The 3D Cocooner buids filigree lattice-structures directly in space just like a caterpillar. It´s nozzle laminates the endless fiber of a e-glass-roving with a liquid uv-light-curing resin to delicate yet highly resistent lightweight-structures.

Unlike most common 3d-printing systems the 3d Cocooner does not work in a 2 1/2 d layer-by-layer construction-logic, but builds it´s 2mm thin fiber-rods supportless in 3d-space.

The spinning-nozzle that is mounted on a vertically set up Festo tripod executes geometry-data, parametrically generated in Cinema 4d.
