WoolyFil arrives on the market as the first commercial filament using a dye derived from wool instead of synthetics or fossil fuels. Made from recycled PLA, this material offers 92-98% biogenic carbon in its pigments. Available in Green Marble and Riverstone, in 500 g and 1 kg spools, it promises a cleaner footprint without losing functionality.
The science behind the wool dye 🧪
Wool Source's patented technology transforms strong wool fibers into fine color particles that integrate with other materials. The filament prints with a 0.4 mm nozzle at 180-200 °C and a heated bed at 50-60 °C, standard parameters for PLA. This makes it easy to use in conventional printers, maintaining mechanical properties similar to those of standard PLA but with a more sustainable origin.
Programmer sheep: the new filament profile 🐑
Now it turns out that sheep not only provide wool for sweaters, but also for 3D printing dyes. If your part comes out with an uneven tone, don't blame the slicer: maybe the sheep in question was having a bad day. At least, when your project warps, you can console yourself thinking it's an animal's fault, not your lack of calibration.
