Precision Board Plus
High density urethane foam that is ideal for milling
Precision Board Plus High Density Urethane (also known as tooling board, a competitor to RenShape or Ren board) is a closed cell rigid urethane foam board that can withstand up to 200º F continuous exposure. It can be cut or bonded into a variety of shapes for final machining or shaping. Higher machine feed rates are easily achieved compared to wood, epoxy and alloy substrates. The material mills beautifully and is safe to laser cut/laser engrave. It has a density of 48 lbs per cubic foot. Buy everything you need to glue the material, repair nicks or holes, and prime for your final finish.
This project is no stranger to these feelings I have and can teach a lot of things to anyone attempting it. We gave it a try at our hackerspace H3 Laboratories
There are various ways that you can do this project of course, so you can take ideas and go melt some aluminum at your house or hackerspace. Invite some people over and melt Aluminum together. It may look simple but it is very enjoyable and camaraderie forming.
