Step 25: Platen: Overview
The plastics in this part are something you should buy new. Unfortunately, I have found no good way to make a platen from recycled materials. I have made 4 platens in total, and the first two used recycled scrap plastics (there is a surplus shop in town that sells acrylic cutoffs and scrap). The first platen could not be glued because the plastics were slightly warped, and the second one, the paper covering that protects the acrylic had become hardened and almost impossible to remove. A tip: near-boiling water will remove such paper, but it is not fun.
Save yourself the pain and go buy new, clean plastic. You won't regret it.
2 11x15" cuts of 1/8" clear acrylic.
2 6x6" squares of 1/4" clear acrylic.
Some methylene chloride.
A syringe or applicator.
A tongue hinge.
A chunk of scrap wood (or two).
