This research investigates a means of negating such shortcomings and reaping the benefits of both LPBF additive manufacturing and traditional manufacturing methods by joining such parts together using laser welding in the autogenous mode (no fillers required). Based on the literature review conducted in this field and the gaps identified, a two-stage methodology was utilised, as per following.

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. Additively manufactured TPU mould is developed to cast complex concrete structures. A planar topologically optimized cantilever and a free-form 3D column are cast using the proposed TPU mould. Good surface quality is obtained for the cast concrete elements, and the moulds can be reused many times after cleaning.

The recent advances in the study of the unique capabilities of monolayer crystals had predicted piezoelectricity in two-dimensional (2D) group IV chalcogenides which are not present in their bulk forms. In this study, the predicted piezoelectric properties of was experimentally explored through Piezoelectric Force Microscopy (PFM). Tin Sulfide (SnS), Tin Selenide (SnSe), Germanium Sulfide (GeS), were exfoliated from their bulk forms by the top down methods of liquid sonication, while and Tin Disulfide (SnS2) mechanically exfoliated by tape.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.
