Important results from the project
Within the project, an electrically conductive composite material based on Nylon and graphene was developed for Additive Manufacturing (AM) using the "Selective Laser Sintering" SLS" method. The material can be used to manufacture objects with AM which is ElectroMagnetic Compatible (EMC). For example, enclosures that make the contents not disturbed by radio emissions but also to make conductive objects that do not charge up and release an electrostatic discharge ESD.
Expected long term effects
We have developed a new composite material that is used in AM machines to manufacture electrically conductive objects. Together with the partner 2d fab, we have developed a method to functionalize graphene, which enabled the manufacture of the polyamide/graphene composite material. The developed material is a possible new product for 2d fab which would then be a subcontractor to the AM industry. The material we developed is in many respects good enough, but some development is needed.
Approach and implementation
We have worked with 2d fab when it comes to developing the composite material, especially when it comes to functionalizing graphene. With Lasernova we have worked with evaluation of laser sintering of the developed composite material. Above all, the high-speed camera has contributed to an increased understanding of melt and the flow processes. Wematter has used the developed material and carried out successful test prints in its own developed AM machine.
