Purpose and goal

The attractive properties of graphene and its availability in a form of powder is of high interest for metal additive manufacturing (AM) technology, for fabrication of high-end industrial products with improved properties. The aim of the project is to demonstrate the processability and properties of graphene-metal -composites manufactured by Filament Deposition Modeling (FDM) technology. In long term, the goal is to manufacture prototypes for high-end industrial applications and verify and validate their properties.

Expected results and effects

The availability of AM technology for manufacturing of metallic components reinforced with graphene will improve the properties and performance of the end-product. In potential applications such as thermal management systems positive effects such increased energy efficiency and improved life time can be attained. The competitivety of the Swedish graphene, metal powder and AM industry will be improved. International leadership on utilizing graphene in new AM products will be gained. The developments contribute to sustainable development in society.

Planned approach and implementation

This activity will establish the process window for the AM technique Fused Deposition Modeling (FDM) and for the proceeding stages curing, sintering and Hot Isostatic Pressing (HIP) for the proposed composites. The focus of the process optimization is on studying on how different parameters within the process chain affect the densification. Advanced characterization techniques are used to measure the thermal and mechanical properties and to identify their correlation to the achieved microstructure.
