Producing extreme light weighted structures by combining a new design concept with the most recent production machines and production software tools. Weight reductions of up to 50% compared to the traditional techniques are feasible with the same stiffness performance. Suitable for standard materials like aluminium and steel, for single construction parts out of mono material and with a single production process. Astronomical instruments for space applications and ground-based applications require more and more extreme light and extreme stiff structures. The traditional technique like 3-axis or multisided machining of metal parts seems limited and not suitable for the next generation instruments. New materials with new production technologies are used more and more with all their specialties and restrictions. ASTRON developed a new structural design of traditional materials with heritage optimized for production with the most recent milling machines. The structural shapes are closely linked to the extremes of 5-axis simultaneous milling. The design and production process is patented and now free for publication.
