The Reinforcements
What's metal filament?
PLA or PETG packed with metal powder: heavy, and it can be polished to look like real metal.
- Gainsweight and a metal look
- Notmetal strength
- Needsa hardened nozzle
Base plasticusually PLA or PETGMixed inmetal powder (copper, bronze, steel, tungsten…)
Nozzle 190–270 °C · Bed 60–100 °C
Prusa, for wood- and metal-filled filaments (depends on the base). Typical ranges from one maker’s data sheet. Brands differ: the label on your spool wins.
Why it matters
- Sand it wet (600 to 1500 grit or finer), then polish: it shines like metal.
- It looks like metal but is weaker than the plain plastic.
Tips from the workshop
- Metal-filled filament is highly abrasive: hardened steel nozzle only.
