1. 6. Optimisation of the gas atomisation process used in aluminium powder production : To improve morphology by minimising satellite formations

   University essay from KTH/Materialvetenskap

   Author : Henrik Hedlin; Johan Nymo; [2023]
   Keywords : ;

   Abstract : There exists a lack of information and an exact understanding of the gas atomisation process resulting in the use of trial and error methods in the industry. The lack of information is the result of the difficulties in observing the actual process as it occurs, something that the use of computational fluid dynamics may be able to substitute. READ MORE

3. 7. 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. 9. 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

6. 10. Material selection and topology optimization of a shift fork for metal 3D printing

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Rahul Amaralapudi Bala Vardha Raju; Raja Surya Mahesh Thammisetty; [2022]
   Keywords : Additive manufacturing; Topology optimization; Finite Element Analysis; SIMP; Generative design;

   Abstract : In collaboration with Kongsberg Automotive, the thesis focuses on material selection and redesigning the shift fork for additive manufacturing using topology optimization. The shift fork is a component in the gear shifting mechanism in the automotive industry. The current shift fork at Kongsberg is manufactured from aluminum using die-casting. READ MORE
