Our woodFill material is available in our webshop and consists of about 70% colorFabb PLA and 30% woodfibre. This means that in general you’ll need to print this material at PLA temperatures. To help you along with fine tuning your machine for woodFill here is our process of calibrating the Ultimaker Original, Ultimaker 2 and Makerbot Replicator 2. Woodfill can be printed with standard 0.4mm Nozzles like a normal filament. If your 3d printer can switch nozzles easily then we definitely recommend trying to print with a bigger nozzle anyways, it is awesome!
For your first prints with woodFill we advise to start out with relatively high layer heights. While experimenting we noticed that woodFill performs better at 0,25-0,3mm layer height, combined with printing speeds of about 50-80 mm/s. These settings ensure that the filament is traveling quite fast through the hot-zone of the extruder so the material can’t degrade within the hot-end because of long exposure to heat. Further down this post you’ll find profiles for the Ultimaker original, Ultimaker 2 and the Makerbot Replicator. You can use these profiles as a starting point and adjust them to your own liking.
A little warning
So about printing woodFill. It’s important to NOT let woodfill stay still in a hot hot-end for too long without extruding.When starting up a new print make sure your g-code and 3d printer are ready to go! Also keep an eye on your printer, if things go wrong then it’s better to shut down the 3d printer sooner than later. This way the woodfill won’t degrade in the hotend and will save you some work cleaning the hot-end.
WoodFill is a bit more free flowing compared to your normal PLA. So a little higher retraction speed and distance might be needed. Using the hollow pyramid we dialled in our settings for the Ultimaker and Makerbot for 0.27mm layerheight profile. To reduce some of the variables we’ll start with the following preset settings:
Minimal layertime: 8s
