Julia Koerner / JK3D / Setae Jacket

The design explores digital setae pattern and multi-colour 3D printing on fabric, inspired by microscopic butterfly wing patterns. Butterfly wings are made up of membranes which are covered by thousands of colourful scales and hairs, plate-like setae. Photographs of the Madagascan Sunset Butterfly wing setae are digitized into an algorithm which translates the colour pixels into 3D bristle patterns which correspond to the form of the garment design.

Materials and techniques:
The digital designs are 3D printed with an innovative technology, without any support material and directly on fabric. The relation between the colourful rigid setae and the flexible fabric create enigmatic visual effects when the garment is in motion. The design has been featured the exhibition was called: “Designs for Different Futures” at the Philadelphia Museum of Art and Walker Art Center in the US. 2019-2021.
