3D printing: The future, layer by layer
04.11.2025
How does a 3D printer work? What innovative technologies are available? And where are they used? Dr Dorothea Helmer, head of HelmerLab with projects at the Freiburg Materials Research Centre, gave over 70 school pupils an insight into the fascinating world of 3D printing at the Freiburg Seminar.
3D Printing in Focus
Watching certain things is particularly enjoyable. A 3D print is a prime example: layer by layer, an object grows until it’s complete. Dr. Dorothea Helmer explained the process behind this during her lecture at the Freiburg Seminar.
Besides the function and materials of 3D printing, the students learned about innovative printing technologies – such as volumetric 3D printing, which prints simultaneously in all directions, and Embedded Printing, where objects are directly integrated into other materials.
But it wasn’t just about technology: The lecture also showed how research actually works, what scientists do all day, and why their work is so important for our future. Afterward, the participants had the opportunity to ask questions; there was lively discussion, joint thinking, and further development
