This paper is intended to be a study in the applications of the design freedom granted by additive manufacture in the design of a 1U CubeSat frame. The main loads experienced by a CubeSat are structural (during launch) and thermal (solar radiation). Beam charging is an emerging technology which involves charging a CubeSat using a laser beam. In this paper, a CubeSat frame was redesigned to account for the structural loads induced during launch and the thermal loads induced when beam charging. The thermal, weight, design, and structural requirements for a new CubeSat design were derived. The 1U CubeSat frame was redesigned using a topology optimization. FEA tests were run to validate the thermal and structural properties of the frame. A panel was added to the frame to serve as the thermal dissipation system. FEA tests were run to validate the thermal and structural properties of the panel. A lattice was added to the panel, and it's impact was quantified. The frame and panel were both printed on a SLM 125 HL.
