  1. 6. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : David Aronsson Edström; Oskar Lundberg; [2022]
    Keywords : 3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Abstract : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. READ MORE

  3. 7. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Måns Boll; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  4. 8. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  5. 9. Exploring future digitalised mobility adoption by utilising Lego as a mediating tool for research

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Magnus Eriksson; [2022]
    Keywords : Adoption; Participatory Design; Future digitalised mobility; Lego; Trustworthiness; Trust;

    Abstract : Due to the rapid digitalisation of mobility, and the emergence of cross-disciplinary businesses within the transport sector, transcending it from a traditionally product focused industry, into a service one. Therefore, the contextual understanding of mobility has become of even greater importance. READ MORE

  6. 10. Lid driven cavity flow using stencil-based numerical methods

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Hannes Juujärvi; Isak Kinnunen; [2022]
    Keywords : Finite differences; incompressible Navier-Stokes equations; lid driven cavity flow; benchmark problem; RBF-FD-LS; FDM; accuracy; computational cost; stream function-vorticity formulation;

    Abstract : In this report the regular finite differences method (FDM) and a least-squares radial basis function-generated finite differences method (RBF-FD-LS) is used to solve the two-dimensional incompressible Navier-Stokes equations for the lid driven cavity problem. The Navier-Stokes equations is solved using stream function-vorticity formulation. READ MORE
