The heating bed will be made of four copper clad boards. A design will be made on a computer and printed onto a piece of glossy paper. The paper will then be ironed onto the copper board so that the design sticks. We will then use a ferric chloride solution to remove all unwanted copper. This allows us much more freedom then we would have if we purchased a prefabricated board. This also allows us the freedom of designing a board that is capable of being turned on in sections.
