  1. 1. Conditioned 3D-printed polyamides for structural optimization : Establishing the material data to advance in AM utilization

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Philip Olsson; [2022]
    Keywords : Additive manufacturing; selective laser sintering; multi jet fusion; moisture; temperature;

    Abstract : Polyamides are commonly used in additive manufacturing for final part production, but the material performance can be affected by environmental conditions. The purpose of this project was to evaluate the effects of moisture and temperature on 3D printed polyamides and how structural optimization can benefit from condition-specific data. READ MORE

  3. 2. Post-processing for roughness reduction of additive manufactured polyamide 12 using a fully automated chemical vapor technique - The effect on micro and macrolevel

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ingrid Johansson; [2020]
    Keywords : Chemical post-processing; PostPro3D; selective laser sintering; surface roughness; polyamide 12; Kemisk efterbehandling; PostPro3D; selektiv lasersintring; ytojämnhet; polyamid 12;

    Abstract : Additive manufacturing has increased in popularity in recent years partly due to the possibilities of producing complex geometries in a rapid manner. Selective laser sintering (SLS) is a type of additive manufacturing technique that utilizes polymer powder and a layer-by-layer technique to build up the desired geometry. READ MORE

  4. 3. Metal Filament 3D Printing of SS316L : Focusing on the printing process

    University essay from KTH/Maskinkonstruktion (Avd.)

  6. 5. Audi Uno : A symbiotic car

    University essay from Umeå universitet/Designhögskolan vid Umeå universitet

    Author : Gaurang Nagre; [2016]
    Keywords : additive manufacturing; future mobility; transportation design; Audi; car design; styling;

    Abstract : Abstract When we paint a nebulous future of tomorrow based on the research dictated by the available resources, we see a marathon run for the future that instigates new opportunities for the automotive industry with additive manufacturing. Cars of today are a product of subtractive manufacturing; but in future 3D printing would empower us to define a novel architecture that provokes the construction of the interior, exterior and the powertrain in one piece allowing us to celebrate the marriage between all three key components.
