\"Cellular structures are lightweight structures with excellent mechanical, thermal, and acoustic properties. They offer promise in a series of applications, including lightweight applications, sandwich cores, mechanical damping, acoustic absorption, strain isolation, and thermal management. The manufacturing of these complex cellular structures is expensive and time-consuming, which hinders the adoption of these structures in many industries. Advancement in manufacturing technologies, such as additive manufacturing (AM), however, have changed this. AM allows for the rapid and less expensive manufacturing of complex cellular structures. This work aimed to investigate the performance of additively manufactured cellular structures for lightweight and sandwich core applications. In the present work, cellular structures were manufactured using an AM technique called laser powder bed fusion (L-PBF). Two L-PBF build parameters, hatch angle and build orientation, were investigated and optimized to manufacture defect-free solids. The optimized build parameters were used to manufacture different cellular structures, which were investigated as sandwich core structures. Non-traditional sandwich panels were manufactured using both the additively manufactured gyroid and diamond cellular structures. The performance of the non-traditional sandwich panels was compared against a traditional sandwich panel manufactured using an additively manufactured honeycomb core. Numerical models (unit-cell homogenization and unit-cell compression) were also developed to estimate the effective properties of cellular structures. The validated models were then extended to investigate the influence of additive manufacturing defects on the effective properties of cellular structures\"--Abstract, p. iv
