  4. 3. Product-development for laser powder bed fusion

    University essay from KTH/Produktionsutveckling

    Author : Ludvig Dagberg; David Hu; [2023]
    Keywords : Laser Powder Bed Fusion; Additive Manufacturing; DFAM; Selective Laser Melting; Design for Additive Manufacturing; Laser beam fusion;

    Abstract : This thesis investigates the differences in the design process when developing a product for additive manufacturing (AM) compared to traditional manufacturing methods, such as CNC machining. In recent years, additive manufacturing (AM), including metal-based laser powder bed fusion (L-PBF), has gained popularity, leading to increased adoption by companies. READ MORE

  5. 4. Adaptable housing during crisis : Sustainable transition from tents to permanent accommodations.

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Alex Dam; [2023]
    Keywords : Modular housing; Crisis management; Sustainability; Thermal comfort;

    Abstract : This study delves into the development of a long-term, sustainable housing solution to address the challenges faced during crisis when people are in immediate need of an accommodation. While temporary tents have been traditionally employed as shelters, their inefficiency in colder climates and lack of sustainability necessitate the exploration of alternative options. READ MORE

  6. 5. Analysis of Footbridge Comfort Vibrations

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Niklas Thuresson; Henrik Ruuth; [2023]
    Keywords : footbridges; dynamics; vibrations; accelerations; Sétra; comfort vibrations; natural frequencies; Technology and Engineering;

    Abstract : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. READ MORE
