Bronze Filamet™ is the most beginner-friendly metal in The Virtual Foundry range: it prints easily, sinters reliably and gives dense, good-looking metal parts. It prints like PLA on an open-architecture FFF/FDM printer; fired in a kiln it becomes 100% bronze.

Specifications

  • Metal content: 82.0%–86.0% bronze (89/11 tin bronze)
  • Filament density: 4.10–4.50 g/cc
  • Formats: 1.75mm and 2.85mm spools, and pellets (pick in the variant selector)
  • Nozzle: 0.6mm hardened steel, standard flow

Printing

  • Prints similar to PLA with minimal to no warping
  • Feed the filament straight into the extruder
  • Do not dry it: drying degrades the binder (it is less hygroscopic than PLA)
  • Also works in 3D printing pens

Sintering setup

Expect roughly 90–95% density after sintering. A debound (not yet sintered) part has no structural strength, so handle it gently. Sintered bronze can be cleaned of black oxide with Pickling Blend and polished in a Rotary Tumbler.

Applications

  • Gears, art and ornaments
  • Prototypes and functional metal parts
  • Short runs without tooling or machining

Want everything in one box? The Getting Started Bundle pairs Bronze Filamet™ with every sintering consumable.

About this product

Will it print on my printer?
Filamet works on nearly all open-architecture FFF/FDM printers. Swap in a hardened steel nozzle (the size is in the specifications above) and print it like PLA. Not sure about your model? Email us the printer name and we'll check before you buy.
Why start with bronze?
Bronze is The Virtual Foundry's most beginner-friendly metal: it prints easily, sinters reliably and gives dense, good-looking metal parts.
How dense is the sintered part?
Following The Virtual Foundry's debinding and sintering instructions, expect roughly 90-95% density.
Can I debind the part and skip sintering?
A debound part has no structural integrity. Bronze parts can be handled gently if you are careful, but sintering is what makes them solid metal.
How do I clean the black oxide off sintered bronze or copper?
Pickle the part: one teaspoon of Pickling Blend per cup of water, heated to 82C (180F), for 30-60 minutes. Follow with a tumbler and stainless media for a polish.
