Vacuum forming is a fabrication process in which a plastic sheet or film, is heated to high-enough temperatures to give it a pliable texture. It is then stretched onto a mold, using a vacuum, and is cooled into a finished shape.
Plastics which can be used in the vacuum former include HIC (high impact styrene), ABS (acrylonitrile butadine stryrene), and thermoplastic resins such as polystyrene and PVC. The molds can be made of wood, foam, cast aluminum, and acrylic.
The vacuum former can often lead to mixed results and may require a series of tests. Due to the high temperatures and the transformative nature of the material, the vacuum former requires constant supervision and planning.
Due to the high temperatures and the transformative nature of the material, the vacuum former requires constant supervision and planning.
Misuse of the vacuum former will result in a 1 week suspension from booking. After 3 suspensions, you will be barred for the remainder of semester and required to re-take this certification. Examples of vacuum former misuse include:
If you have any concerns with any aspects of this, please talk to Fab Lab Staff or student Lab monitors.
In order to become certified to use the vacuum former, you must schedule an in lab demonstration of the equipment, with the Fab Lab Staff. At the conclusion of the demo, you will be given a code which you can use to complete the short quiz below.
