Acrylic Bending Machine
Giorgos Lazaridis from PCB Heaven has made a DIY Acrylic Bending Machine. It uses a high power lamp to heat the acrylic from underneath, in about 3 minutes the acrylic is soft and can be bent into any shape you like. The area that the acrylic lays is made out of aluminum and is kept cool with circulated water so that the heating is very focused.
