Using sub-par materials and inaccurate dimensions does not sound like the appropriate start to a precision engineering project. However, a team at Sandia National Laboratories has done just that, and made a functional telescope capable of “seeing” as accurately as one five times the cost. How did they do it? By leveraging the advantages of design for additive manufacturing (DfAM). Movement of the
