(author), Mirzaei, S. (author), Keckes, J. (author)Additively manufactured multi-metal hybrid structures can be designed as functionally graded materials providing an optimized response at specific positions for particular applications. In this study, liquid dispersed metal powder bed fusion is used to synthesize a multi-metal structure based on Inconel 625 (IN625) and stainless steel 316L ...article 2022

(author)A possible answer to the challenge brought by the construction of the next generation 40 m-class telescopes was the case study of FAME (Freeform Active Mirror Experiment). As the new instruments typically increased in both volume and complexity, the use of highly aspherical freeform surfaces could be a great solution as these systems are built...conference paper 2020

(author), MezA, G. (author), Beardsley, M. (author), Harris, M. (author)Additive Manufacturing (AM; 3D printing) for mirror fabrication allows for intricate designs that can combine lightweight structures and integrated mounting. Conventional lightweight structures utilise cubic or prismatic unit cells, which do not provide uniform support at the edge of curved mirrors. We present a new circular lattice based upon...conference paper 2020

(author), Hugot, E. (author), Vega-Moreno, A. (author), Tenegi Sanginés, F. (author), Dufils, J. (author)Additive manufacturing (AM) methods and post processing techniques are promising methodologies considering that it is now possible to print in a wide variety of materials using processes much refined from those originally available twenty years ago. To date the uptake of AM in Astronomy is relatively low compared to other application areas,...conference paper 2020

(author), Burssens, J.W. (author), Chen, J. (author)Packaging of semiconductor chips, especially MEMS-based, always causes stress on the functional areas of the die causing unpredictable changes in chip performance. As a consequence such devices can only be calibrated individually after complete assembly. Melexis and TNO have developed an approach to reduce significantly packaging stress effects...conference paper 2012
