*)Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these ranges if you think it is suitable for your printer. There are a lot of different type of printers, hot-ends and printer offsets that it is extremely difficult to give an overall one-size-fits-all setting.

*) If blobs/lumps form around the nozzle then your print temperature is too high.


Post processing MetalFil - Ancient Bronze/Classic Copper

  • Brushing and/or sand grinding
    • Once printed MetalFil - Ancient Bronze objects can very easily be brushed with a brass brush or sanded with a fine-grid sandpaper. By brushing and/or sand grinding your printed object you will brush/shine up the high concentration of bronze powders.
  • Build-in white polish feature
    • After being brushed and/or sanded MetalFil - Ancient Bronze will reveal its white polish feature.A very thin white layer/haze on your object will now allow you to easily polish your 3D print into a beautiful bronze object.
  • Professional polishing with a rotary tumbler
    • Post-processing a MetalFil - Ancient Bronze 3D printed object with a rotary tumbler will make your FDM 3D printed object indistinguishable from genuine bronze casted objects.
  • Patina post-processing
    • You can create several patina effects on MetalFil - Ancient Bronze printed objects in just one day time. With an ammonia and soda treatment you can for instance easily create a beautiful ancient blue weathering effect on your bronze object.
  • Waxing and coating
    • After every above-mentioned post-processing measure, you can always wax or coat your printed object to get an incredible shine effect.
  • Abrasiveness
    • Please be aware that MetalFil filaments contain a very high concentration of metal powders, which have an abrasive nature.In general, these metal powders will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments.We recommend to use nozzles from stainless steel or other hardened alloys.
  • Nozzle cleaning
    • When printing with filled/composite filaments it is recommended to clean your nozzle immediately after printing by feeding 15-20cm PLA filament through your nozzle.This will make sure that any potential fillers are flown out of your nozzle.It is even better to use glow in the dark PLA as the extremely hard phosphorous particles are much more likely to scrape out residual waste from your nozzle.


Formfutura 1.75mm MetalFil

  • Formfutura MetalFil is a composite PLA filament that is gravimetrically filled with approximately 80% bronze/copper powder. The high bronze/copper content makes 3D printed objects nearly indistinguishable from genuine bronze/copper casted objects. MetalFil can be post-processed with various patina effects.
