Automated text placement on 3D models: A bachelor's thesis with a future

How an algorithm is expanding Daimler Buses' Digital Warehouse

As part of a joint project between Daimler Buses and SUSI&James, the team tackled an exciting challenge: the automated placement of text on 3D models. Until now, engineers and designers had to manually decide where elements such as a logo, serial number, or licensing information should appear on a component.

This process was time-consuming and subjective. In his bachelor’s thesis, “Generating and Visualizing Suggestions for Text Brandings on 3D Models,” Maximilian Stinner has now developed an algorithmic solution to this problem.

The “Digital Warehouse” is a software solution for Daimler Buses that enables the company to manage its own spare parts and assess their 3D printability. Currently, it is the responsibility of experts to assess the feasibility of printing as well as the placement of markers on the models. The idea behind Stinner’s work: An algorithm is designed to automatically generate suggestions that enable a quick and objective decision.

Stinner’s bachelor’s thesis served as a proof of concept. “The problem had existed for some time, and the thesis provided an opportunity to tackle it in a structured way,” said Dr. Falco Nogatz, his advisor at SUSI&James. Although the solution developed has not yet been put into production, it demonstrates the potential for future implementation.

The prototype developed by Stinner is a browser application that analyzes 3D models, identifies various surfaces, and suggests the optimal placement of text based on specified criteria. Criteria such as visibility, size, and discretion can be defined by the user.

One of the biggest challenges was displaying the 3D models directly in the browser. Since a graphics card could not be used, an efficient solution was needed to render the models clearly. The decision to develop a web-based application was a deliberate one: it was intended to be usable directly without any additional software.

The prototype works well for simple objects such as nuts and bolts. However, the application reaches its limits with more complex and larger files. Nevertheless, the work demonstrates that automated text placement in 3D environments is possible in principle. Even though no comparable product currently exists, the work offers a valuable scientific contribution. It could be of interest not only for 3D printing but also for other applications such as engraving.

The collaboration between Maximilian Stinner and SUSI&James went extremely well. The student, who has since successfully completed his bachelor’s degree and is considering pursuing a master’s degree in media informatics, would like to continue exploring the field of 3D. His work could serve as the foundation for future developments—whether through further student projects or a direct commission from an industry partner.

This innovative approach demonstrates once again how practical research can lead to tangible solutions for industry. An exciting project with great potential for the future!

We would like to thank Maximilian for his contributions and wish him all the best and every success in his future endeavors.

3D printing

Manufacturing companies often face the challenge of having to continue supplying spare parts for discontinued models in the after-sales market. After a few years, these parts are often no longer available in stock, and conventional manufacturing methods result in long lead times. Furthermore, conventional manufacturing is usually only practical for large batch sizes, which, on the one hand, contradicts actual demand and, on the other hand, generates significant costs for repackaging and storing the now surplus spare parts.

Shipping replacement parts to repair shops is also usually expensive and time-consuming. As an alternative, companies can commission local 3D printing service providers to manufacture the parts, thereby providing replacement parts cost-effectively, quickly, and right where they’re needed. However, companies often lack the necessary technical expertise in 3D printing (additive manufacturing) itself. Which parts can be printed using additive manufacturing in a way that meets specifications? How should the print be configured to achieve the best possible result? When does 3D printing make economic sense?

To address this, SUSI&James has developed a solution in collaboration with a manufacturing group experienced in 3D printing: The digital assistant SUSI evaluates parts for their technical feasibility and the economic viability of switching to additive manufacturing. The solution also allows users to request additional services, such as part customization, texturing, or the digitization and conversion of technical drawings into 3D models.

As a result, third-party companies can now benefit from our client’s expertise and network of qualified 3D printing service providers and focus on their core after-sales business.
