Shoe designer Katrien Herdewyn wanted 7 different heels printed in 3D. Each of these heels is detachable from the main body and represents one of the 7 deadly sins.

Build around a basic heel shape, each sin is recognisable through different shaped particles on the back, such as tongues, teeth, fans or leaves.

​

The 7 pairs of heels are removable from the shoe, meaning they could be interchanged and attached to other shoes at will.

​

The first thing to tackle in the design process was to model a basic 3D heel that can attach and fit onto other shoes. This base heel was used to make 7 new different pairs.

Using replicators, surface particle generators and prototype sources, a rough layout was made.

With this first visual idea, the particles were frozen into place and were each scaled and placed correctly onto the underlying surface.

​

Once every heel was confirmed to be perfect, getting them print ready was a tedious job.

Every small part needed to be unified and merged together into one big 3D mesh. The amount of detail meant that a lot of stitching had to be done before each heel was ready for printing.
