A customer recently gave us a design file and said: “We think PA12 should work. Can you print this? ❓”

After a short conversation and a few key questions, we learned the part would face elevated temperatures and continuous mechanical loads.

While PA12 performs well in standard conditions, those real-world service conditions would likely cause long-term deformation 📉

Instead of printing as-is, we recommended switching to PA12GB to improve stiffness and dimensional stability 🧱

The geometry stayed the same – only the material changed.

That small adjustment significantly reduced the long-term risk of failure.

The customer wasn’t wrong – they simply didn’t have the full application context.

Asking the right questions before printing can be the most critical step in the entire process.

There’s a major difference between just delivering parts and helping customers make better engineering decisions.
