- Abstract
In the space sector reducing the cost through innovative designs, can be achieved through mass reduction and shorter development time. Additive layer manufacturing (ALM) is a process which enables, not only a new cycle of optimization in terms of mass and performance, but also a minimum lead time for small series production of complex parts. The objective of this paper is to design a part as light as possible while respecting the specific requirements. Specialized optimization tools were used in order to significantly reduce the number of design iterations. In order to cut down the mass furthermore, while increasing the stiffness, a hollow structure was considered. Internal cavities may raise a problem of powder evacuation in case of powder fusion processes. Concerning contamination problems of the spacecraft's (S/C) components, a powder removal procedure was closely developed with the manufacturer. As an outcome, a lighter space component with a lower production cost and fewer points of potential failure was obtained.
