Making a 3D Printed Exhaust Duct Connector for a Stratasys 3D Printer

3D Printed Duct Prevents a Smelly Lab

3D Printing

Many of the 3D printed projects that we do from our GoEngineer office in California use materials that are essentially odorless. But there are some materials, such as Ultem, which produce smelly fumes. Since nobody wants to be the one who smells up the lab, I worked with Josh Zuniga, additive division technical manager at GoEngineer, to make a customized duct connector to provide exhaust capabilities for one of our Stratasys 3D printers.

First Steps

As a first step, I used my calipers to get some measurements off the machine just to make sure I modeled a part that didn’t interfere with the machine itself. The duct adapter’s design would need to fit a rectangular opening from the 3D printer and then into a ten inch flexible round duct in the ceiling. (I spent about 30-minutes modeling it in SOLIDWORKS.)

Flanges for Adhesion

I modeled flanges off the sides of the adapter to allow room for double-sided adhesive so we could securely stick it to the printer. I also modeled up a little rubber gasket to make a tight fit all-around.

One of the design requirements was to be able to print the part as a single piece. So we had to dimension it exactly for the machine (Stratasys F370).

Fast, Easy—and it Works!

All-in-all, it was a quick job from beginning to end. And now we have a customized duct adapter that allows us to keep our lab smelling as clean as it looks.

Thanks to the Utah additive manufacturing team for helping with this cool little project!
