A Robotic Arm That Is Capable of 3D Printing Wool

What if you could 3D print wool? The range of materials compatible with 3D technologies conitnue to surprise us, with everything from coffee to beer available! Now, in a project led by a Dutch designer, Christien Meindertsma, a tailor-made robotic arm has been made that is capable of depositing wool layer by layer and forming all kinds of objects, without adding water or any other material. Called FLOCKS Wobot, this robot gives a second life to wool that cannot be used in the textile industry because it is too fine and would therefore be thrown away.

The designer’s project is part of contributing to a circular economy. Her website states that 1.5 million kilos of wool (or about 3.3 million lbs) are thrown away every year in the Netherlands. Meanwhile, in the US, in 2022 alone, 11.9 million lbs were, so imagine the ecological consequences if all that ends up in waste. Her solution aims to fix that.

3D-printed wool offers many advantages

What’s more, wool has a number of advantages over other materials such as polystyrene: it’s recyclable and biodegradable, strong and solid, has excellent insulating properties and is permeable to water. It is also fire-resistant (up to 560°C). Wool could therefore be a good material of choice when combined with 3D printing.
