Cast Origami_

Boundary Pushing Model Plaster Skin The idea behind this method of thinking is to push the physical boundaries of the material plaster and question the limit of which applies to the material form. Plaster is a material that takes any form its given provided its cast in or around a mould. my aim is to directly question this idea of casting in thinking of other ways plaster can be used to its physical limits. Casting origami surface forms is something that has interested me for a while and is an ideal application for a material like plaster. However, I won’t be casting from a moulded volume but from the surface of the form itself. I do this by effectively painting a thin layer of plaster all over the folded form. The layers are built up until thick enough for the mould to be pealed away without snapping. Then I have a thin rigid version of the folded form.

The origami form was first folded out of a sheet of acrylic. I feared that folded paper would absorb too much water out of the plaster and would deform the surface. The plaster painted surface is roughly 1mm thick but this varies across the form

The cast surface lends possibilities to create an interior volume. Perhaps concrete could be used on a much more grand scale to achieve the same effect as above. On a smaller scale as modelled, there is definitely scope for items of product design such as lamp shades or bowls.

Cast Origami_ The Light and Heavy Origami Tiles The idea behind this method of thinking is to investigate how the feeling of mass and weight can be juxtoposed against lightness in the form of a cast surface. Unlike the previous plaster exercise this will be more of a straight forward cast but for this one the craft of the mould is of utmost importance. I have produced an original tesselating pattern based on hexagons and triangles and when teased into shape provides a very intersting and satisfying interlocking surface. After developing the pattern I printed the ‘mountain and valley map’ onto a piece of acetate sheet. The lines were then scored with a scalpel and folded by hand.
