  1. 1. A Business Model Perspective on Additive Manufacturing

    University essay from KTH/Industriell Management; KTH/Industriell Management

    Author : INGRID PORAT; KLARA HOVSTADIUS; [2018]
    Keywords : additive manufacturing; business models; Gartner’s hype cycle; additiv tillverkning; affärsmodeller; Gartner’s hype cycle;

    Abstract : Additive manufacturing (AM) is an immature manufacturing technology which is often considered to have the potential of disrupting the manufacturing industry and many industrial companies are currently investigating how they can position themselves within the AM market. Technological innovations alone are often insufficient to fully exploit the benefits of new technology and requires to be accompanied with business model innovation. READ MORE

  3. 2. 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.

  4. 3. Alloy 718 manufactured by AM Selective Laser Melting : Evaluation of microstructure and weldability

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Valeri Ivanov Petkov; [2018]
    Keywords : Inconel 718; Selective Laser Melting; Additive Manufacturing; Heat Treatment; Weldability;

    Abstract : Inconel 718 is one of the main superalloys that are used in hot structures of jet engines today, because of its excellent mechanical properties at high temperatures and its good weldability. This material has been extensively used and studied in cast and wrought forms during the past decades. READ MORE

  5. 4. Residual stresses and distortions in austenitic stainless steel 316L specimens manufactured by Selective Laser Melting

    University essay from Högskolan Väst/Avdelningen för svetsteknologi (SV)

    Author : Henrik Nöbauer; [2018]
    Keywords : Residual Stresses; Distortions; SLM; Selective Laser Melting; 316L; X-ray diffraction; XRD; ESPI; Hole drilling;

    Abstract : Residual stresses are one of the major challenges in additive manufacturing of metallic materials today. They are induced during manufacturing because of the rapid local heating and cooling and may cause distortions, cracking and delamination between layers. READ MORE

  6. 5. QUALITY IMPROVEMENT OF CERAMIC PARTS FORMEDICAL APPLICATIONS THROUGHOPTIMIZATION OF THE ADDITIVE MANUFACTURING ANDPOST-PROCESSING PROCESSES

    University essay from KTH/Industriell produktion

    Author : Eva Hofacker; [2018]
    Keywords : ;

    Abstract : Additive Manufacturing (AM) is beneficial for medical applications in which tissues must be replaced because AM enables the fabrication of highly complex three-dimensional structures. In this study the AM and the post-processing steps of additive manufactured ceramic parts of a specific material for tissue replacement were examined in order to optimize the parts’ quality. READ MORE
