3D printed bearing design and manufacture
The German manufacturer Franke GmbH designs and manufactures wire cage rolling bearings as a lighter alternative to traditional rolling bearing designs ( fig.
1 ). The history of this product began in 1936, when engineer Erich Franke, while developing an optical device, was looking for a solution to save space and invented a special rolling bearing. A feature of bearings of this type was its non-standard design: instead of ordinary and outer rings, 4 round guides were used ( fig. 2). They formed the basis of the products manufactured by Franke GmbH and are today used in many industries such as
aerospace and medical equipment, as well as for the automation of various processes. Despite the fact that bearings of this design have been thoroughly researched, the specialists of Franke GmbH decided to apply innovative approaches and methods in their design - in particular, topological optimization. This allowed to reduce the weight of the structure.

It is worth noting that Franke GmbH has been using 3D printed aluminum housings for several years now. The applied additive manufacturing methods allow saving material without losing the strength characteristics of the product.
Wire cage bearings are used in the installation of satellite antennas and are needed for organizing telephone and Internet communications in aircraft ( fig. 1 ). These types of antennas are often located in the rear fuselage and must be turned on during flight, staying in line with the satellites to ensure unhindered data transmission. At the same time, the swivel mechanism itself should be as light as possible.
3D printing and modeling
In order to understand the economic impact that can be achieved with modern technologies such as topological optimization and additive manufacturing, Franke GmbH has attracted two partners - Rosswag Engineering, an additive manufacturing integration and 3D printing company, and CADFEM GmbH specializing in numerical simulation.
The original bearing provided by Franke GmbH was 25 cm in diameter and contained outer and inner rings. They consisted of two parts, which were made of aluminum, maximally optimized for weight and prepared for CNC machining.
CADFEM GmbH imported the geometry provided by Franke GmbH into a single integrated system for Ansys Workbench analysis project to use it for preliminary modeling. It allows you to determine how the original bearing works when operating in various modes. The obtained data provided the criteria ( fig. 3 ), which experts were later compared to when comparing the original design with the optimized one. After determining all loads and sections without change, topological optimization was started. The Ansys Mechanical solution made it possible to determine insignificant stresses over the entire area of the cage, and the topological optimization tool proposed to completely remove the material in this area ( fig.
4, 5).

4. Red areas show which material to keep, blue areas to remove
fig. 5. Stage of topological optimization. Remaining material is shown in gray
Fig. 6. Filling the “empty” space with a lattice structure
After that, it was decided to fill the empty space with a lattice structure. Such structures bring additional advantages with very low weight and maintaining the rigidity of the model ( fig. 6 ). The lattice had minimal dimensions, which made it possible to produce it using 3D printing.
16% weight reduction
Initially, the bearing housing was made in the traditional way and sufficiently optimized. Topological optimization reduced its weight by another 16% using additive manufacturing.
But the simulation itself does not end there.
The second important area of application of numerical simulation is the printing process itself ( fig. 7, 8 ). Metal printing uses a significant amount of energy to completely melt the metal powder particles. At the same time, the cooling rate is also quite high. These temperature gradients create strong stresses in the workpiece itself. Supports are required to ensure thermal conductivity during the manufacturing process and to absorb the resulting forces and stresses. Their creation, in turn, increases the printing time and makes subsequent machining a necessary step.

8. Simulation of the printing process. Milestones
“We worked on this model with parameters that match exactly the selected material. We've already done calibration tests on projects we've previously done with Rosswag Engineering.
Thanks to this data on material properties, we were able to optimize the shape and type of supports, while also taking into account such print parameters as movement speed, laser power and component orientation in space,” comment CADFEM GmbH.
“For the print simulation, the specialists worked closely with Rosswag Engineer-ring,” says Franz Öhlert, designer at Franke GmbH. Each of us shared our experience. We have added additional points for post-processing. Material is specifically added to the product at points where post-processing is needed, such as at the location for installing a bearing. We also determined the location of the supports. The whole model was then brought back into CADFEM to simulate the printing process."
In the final step in Ansys Additive Prep, a custom print solution, the engineers created layout files for the SLM Solutions printer that produced all the parts ( fig. 9 ). The finished printed bearing housing was delivered to Franke GmbH for further processing, assembly and assembly with wire rings, rolling elements and a cage.

Franke GmbH says: “It was a pilot project. We wanted to know how much savings can be achieved through topological optimization and 3D printing. But it was a very interesting collaboration. We have shown that we can control the printing process with Ansys Additive software. Modeling and optimization are so realistic that the process itself runs smoothly. And the 16% weight reduction of an already optimized component also confirms that topological optimization and 3D printing are taking their rightful place in manufacturing.0003
