Get low cost, strong, lightweight tooling faster with MJF 3D printing

June 24, 2021 3D Printing

We are always looking for innovative ways to solve customer challenges. Recently a customer came to us needing a creative solution for their application. We worked with them to develop a custom automation machine that capitalized on additive manufacturing. In this case, 3D printed tooling helped us produce cost-effective and easy-to-use equipment.

We printed robotic end-of-arm tooling and part nesting components using HP's Multi Jet Fusion (MJF) technology. Here's why...

The customer’s application included several large parts. Each different part had around 20 clips to install in various locations. Installing the clips with robots made sense, due to their flexibility. We created end-of-arm tooling that held several clips at the same time. The robot loaded multiple clips into the EOAT and installed them into the part one at a time. With traditional manufacturing techniques, these tools would have been expensive and slow to make. But with additive, where complexity is free, they were easy and quick to manufacture.

The second challenge of this project was nesting. With a 4-station rotary dial and interchangeable tooling, it was important that tool changes could be done by hand. We considered both machined Delrin and MJF 3D printed PA12 for the tooling. The MJF tooling was 30-60% lighter, 50% lower cost, and 30-50% faster to make. In other words, tool changes were easier, we saved over $20,000, and completed the machine 2 weeks faster. On top of that, we designed more purposeful, unique nesting details that performed better.
