3D knitting takes a digital design and turns it into a piece of clothing. In its simplest form, you download a pattern from the internet and size it digitally to fit the person it is intended for. You then feed the machine with the yarn and let it get on with its job. This is not the first time this type of technology has been developed: in the 1960s and 1970s many knitting machines entered the market from companies such as Toyota, Brother and Singer. What is different this time is that the digital interface is much more sophisticated and 3D scanning, to obtain the individual size and shape of a person, is an established and cheap technology. The time seems right for bespoke clothing, tailored for individuals but made by machines, and UK companies such as Knyttan are already offering this product.
