We’ve been working on development tooling for pulp paper forming!
For this process, a pulp water solution is used to pull through the tool to form the part.
The tool is a stainless steel 3D printed metal tool with 9,000 honeycomb cells. The 9,000 holes in the tool are used so that when you are pulling the part, it pulls the water through to form the part.
This is just another unique way that we use 3d printed metal tooling. We have also be used this for standard thermoforming, which can provide a long tool life.
