    One thing you can do with melted HDPE is melt it with hot paraffin wax. Pour it into block molds and you can machine it. When you buy the stuff professionally, it's called machinable wax. It's expensive to buy, so it's worth it to make your own.

    People who use CNC milling machines use it to do test runs. It's great because if an accident happens with the setup, you won't damage your cutting bits as easily.
