I've worked with acrylics in my previous projects by laser cutting, etching, layering, painting and sticking vynil. Now I want to fold and bend it like a piece of paper. Karl (the college 3D technician)is always on hand to help to intoduce me to new gadgets like the hot wire strip heater and vacuum former. Both of these equipments manipulate acrylics but in different ways.
The hotwire strip heater (below) is this metal machine that is plugged in and the metal thin strip is heated up. The acrylic sheet is placed on top of the heated wire, this is where the acrylic can be bent once heated. It's really easy and is great for angular bends and folds.


For curves the vacuum former is used, this is also a metal machine plugged in, the acrylic is placed on the bed and the lid is closed for about 30 seconds. then the acrylic is turned over onto its other side to be heated and the lid closed again (protective gloves have to be worn for this process). This alternating of the acrylic is done several times and it becomes soft and pliable. At this stage it can be wrapped around a mould to shape it or placed in a die to set it (see below).
