DIY Incremental forming machine

I would like to introduce Incremental forming. This is one of old numerical control machining method. Recently,desktop fabrication machine can be seen in large fabrication research in the world.But most of their research is conducted with 6-axis robotic arm. Not only It's cost high.
By using this, A thermoplastic sheet is deformed by 3D data. I introduce architectural application Japanese traditional work shouji by specific paper.
