Laser 3D printing used to make ear implants
The research is looking into how to make tiny, 3D printed implants with a memory function or complex shapes, such as the cochlea of the human inner ear.

In cooperation with the Hannover Medical School (MHH), the Laser Zentrum Hannover eV (LZH) scientists are developing implants using laser additive manufacturing (LAM) that change their shape due to temperature changes during the surgery and can thus make the insertion much easier.

The process also allows for the manufacturing of temporary implants, for example magnesium scaffolds that can be slowly and gradually decomposed by the human body. They are also suitable for reconstructing defects of the facial skull, because their shape can be matched to the face of the patient. Directly after the surgery, the bioresorbable implants stabilize the tissue above. Afterwards, they can make room for new bone cells.

The centre will be showcasing the technology at the Hannover Messe which takes place from 7–11 April.
