MetalFil - Classic Copper is a metal-filled PLA-based filament with approximately 80% of gravimetric copper filling. This incredible high filling with copper powders enables every FDM 3D printer user to 3D print copper objects which are almost indistinguishable from genuine copper casted objects. MetalFil - Classic Copper is easy to print and can be printed on full metal, PEEK, and PFTE hotends and can perfectly be printed with ≥ 0.4mm nozzles with retraction settings enabled on both direct drive extruders, as well as on Bowden style extruders, which is a truly unique feature for a metal-filled filament. MetalFil printed objects can very easily be post-processed allowing one to create amazing copper objects with various patina effects.
80% filled with copper powder
Real copper look and “cold” copper metal feel
Approximately 300% heavier than PLA(density of 3.4 g/cc)
Easy to post-process
MetalFil can be brushed, sanded, polished, waxed, coated and patina post-processed
Very easy to print on both direct drive & Bowden style extruders
Warp-free printing and no deformation after cooling
Improved flowing behaviour and inter-layer adhesion
Good first layer adhesion to several (un)heated print surfaces
General printing guidelines*
Nozzle size: ≥ 0.4mm
Layer height: ≥ 0.1mm
Flow rate: ± 104%
Print temp:± 190 - 220° C*
Retraction: Yes ± 5mm
Heat bed: ± 0 - 60° C
*) 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 - Classic Copper
Brushing and/or sand grinding
Once printed MetalFil - Classic Copper 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 - Classic Copper 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 - Classic Copper 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 - Classic Copper 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. Waxing can be done with products such as beeswax and for coating one can think about products such as XTC-3D.
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.
Filament length ± 92m
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.
