Starting with the basic idea of using a hot glue gun to form and build up a model, why not make whole objects in this way? Why not shoes? If you attach that glue gun to a robotic arm and the glue into a light filament – voila: LightSpray.

LightSpray is a technique that use a robot arm to spray a recyclable filament around a mold to create a seamless one-piece upper that is directly attached to the midsole, eliminating the need for stitching or glue. The entire shoe is fully assembled in just 3 minutes. Supposedly coming Fall/Winter 2024.

The video is pretentious – thinking they invented something new – but it does get the idea across. Like Nike’s attempts at 3D printing, and 3D printed clothing, I think it’s definitely going to change things.
