Our brass composite filament is as versatile as it is beautiful, printing like plastic, but finishing like real metal for beautiful, durable parts from most standard 3D printers.

Whether you want your prints to be polished with the same bright mirror finish of shiny brass coins or a naturally rustic finish with an acquired patina reminiscent of an aged brass sculpture, the possibilities are endless with this specialty metal PLA filament. With so many finishing options, the sky is the limit! 

  • 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.
Heat treating beforehand to firm up HTPLA helps parts hold shape up to near melting (175C). Protect your investment in warm environments or push limits of application by exploring copper's thermal conductivity.  There is not enough copper to be electrically conductive, sintered, or plated, but there is a noticeable difference in weight and heat transfer. Some application ideas include:
  • Faux brick or sand
  • Fixtures or hardware
  • Knobs or buttons
  • Heat sinks or exchangers
  • Fine art & sculpture
  • Emblems, signage, or trophies
  • Jewelry, like pendants or bracelets
  • Cosplay, game pieces, or figurines
Material data:
  • Base resin: HTPLA - Heat Treatable PLA
  • Additive: Real Brass Powder
  • Particle size: less than 250 micron (0.25mm)
  • Odor: low or no
  • Density: Approx. 2.30 g/cc
  • Length (500g): 97m (1.75mm) and 36m (2.85mm)
  • Heat treating: 110C (225F) for 10 min or as required for desired result
  • Total loss of stiffness (before heat treat): 50-60C (Tg)
  • Total loss of stiffness (after heat treat): 150-175C (melting)
  • Dimension change (before heat treat): 0% X/Y/Z
  • Dimension change (after heat treat): 1.5% shrink X/Y and 1% growth Z typical but please calculate and confirm for your specific print and process
Printer settings:
  • Speed: 10-20 mm/s 1st layer, 20-80 mm/s rest of part
  • Nozzle Set-point: 185-215C (hottest on 1st layer for best adhesion)
  • Nozzle Actual: maintain set-point, reduce speed if less than 
  • Nozzle Type: Standard or wear resistant for extended use
  • Nozzle Diameter: 0.6mm or larger preferred, 0.4mm okay with 0.25mm minimum for experts
  • Layer thickness: 0.15-0.20mm recommended for a balance of quality, reliability, and productivity
  • Bed Temperature: Room-60C (over 60C can worsen warp)
  • Bed Preparation: Elmers purple disappearing glue stick or your other favorite PLA surface preparation
This material has been flow optimized and has less moisture uptake than standard PLAs, however composites are still sometimes more tricky to print depending on hardware and software settings.  The main challenge is to keep mass flow up (larger nozzle + fast speed) and in a single direction (minimal retraction) to avoid heat soak.  More on that topic here.
