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 softwares.
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 filaflex
into the hot-end.
3. Adjust filament clamping range. The extruder arm pushes filament onto the extruder drivewheel. 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.

Loading filament.
It is recommended to load filament via the interface at the printer. Goto Control => Change filament => Choose the
correct filament and/or temperature.
1. Cut the end of the filament in a skew manner. The extruder gears might find it difficult to get grip onto the first
part of the flexible filament which is fed into the extruder.
2. Extrude filament until the first drip comes out. Then slowly extrude more piece by piece. Do not extrude in a
continuous feed at high speed as that will increase chances of buckling.
3. Optional: Lower the overall print speed. Via the display unit take the following steps after starting the print. Press
the rotary button. Then scroll down to Speed Mul. And lower it to 50%. Then by trial and error increase the speed.
