  1. 1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

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

    Author : Kaibin Wen; [2023]
    Keywords : Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

  3. 2. Increased build rate by laser powder bed fusion of SSAB steel powder

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Colin Daly; [2023]
    Keywords : Additive manufacturing; Laser powder bed fusion; Build rate; Steel powder;

    Abstract : SSAB has built a pilot gas atomization facility looking to expand their expertise of steel into the metal powder and additive manufacturing industry. Laser powder bed fusion is an additive manufacturing method that melts and fuse metal feedstock powder together layer by layer using a high intensity laser. READ MORE

  4. 3. Process characterisation of an additive manufacturing equipment : An analysis of the effect of electron beam powder bed fusion process parameters on the melt pool geometry and microstructure of Ti-6Al-4V

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Ida Ljusell; [2023]
    Keywords : Additive manufacturing; AM; 3d printing; titanium; process characterisation; electron beam powder bed fusion;

    Abstract : Additive manufacturing (AM) are manufacturing methods where components are produced by adding material layer by layer which allows for a high freedom of design as well as little or no material waste compared to conventional manufacturing methods. Despite the many benefits of AM there are still problems concerning the quality of the produced material. READ MORE

  5. 4. Melt pool Geometry and Microstructure Characterization in Additively Manufactured WE43 Alloy
