3D-printed bearing rings

0

Franke lightweight bearings with housing parts from the 3D printer are probably the lightest bearings in the world. Made from the finest aluminum granules and equipped with a lightweight yet solid honeycomb structure, they are up to 90% lighter than conventional steel bearings.

How das 3D-printing work?

First, the components are created in a CAD program. The program breaks up the component into countless layers to send the laser tothe right track level by level.

 

The aluminum powder is solidified in the printer at the points which later form the housing parts by means of a laser beam. After each laser layer, new powder is applied and laser-etched again. This is done as long as the whole part is „printed“.

To make use of all the space available, several parts are printed simultaneously. In our case, four complete bearings could be manufactured in one go. The printing is done within 13 hours.
