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.
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.
