Bending steel with plastic 3D printed tools

I’ve been wondering if 3D printed tools could possibly bend steel. It seemed possible unlikely. I designed and printed several tools which are used on a hydraulic press to bend and form steel sheet metal. This particular tool could be made by CNC machining the tools from metal but 3D printing it is much faster and easier. If you’re interested here’s some of the tools that I use in this video: Pneumatic jack conversion for my 20 ton press: Hypertherm powermax 45xp with machine torch:
