  3. 2. Influence of Post-treatments on Corrosion Properties of 3D printed Metal Components for Bioprocessing Applications

    University essay from KTH/Materialvetenskap

    Author : Leyla Koort; [2023]
    Keywords : PBF-LB 316L; surface post-treatments; as-built; tumbling; Hirtisation; DLyte; electropolishing; chemical milling; pitting corrosion; CPT; cyclic potentiodynamic polarisation curves; immersion test in 1M NaCl and 1M NaOH;

    Abstract : Additive manufacturing (AM) has the potential to overtake the conventional production of pipe systems of stainless steel grade 316L intended for bioprocessing applications by utilising powder bed fusion laser beam (PBF-LB) technologies. However, challenges such as high surface roughness need to be overcome and corrosion properties improved to meet industry standards. READ MORE

  4. 3. Mechanical properties of WE43 : Finding optimized process parameters using PBF-LB for enhanced properties of the magnesium alloy

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Fanny Saarela; Fanny Sandblad; [2022]
    Keywords : biomedical engineering; materials science; additive manufacturing; powder bed fusion laser beam; PBF-LB; magnesium; magnesium alloys; WE43; mechanical properties; scan strategy; layer rotation; build direction; build orientation;

    Abstract : When skeletal fractures are too extensive for fixation with plates and screws, autografts are the most used technique for treating this. Within the biomedical field the interest in biodegradable implants made from additive manufacturing have increased. Magnesium alloys has also gained interest because of its favorable mechanical properties.. READ MORE

  5. 4. Investigation on how additive manufacturing with post-processing can be used to realize micronozzles

    University essay from Uppsala universitet/Ångström Space Technology Centre (ÅSTC)
