By combining the two technologies, the project aims to develop a test system that not only enables the investigation of direct effects of airborne nanomaterials on human respiratory models, but also the investigation of effects on other organs. In addition, the test system is to be tested as an example for assessing the hazard potential of (nano-)materials produced in additive manufacturing processes such as 3D printing.
