'''Title:''' A Cubesat’s hinge re-design for Selective Laser Melting

'''Authors and full affiliations:''' Alberto Boschettoa , Luana Bottinia , Valerio Cardinia, Marco Eugeni a, Paolo Gaudenziaa , Gabriel Graterol Nisib, Francesco Venialiaa, aDepartment of Mechanical and Aerospace Engineering, University of Rome “La Sapienza”, via Eudossiana 18, 00184, Rome, Italy ; ,bSmart Structures Solution, Via Luciano Manara 51, 00153, Rome, Italy .

'''Keywords:''' CubeSat; Design for additive manufacturing; Design for assembly; Nanosatellites ;Selective Laser Melting.

'''Purpose:''' This work points AM out as a key technology allowing for a drastic reduction of the part count for a mechanical system, taking Design for Assembly (DFA) guidelines to the extreme. It underlines the need to consider AM-related constrains already in the design phase, such as the clearance and the shape of the hinge and the snap joint matching SLM specific constraints such as support structures design and removal planning, part orientation in the building platform, and hollowing out for powder removal.

'''Methodology:''' This paper follows the Design for Additive Manufacturing (DFAM) and Design for Assembly (DFA) methodologies.

'''Findings:''' The already-assembled, fasteners-free mock-up demonstrates AM as a key technology to take DFA guidelines to the extreme. The increased complexity of the parts, integrating the features and the hinge, does not compromise the fabrication process. Considering the assembly-related cost saving entailed in a part-consolidated design, this works makes AM closer to the small satellites market, envisioning constellations made of many satellites.

'''Benefits:''' The structure is made of two parts joined by a hinge, making the system an already assembled one. In this way there was an assembly-related cost saving.
