1. 11. Defect classification in LPBF images using semi-supervised learning

   University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

   Author : Anton Göransson; [2022]
   Keywords : Additive manufacturing; Laser powder bed fusion; Machine learning; Siamese neural networks; Deep learning; Defect classification;

   Abstract : Laser powder bed fusion is an additive manufacturing technique that is capable of building metallic parts by spreading many layers of metal powder over a build surface and using a laser to melt specific sections of the surface. The part is built by melting consecutive layers on top of each other until the design is completed. READ MORE

3. 12. 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

4. 13. Powder Rheology within AM production : Evaluating Compressibility, Permability, & Aeration for 316L Powders Within SLM Processes

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : André Leo; [2022]
   Keywords : Powder rheology; AM; Additive manufacturing; BPF; Powder bed fusion; SLM; Selective laser melting; FT4 powder rheometer; Compressibility; Permeability; Aeration; Pulver reologi; AM; Additiv tillverkning; BPF; Pulver bed fusion; SLM; Selektiv lasersmältning; FT4 pulver reometer; kompressibilitet; permeabilitet; luftning;

   Abstract : Additive manufacturing with the use of metals have been a steadily increasing field, being able to create products with a higher degree of complexity than traditional processing techniques. SLM is a popular AM process that uses metal powder as feedstock, and one of the key components of this process is the powder rheology. READ MORE

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

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

   Author : Alan Bugurcu; [2022]
   Keywords : additive manufacturing; micronozzle; micro rocket nozzle; laser-powered powder bed fusion; electropolishing; supersonic micronozzle; supersonic micro rocket nozzle; titanium alloy; titanium-64; Ti-Al6-V4;

   Abstract : This is predominantly a qualitative study on the manufacturing of micronozzles with an additive manufacturing (AM) technique, namely the laser-powered powder bed fusion (PBF-LB).  Manufacturing of micronozzles with standard microelectromechanical system technology often results in 2.
