6. Optical Topographical Characterisation for Flexographic Printability
Sammanfattning : The flexographic printability is largely dependent on the topographical characteristics of the substrate. OptiTopo is a recently developed optical imaging technique, which provides precise and fast topographic scans of both printed and unprinted paper surfaces. LÄS MER
7. Degradable copolymers in additive manufacturing: controlled fabrication of pliable scaffolds
Sammanfattning : Inom vävnadsregenerering är produktionen av väldefinieradematriser med en porös arkitektur av nedbrytbara polymerer av stortintresse, dessa kan nu skapas genom additiva tillverkningsprocesser. Vidadditiv tillverkning krävs ett smalt munstycke för att skapa detaljrikastrukturer och detta ställer krav på att de reologiska egenskapernaanpassat. LÄS MER
8. Engineering 3D degradable pliable scaffolds for adipose tissue regeneration : Advancing cell-material interactions by understanding the influence from thermal, chemical, mechanical properties and scaffold design
Sammanfattning : In soft tissue defects that arise due to trauma, tumor resections and complex burns, a significant loss in adipose tissue remains a considerable challenge due to the insufficient regenerative capacity of the tissue. This thesis focuses on assessing cell-material interactions between degradable 3D polymer scaffolds with different designs and adipose tissue-derived stem cells. LÄS MER
9. Laser-based powder bed fusion of stainless steels
Sammanfattning : The aim of the present work has been to widen the knowledge of how variations within powder manufacturing affect laser-based powder bed fusion processing, and how this processing affects the microstructure and strength of stainless steels. The approach was to keep the processing parameters fixed while the powder feedstock was varied. LÄS MER
10. The Effects of Morphology and Surface Oxidation of Stainless Steel Powder in Laser Based-Powder Bed Fusion
Sammanfattning : Laser based-powder bed fusion (LB-PBF) is one of the many techniques within additive manufacturing (AM) that allows for near net shape manufacturing of metallic components. By using powder feedstock, it is possible to spread thin layers of powder and further selectively fuse powder in a repetitive manner until the component is completed. LÄS MER
