cubesat ARM-IT

The ARM-K1 Cubesat boasts a scalable and flexible design, minimizing parts, height dimensions for FDM printing, material costs, and errors. It features self-production of custom solar panels through FDM printing. The fixing system omits screws, using an alternative method with screws reserved for standard solar panels. The twin element skeletons are permanently glued together. Measuring PC104 form factor, it accommodates Arduino and Raspberry Pi satellite experiments. Its building process utilizes FDM to make technology accessible for experimentation. Nylon and carbon fiber compose the skeleton, demanding high precision (±0.04mm), rigidity, but not flexibility. Nylon comprises shell panels and U connectors, requiring medium precision (±0.08mm) and medium flexibility. Post-treatment includes verifying and correcting contact zones and metallization in a vacuum to remove oxygen. 1U parts consist of 2 skeletons and 4 shell panels; 2U parts incorporate 4 skeletons, 8 shell panels, and 1 connector; 3U parts include 6 skeletons, 12 shell panels, and 2 connectors. The twin skeleton elements of a 1U differ except for the hole area of the fixing zone for PC104 tabs, occupying a combined volume of 70 cubic centimeters.
