  5. 19. An Investigation in Binder Jetting of Copper Graphene Composites

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Rajat Gulabrao Kawalkar; [2022]
    Keywords : inder Jetting; Sintering; Copper Composite; Copper Reference; Density; Graphene;

    Abstract : The purpose of this work is to explore the feasibility of using binder jetting to print copper-graphene composites. This work discusses in detail the approach used to print the composite samples which are optimised through various processes to generate denser parts than a copper reference print and finally discussing various opportunities to enhance development of the process.
