Whilst the benefit of additive manufacturing (AM) in rapid prototyping becomes more and more established, the direct application of 3D printed part is still demanding. Exploitation of AM opens the door for complex and optimized parts which are otherwise impossible to fabricate. In the meanwhile, specific knowledge and aspects in analysis and design process are still to be explored. For a fixed target vector scanning diffractometer [1] at SwissFEL we developed, manufactured and tested a 3D-printed sample holder with carbon fiber reinforced plastics material. The diffractometer for serial crystallography is dedicated to collect diffraction patterns at up to 100 Hz on many small crystals (< 5 µm) by scanning the sample support in a continuous, arbitrary motion. The high dynamics arising from curved trajectories in the xy-plane requires a light and stiff sample holder which attaches the sample to the stage. In addition to 3D printed parts, an aluminum counterpart produced by CNC machining has also been tested and carefully evaluated. Our work in the course of development process on topology optimization, design, manufacturing and dynamic verification tests will be presented.
