    Abstract : Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components.

  7. 5. Inkjet Printing of Graphene-based Microsupercapacitors for Miniaturized Energy Storage Applications

    University dissertation from KTH Royal Institute of Technology

    Author : Szymon Sollami Delekta; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; graphene; supercapacitor; microsupercapacitor; energy storage; printed electronics; printing technologies; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Printing technologies are becoming increasingly popular because they enable the large-scale and low-cost production of functional devices with various designs, functions, mechanical properties and materials. Among these technologies, inkjet printing is promising thanks to its direct (mask-free) patterning, non-contact nature, low material waste, resolution down to 10 µm, and compatibility with a broad range of materials and substrates.
