Digi-fabric consists of tiny geometric shapes—squares, hexagons and the like—which, when linked together in a printed fabric swatch, allow multi-directional stretchiness. Just like this collapsible lamp shade or this jointed necklace, the digi-fabric doesn’t have to be assembled or woven–rather, it can be printed in one fell swoop.
The process works by sweeping a laser across a pan of powdered nylon; when the lasers hit the nylon, it fuses (“sinters”). The process repeats in layers, until the final product emerges. Thus, you can create interlocking shapes all at once–for example, a chain whose links are completely closed.
