Extruded Forms

An easy way to adapt a two dimensional shape into a three dimensional form is to ‘extrude it’. This means literally lifting the image vertically from the paper to create a floating shape that can be bridged with a selected material. Of course, this is easier said than done and in sculptural terms it requires some major structural considerations. My grade 9 sculpture class was given such a challenge when they were asked to build an extruded sculpture based upon two combined and unrelated shapes. They began with a scale drawing, which was used to form the two cardboard ends. The gap between the ends was bridged with strips of foam core (a stiff cardboard material). The sides of the sculpture was then wrapped with a thin polished metal sheeting which was beautiful to look at but difficult to use as it had to be cut with tin snips. Hot glue guns that were used to join the initial foam core bridging and the metal. Through patient bending, folding and gluing the metal sheeting was wrapped around the form and carefully cleaned to remove excess glue and finger marks. The ends of the sculpture were then covered with then covered with a colourful plastic material, which also needed to be cut to match the shaped. The final sculpture was then tilted vertically and mounted upon a white baseboard. The final sculptures were very impressive, but it considering the simplicity of the forms they did require quite a number structural skills, so I was particularly proud of their achievements.
