(author)In this paper we are exploring the possibilities of 3D printing in the fabrication of mirrors for astronomy. Taking the advantages of 3D printing to solve the existing problems caused by traditional manufacturing, two proof-of- concept mirror fabrication strategies are investigated in this paper. The first concept is a deformable mirror with...article 2020

(author), Schnetler, H. (author), Snell, R. (author), Tenegi Sanginés, F. (author), Vega-Moreno, A. (author), van de Vorst, L.T.G. (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
