1. 6. Cryogenic properties of additive manufactured austenitic stainless steels for space applications

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Patricio Piantanida; [2023]
   Keywords : austenitic stainless steel; additive manufacturing; cryogenic;

   Abstract : The mechanical properties of three austenitic stainless steel alloys, namely 21-6-9, 316L and a modifed 316, fabricated via laser powder bed fusion, have been studied. From the results previously obtained through tensile tests at room and cryogenic temperatures, their strength and ductility were compared against similar conventionally processed materials.

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

4. 8. 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

5. 9. Process characterisation of an additive manufacturing equipment : An analysis of the effect of electron beam powder bed fusion process parameters on the melt pool geometry and microstructure of Ti-6Al-4V

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Ida Ljusell; [2023]
   Keywords : Additive manufacturing; AM; 3d printing; titanium; process characterisation; electron beam powder bed fusion;

   Abstract : Additive manufacturing (AM) are manufacturing methods where components are produced by adding material layer by layer which allows for a high freedom of design as well as little or no material waste compared to conventional manufacturing methods. Despite the many benefits of AM there are still problems concerning the quality of the produced material. READ MORE

6. 10. Comparative investigation of micromechanisms of plastic deformation by in-situ tensile tests of highly textured 316L steel

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Subhani Kumarasinghe; [2022]
   Keywords : Additive manufacturing; texture control; plastic deformation;

   Abstract : Additive manufacturing (AM) is identified as one of the best techniques in manufacturing components addressing most of the current challenges including material scarcity, design complexity, material compatibility, etc. Stainless steel 316L is one of the promising material candidates in AM due to its extraordinary properties that are useful in a wide variety of industries.
