Direct manufacturing technology has advanced rapidly in the last decade. Along with advancements in the technology, come advancement in the application towards functional structures. This work examines the functional application of laser direct manufacturing towards the creation of complex and unique, small satellite structures. Utilization of direct manufacturing techniques are shown to greatly reduce cost and lead times for procuring metallic hardware. Additionally, this project demonstrates how frequent design iterations are possible since fabrication is solely dependent on a three-dimensional solid model. Finally, this work shows how wide-scale adoption of direct manufacturing technology might have a far-reaching impact on future space structure designs.
