  1. 1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Johannes Lövhall; [2024]
    Keywords : Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

    Abstract : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.

  3. 2. Differens i volym mellan skördardata och laserdata i slutavverkningsbestånd

    University essay from SLU/School for Forest Management

    Author : Sarah Olofsson; Felix Östlund; [2023]
    Keywords : flygburen laserskanning; fjärranalys; slutavverkningsbestånd; skördare;

    Abstract : Sedan den flygburna nationella laserskanningen påbörjades 2009 har Skogliga grunddata blivit ett viktigt verktyg för de verksamma i skogsbranschen både tidsmässigt, praktiskt och ekonomiskt. Lantmäteriet, Skogsstyrelsen och Sveriges lantbruksuniversitet påbörjade 2018 en andra nationell skanningsomgång. READ MORE

  4. 3. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    University essay from Uppsala universitet/FREIA

    Author : Karl-Fredrik Boholm Kylesten; [2023]
    Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

  5. 4. 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
