PPP Slowenien – Additive Manufacturing using biobased materials

The overall goal of the project "Additive Manufacturing using biobased materials" of TU Bergakademie Freiberg and the University of Ljubljana is the utilization of renewable and biocompatible resources for additive manufacturing technologies under the consideration of specific process requirements of the most established AM processes: FDM (fused deposition modelling) and 3DP (3D-printing).

The usage of biogenic remnants in additive manufacturing is very little addressed so far. The primary focus will be on the adaptation of the (biobased) material mixture (material science), process control (production engineering) and evaluation/control of the product characteristics in order to ensure a long-term industrial usage of the manufactured components. The technology readiness level (TRL) of the material/process combination shall be increased from TLR2 to TLR4 and verified by selecting and producing a suitable demonstrator.

By combining the knowledge of both partners, renewable materials for 3D-printing can be applied in different processes. TU Bergakademie Freiberg focuses on powder materials for inkjet-binder-based 3DP, while the University of Ljubljana addresses filament-based materials for FDM. All materials will be assessed for their printability, but also their mechanical properties after printing. Furthermore, the geometric accuracy and achievable tolerances will be measured. Here, complementary laboratory equipment of TU Bergakademie Freiberg and the University of Ljubljana will be used to maximize the information gained. The project will integrate young scientists, PhD students and established researchers and foster an active exchange, multiplying the impact of the scientific results.

The project is funded within the scope of the PPP programme of the German Academic Exchange Service (DAAD).
