One of the increasingly important ways that additive manufacturing<\/a> is being used in outer space<\/a> is for the creation of better parts for satellites. Satellites are critical for our way of life, with an estimated 9039 currently orbiting earth as of December 2023 according to the website Orbiting Now. These are used for everything from weather forecasting and television to internet communications and even GPS. That’s why innovation is so important in the sector, including for the glass optics which are so critical to satellite optical payloads. And now, it seems that there is yet more news coming out of about this. Through the iLAuNCH Trailblazer program, South Australia (UniSA), VPG Innovation and SMR will work on a new optical manufacturing process, called freeform optics, using additive manufacturing.<\/p>\n

As the name suggests, freeform optics are those that are free from constraints of symmetry in form and shape. Now, thanks to additive manufacturing, it is possible to design them by making complex shapes that can provide larger fields of view than the optics made by traditional manufacturing. This while still allowing for different sizes and enabling the parts to withstand the harshness of space. It is no surprise either that this is being done as part of the iLAuNCH Trailblazer program. It has been created specifically to help accelerate space innovation in Australia.<\/p>\n

iLAuNCH Trailblazer Executive Director, Darin Lovett expanded, \u201cThis project demonstrates what iLAuNCH is all about, taking a 2021 Defence Innovation Partnership (DIP) concept demonstrator that investigated the viability of Freeform Optical Components for small satellites \u2013 and moving it into production using Australian technology for real world application.\u201d<\/em><\/p>

Using Additive Manufacturing for Freeform Optics<\/h3>\n

Though we are of course mostly interested in the use of additive manufacturing in this project, and it is true that the technologies are a core part of iLAuNCH’s competencies, what is exceptional in this case is the combination of different technologies and processes to create these incredible parts. In fact, in order to create freeform mirrors for satellites, it will be necessary to combine additive manufacturing (which kind they do not specify, but iLAuNCH has a focus specifically on DED<\/a>) with traditional surface-finishing, vacuum coating and molding to create especially the mirrored surface necessary in optical applications.<\/p>\n

Dr. Stoehr explained, \u201cOur combined efforts will redefine the possibilities in additive manufacturing and freeform optics, promising a transformative impact on the future of space exploration. As we contribute our expertise, we are not just advancing technology but shaping a future where South Australia becomes synonymous with cutting-edge value-added manufacturing.\u201d<\/em><\/p>\n

Al Jawhari, the Co-Founder and Group CEO of St\u00e4rke-AMG, concluded:<\/p>\n

\n

\u00a0\u201cWith Australia developing new space capabilities and small satellite platforms, it is at the forefront of those developments, including the rising trend towards nanosatellite platforms. The iLAuNCH Trailblazer, in partnership with UNISQ, UniSA, St\u00e4rke-AMG, and SMR Australia, is an innovative journey pushing the boundaries of additive manufacturing to revolutionize emerging freeform optics technology. We firmly believe in the transformative power of additive manufacturing and its potential to positively reshape the manufacturing industry. We are proud to be leading those efforts that will enable innovative satellite optics design and manufacturing for Earth observation and other critical applications. Together, we are enabling a future where freeform optics will redefine the possibilities of space missions.\u201d<\/em><\/p>\n<\/blockquote>\n
