Use of 3D printing in astronomical mirror fabrication

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...

An additive manufactured CubeSat mirror incorporating a novel circular lattice

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...

H2020 opticon project overview: Investigating the use of additive manufacturing for the design and build of multi-functional integrated astronomical components

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,...

Nutritional impacts of different whole grain milling techniques: A review of milling practices and existing data

The majority of whole grain flour is produced using modern milling techniques, usually with steel rollers, in which a batch of grain is separated into multiple millstreams, sifted, and recombined. In some cases constituent millstreams are purchased and combined by a supplier or end user to achieve a reconstituted whole grain flour or meal with...

Human automation integration

Many versions of future concept of operations (CONOPS) rely heavily on UMVs. The pressure to take the human out of immediate control of these vehicles is being driven by several factors. These factors include a reduction in cost for the production and maintenance of the vehicle, operational viability in extreme environments, and the public...
