  1. 16. Application and Evaluation of Current Guidelines for Metal Additive Manufacturing

    University essay from Lunds universitet/Innovation

    Author : Robin Bergman; [2022]
    Keywords : additive manufacturing; laser powder bed fusion; thin-wall structures; design for additive manufacturing; design guidelines; Technology and Engineering;

    Abstract : The goal of this thesis has been to evaluate the design guidelines that currently exist regarding designing for metal additive manufacturing (AM). More specifically, this project has focused on the design guidelines regarding thin-walled features and how well they work when applied to adapt an industrial part for manufacturing with the AM process laser powder bed fusion (L-PBF).

  6. 20. Improvement and Development of Powder Spreadability Testing

    University essay from KTH/Materialvetenskap

    Author : Fabrice Rosala; [2021]
    Keywords : ;

    Abstract : With rising interest in metal additive manufacturing and, specifically, in powder bed fusion processes, it is essential to understand relevant process parameters and the behavior of powders used in such processes. At the time of writing, the flow behavior of powders is in the spotlight whereas little research into the spreadability of a powder is being conducted. READ MORE
