With the goal of producing critical components for its industry-first satellite innovation – OneSat -, Airbus Defence and Space called on 3D Systems’ Application Innovation Group (AIG). Those application engineers have already demonstrated their expertise in the design and manufacture of other critical components such as this 68 kg (149Lbs) 3D printed Titanium Gearbox. Furthermore, they already have certain experience in working with Airbus, and in this specific field of activity. In their previous collaboration, they developed and produced the first 3D printed radio frequency (RF) filter tested and validated for use in commercial telecommunications satellites and the production of innovative switch assembly network designs for two Eurostar Neo spacecraft as part of the first large-scale deployment of RF products using direct metal printing. That was five years ago. Furthermore, another argument that weighs in favour of 3D Systems is the part quality achievable with its DMP systems.
As part of this project, the AIG team has designed an end-to-end additive manufacturing solution – comprising materials, 3D printing technology, software, and applications expertise – to produce the components required for the large antenna array on these satellites. Those RF Components are said to be installed in the First Fully Reconfigurable Satellite.
Each OneSat satellite requires two large antenna arrays, one to transmit signals and one to receive. 3D Systems’ DMP Factory 500 Solution will be employed for serial production of the antennae components using LaserForm AlSi10Mg and specific parameters developed by the AIG for this application to achieve the required 30µm layer thickness. The DMP Factory 500 was selected for this project based on its build volume (500mm x 500mm x 500mm), accuracy, and rapid print speed. The intelligent multi-laser configuration of this printer enables the production of seamless large parts resulting in the highest surface quality with outstanding material properties. The printer includes a unique vacuum chamber that allows for the lowest possible oxygen (O2) content in the build chamber protecting chemical composition and reducing the moisture content of the metal powder alloys during manufacturing. This ensures optimum operating conditions for consistent part quality (e.g., mechanical properties and surface homogeneity), which is necessary for an industry with such high requirements for quality and precision. The DMP Factory 500 also includes 3DXpert® which supports every step of the additive manufacturing workflow from design to post-processing, to quickly and efficiently transition from a 3D model to successfully printed parts, a press communication reads.
In addition to providing design and production expertise, 3D Systems’ Application Innovation Group is also acting in the capacity of project manager. The company has identified subcontractors that are conducting post-processing and quality inspection, thus delivering a comprehensive end-to-end solution designed to help Airbus Defence and Space mitigate risk and reduce time to market. The AIG is also leading the technology transfer process, whereby they will enable another tier 1 supplier to quickly ramp production of these fully-qualified components. The supplier is also purchasing another DMP Factory 500 to complement its existing fleet and allow it to meet the quality levels required by Airbus.
“OneSat is a truly disruptive product, and we wanted our design and manufacturing process to possess that same level of innovation,” said Stephen Phipps, OneSat antenna program manager, Airbus Defence and Space. “Our company has a strong partnership with 3D Systems and has relied on its team of application engineers to help us bring our most advanced designs to life. Everything from the quality of the parts produced using their printers, through to parts qualification, quality management, and overall project management have helped Airbus Defence and Space maintain its position as an industry leader.”
