Metal Binder Jetting Urea Flange Design

0:00
For our metal binder jetting part, this urea flange was selected because of its potential for lightweighting and net-shape production, which can be leveraged through the metal binder jetting process.

This is an example of a urea flange designed by a customer. We can note the symmetrical outside features.

On the top of the part, we can see a counterbore and three flanges. On the bottom of the part, we have a cone.

On the left, we can see the part DSB designed for metal binder jetting. The outside of the part contains the same symmetrical features, but with considerable lightweighting.

The top of the part has the same counterbore and three flanges, but with lightweighted features. The bottom of the part contains the same cone feature.

Let’s dive deeper into the 3D models of both parts.

As mentioned before, both parts contain the same key features: three mounting flanges, a counterbore on the top of the part, and a cone on the bottom of the part.

With the design freedom of metal binder jetting, the part was lightweighted. As a result, the part has a constant wall thickness throughout, and all unnecessary material was removed from the center of the three flanges.

In addition, the key features can be printed in their net shape. The metal binder jet design could not be produced using conventional manufacturing methods due to the undercuts in the part and hard-to-reach machining areas.
