The Spiral Saucepan is a response to a brief asking for an emotive design based on a dining ritual. The act of stirring water to poach an egg was chosen, the physical act playfully replicated through an innovative spiral vessel design.

Developing the form was a challenging process using traditional workshop techniques, not lending themselves particularly well to the spiral shape. Knowing this most of the experimentation was done using 3D printing. 

Using a Printrbot Simple, over 40 sketch models were produced. Each took roughly 15 minutes to print, so the form was able to be painlessly and quickly iterated upon.

Anodized gold aluminium anyone?

Finding a good shape, it was time to print a full-scale model. The final print took over 14 hours:

The print has a really good weight in the hand, and the high quality PLA used was from a supplier in Germany who provide the best PLA with the lowest melting temperatures and highest filament tolerances. Unlike most PLA used for 3D printing which is shiny, it has a chalky matte texture that is a pleasure to work with. It almost feels like wood.

Adding a handle was quite challenging - I borrowed the sweeping lines from classic French saucepans and attempted to join it with the body in a way that didn't compromise the twisting outer surface.

The main body would be made of an anodised cast aluminium for its thermal qualities, weight and appearance - the handle out of stainless steel.

Given the limited scope of the project I didn't have the resources to properly explore tensile strength, heat transfer and material selection, but is something I would love to expand on further.
