Tips and tricks
Flexible Filaments
Our 3d printers can in general handle flexible filaments well. Depending on the amount of flexibility, you might
need to take some extra precautions to print it without trouble
.
This is a best practice:
Precautions
.
1.
Ensure you
use the correct slicing profiles
for flexible filaments from our supported software.
2.
Ensure the
extruders are cleared
from non-flexible filaments. It is essential that the filament does not
experience any obstructions in the hot-end barrel, before reaching the hot parts of the hot-end. Otherwise
chances of buckling filament inside the extruder are very high. Obstructions can occur if there has been
printed with some hard filament before, make sure it is removed from the barrel of the hot-end. This can be
done by extruding some hard filament and then fully retract it again. Easy way is to do it via the display unit.
Then slowly extrude the fila flex into the hot-end.
3.
Adjust filament clamping range
. The extruder arm pushes filament onto the extruder drive wheel. When
using flexible filaments it might be that the filament is squashed too much causing a lot of friction and
eventually it buckles and clogs the extrusion.
