The complexity of components fabricated in today's industry is ever increasing. This increase is partly due to market pressure but it is also a result from progress in fabrication technologies that opens up new possibilities. The increased use of additive manufacturing and multi-material systems, especially, has driven the complexity of parts to new heights. The new complex material systems brings benefits in many areas such as; mechanical properties, weight optimisation, and sustainability. However, the increased complexity also makes material integrity investigations and dimensional control more difficult. In additive manufacturing, for example, internal features can be fabricated which cannot be seen or measured with conventional tools. There is thus a need for non-destructive inspection methods that can measure these geometries. Such a method is X-ray computed tomography. Computed tomography utilizes the X-rays ability to penetrate material to create 3D digital volumes of components. Measurements and material investigations can be performed in these volumes without any damage to the investigated component. However, computed tomography in material science is still not a fully mature method and there are many uncertainties associated with the investigation technique. In the work presented in this thesis geometries fabricated by various additive manufacturing processes have been investigated using computed tomography. Also in this work, a dual-energy computed tomography tool has been developed with the aim to increase the measurement consistency of computed tomography when investigating complex geometries and material combinations. / MultiMatCT

The aim of this work is to explore the printed Hawaii shirt through material investigations in search of new print meetings. A vital step for this investigation was to develop the classic Hawaii- prints and motives in mixed media. Followed by exploring alternative printing techniques such as transfer printing, laser cutting and knitting in different materials to reach new expressions yet keeping a clear reference to the Hawaii shirt. The intention of this work was to investigate how the Hawaii shirt with its classic print could interact with the mind and body of the wearer. Furthermore, to question the informal rules of wearing a Hawaii shirt with a starting point in Umberto Eco’s theories about epidemic self-awareness. The motive of this work is to critically look at the society today, with a focus on consumerism, foreign travel and tourism and the expression of it, with the Hawaii shirt as a symbol of these things. Based on the assumption of the Hawaii shirt being a tacky souvenir that tourists bring back home from their holidays. This work show new expressions of the printed Hawaii shirt through innovative print meetings. This work also proposes alternative ways of wearing a Hawaii Shirt.
