3D Printing filaments guide
Choosing the right filament
There are several materials that can be 3D printed, each one with different physical proprieties and working temperatures.
The FABtotum can load filament spools up to 210mmx55mm(OD,Thickness), with filament diameter in the range 1.75mm +/- 0.1mm
We strongly suggest using certified official FABtotum brand filaments, as they give more reliable results with our hardware.
You are however free to experiment and use different brands, as long as they use the same material class, diameter and temperature specifications.
See how to load or unload the spools in the load and unload a filament spool article.
PLA (Polylactic Acid)
It’s one of the most used material in 3D printing: it’s a biodegradable polymer that comes from corn.
3D Printing suggested temperature: 200 – 220 °C
Bed temperature: 25 – 65 °C (bed can be at room temperature)
ABS (Acrylonitrile butadiene styrene)
It’s a common plastic polymer, it’s used to print strong parts. Having an higher glass transition temperature could be used to make parts that are used in hotter environments.
3D Printing suggested temperature: 220 – 260 °C
Bed temperature: 60 – 90 °C
One of the stongest material you can find for 3D printing. It can be used for mechanical parts
3D Printing suggested temperature : 245°-255°C
Bed temperature: 90-100°C
Combining PLA or ABS with other additives can be possible and will result in different properties.
Charging the polymers with materials like Carbon fibers, wood dust, metallic powder can make stronger materials or with a nice finishing.
Printing settings depends on the polymer used. Refer to the spool manufacturer or , in case of FABtotum Filaments , the Spool label to get the suggested printing settings.
Flexible filaments can be printed only with the Printing Head Pro
Due to the bowden extruder setup it’s -in fact – usually difficult to print flexible filaments like rubber or TPU with the Hybrid Head or the Printing Head V2.
Doing so will result in filament clogging the extruder and subsequent need to clean it.
