![]() nanosats are a class of satellites with small dimensions characterized by low weight (between 1 and 10 kilos) and typically used for educational and research project they are usually referred in terms of CubeSat standard where (1 U is a 1 unit cube sat with a 10 cm 3 volume and maximum mass of 1 kg). Over the last decade, the space industry has seen an increased interest in small satellite missions and the recent advances in commercial-off-the-shelf (COTS) electronic parts miniaturization provided a valuable boost to the development of small spacecraft missions, usually based on nanosat and CubeSat satellites. ![]() 3D-printed parts were characterized via thermomechanical tests, outgassing tests of 3D-printed parts are reported confirming the outstanding performance of polyether ether ketone and its potential as a material for structural space application. The design phase includes the application of topology optimization to maximize mass saving and take full advantage of the ALM capability. This work aimed to realize a nanosat polymeric structure via FDM, including all the phases of the development process: thermomechanical design, raw material selection, printing process tuning, and manufacturing of a proof of concept of a technological model. As a high-performance technopolymer, polyether ether ketone (PEEK) has been adopted to fabricate parts via ALM however, the space compatibility of 3D-printed parts remains not demonstrated. However, the choice of the material is a crucial step of the process, as the final performance of the printed parts is strongly dependent on three pillars: design, material, and printing process. Moreover, provided that fused-deposition modeling (FDM) is used, nanosats and other structures could be easily produced in space. In this aim, polymeric ALM structures can become a choice, in terms of lightweight and demisability, as far as good thermomechanical properties. The use of additive manufacturing in spacecraft production is opening up many new possibilities in both design and fabrication, allowing for the reduction of the weight of the structure subsystems. ![]() Its bio-compatibility, bio-inertness, and high hydrolytical stability makes PEEK also ideally suited for surgical body implant applications.Recent improvements in additive layer manufacturing (ALM) have provided new designs of geometrically complex structures with lighter materials and low processing costs. In fact, PEEK is among the worlds highest performing thermoplastics and is widely used in the aerospace, automotive, and chemical industriesįor a multitude of engineering parts such as gears, bushes, friction bearings, shafts, ball valve seals, and small precision (rotational) parts. This material can replace steel in many applications. 1 However, it exhibits only moderate resistance to weathering due to damage caused by UV radiation.īecause of PEEK’s excellent mechanical properties, including high stiffness, high toughness, outstanding wear resistance, and long-term creep and fatigue resistance, mechanical parts made of Steam and can be used continuously up to 500☏ (260☌) with little or no permanent loss of its physical properties. Its exceptionally high resistance to hydrolysis in hot water and PEEK posesses high thermal stability, excellent chemical resistance, and ![]() ![]() The aromatic ring structure connected to ketone groups provides high modulus and long-term thermal oxidative stability whereas the ether linkages provide toughness, ductility and Semi-crystalline, cololess high-performance engineering Polyether Ether Ketone (PEEK) Properties and Applications ![]()
