  1. 1. Effect of Process Parameters on Contour Properties in Inconel 718 Structures Fabricated by Electron Beam Melting

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Karthik Vaidyalingam Arumugam; [2019]
    Keywords : Process Parameters; Contour Properties; Inconel 718; Electron Beam melting;

    Abstract : Additive Manufacturing (AM), commonly known as 3D printing is a production method that utilises repeated addition of layers in order to produce a final shape. AM utilises less raw material and does not have drawbacks such as tool wear and material wastage as seen in conventional machining. READ MORE

  2. 2. Sustainability of Additive Manufacturing : Electron Beam Melting of IN718

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik; Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Linda Alsing; Sandra Johansson Storm; [2019]
    Keywords : Additive manufacturing; aerospace industry;

    Abstract : The purpose of this thesis is to examine and describe the process of Additive Manufacturing (AM) and the energy use in the production of parts manufactured with the Electron Beam Melting (EBM) technology in particular IN718, which is a Nickel-based superalloy with specification according to UNS n07718 that is used in the aerospace industry. The objectives also include a brief overview of powder bed AM methods and a sustainability analysis. READ MORE

  3. 3. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hamidreza Rastan; [2019]
    Keywords : Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Abstract : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

  4. 4. Effect of Beam Scan Length on Microstructure Characteristics of EBM Manufactured Alloy 718

    University essay from KTH/Materialvetenskap

    Author : Bengt Gustavsson; [2018]
    Keywords : EBM; Electron Beam Melting; Alloy718; AM; Additive Manufacturing;

    Abstract : Additive Manufacturing (AM) as a method is on the rise and allow for a high freedom to create unique shapes without being limited by conventional machining methods. The Electron Beam Melting method, developed by Arcam AB in Mölndal, Sweden, use Powder Bed Fusion together with an electron beam and at an elevated temperature (+1000ºC) to lower stress due to thermal gradients.
