CubeSat - Think Inside the Box! · 模型 239929
Don't think outside, but inside the box! This design has two main ideas focusing in producing a standard frame for 1U CubeSat. The first is the ability of the structure to collapse or to extend. The intent is to print the structure in place in its collapsed state in an SLS 3D printer. This would allow for a one-piece frame to be printed, while 25% of the space a conventional 1U frame would take to print. This tackles one of the major disadvantages of most 3D printers, which is the slow speed in the z-axis. From experience with metal printers, increasing the scan area in the x-y plane by e.g. printing 4 frames in the space of one, will have a negligible effect on the overall print time, where a higher component will dramatically increase the print time. The design also takes advantage of the ability of SLS 3D printing to produce assembled components in-place. The second idea is the slide-in side plates. The intent was to create customisable cubes, where different geometries of side rails could be used depending on the mission of the cubesat. The side plates are held in place from the top plate. The location of the side plates is defined by a locking geometry on the sides. The top and bottom plate are flat based to also allow for easy customisation and are located by the 8 M2 screws, which also lock the structure in place. In order to increase the "locking" of the foldable members, they where designed with an interlocking feature. The relative arrangement of the foldable members with the slide-in side walls, allow for some space to be provided for solar panels on the outside of the cube, but without exceeding the geometric constraints. A final feature was the curved inside of the four main support rails, which reduce overall weight and allow for functional passages at the internal corners. The material used is aluminium, but it could be as easily produced with other metals used for SLS printing.
