The vacuum former described here will work very well with an inexpensive high vacuum system, getting professional quality results for thick plastic, for under $100. The cost can be under $50 for a high-vacuum system for thick plastic sheets up to about 12' x 18', using a converted bike pump, or an electric air pump of some sort from a thrift store. ![]() For thick plastics (more than about 3/32' or 1/8' thick, depending on several variables) you often need a stronger vacuum than a vacuum cleaner will provide, and again the cost and size of the equipment are roughly proportional to the size of plastic sheet you will be forming. ![]() For larger stuff, you need a custom oven-not very difficult or expensive to make, but a little bigger all around than the plastic it will heat.
