One of the key examples of our ability to combine additive manufacturing with mechanical components is the development of the POD 3U prototype, a system designed for the deployment of 10 cm CUBESAT-type satellites. This prototype, currently under development, aims to optimize the satellite launch and deployment processes within the aerospace sector.

The door opening and closing mechanisms were integrated with neodymium magnets, which were incorporated into the polymer structure through an additive manufacturing process. The door was attached to the structure using bolts, ensuring a robust and stable connection.

Satellite deployment is achieved using a spring that acts as a propulsion mechanism, pushing them with the help of a platform sliding on rails. To simulate the propulsion mechanism of the deployment, a similarity analysis was performed using a provisional spring, which allowed validation of the system’s behavior.

Design and manufacturing of a spring-release system for a 3-unit (3U) POD, intended to store and deploy three CubeSat satellites in a controlled manner. The design of precise and reliable release mechanisms is essential to protect the technological investment and ensure the success of space missions.

The final POD model was manufactured using 3D printing with PLA Plus, aiming to validate the geometry and assembly. Initial tests included structural verification, rail fitting, and door functionality.

Ejection speed measurements of the CubeSats were performed using an ultrasonic linear motion sensor. The obtained value of 1.32 m/s, through similarity analysis, aligns with speeds recommended by manufacturers.
