General printing guidelines *

*) 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 – Brass

Brushing and/or sand grinding

Once printed MetalFil – Brass 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 brass powders.

Build-in white polish feature

After being brushed and/or sanded MetalFil – Brass 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 brass object.

Professional polishing with a rotary tumbler

Post processing a MetalFil – Brass 3D printed object with a rotary tumbler will make your FDM 3D printed object indistinguishable from genuine brass casted objects.

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.

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.

Filament length

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.
