UPDATE Aug 23, 2018: New animations in gif, avi, and mp4 formats (folder: Animations) have been added, but some may not be visible in the library. The complete animation is on YouTube (https://youtu.be/uoorVftBJCk). Modifications were made to parts like Robot_Tool_5 for improved process velocity. This configuration speeds up Avcoat material application. Overall, processes are faster now. All tasks are included. If you have any questions, please contact me. First entry on Aug 9th, 2018: Submission for "NASA Challenge: Human Rated Spacecraft 3D Printing Process Animation". Before viewing the renderings, video, and poster, check attached files/folders: CAD (Solidworks, STEP, STL, FBX), Full_Model.zip, Images (Renderings), Animations (NASA_CHALLENGE_SALAZAR.mp4), Poster (NASA_CHALLENGE_SALAZAR.pdf). Video transcript: This video demonstrates my vision for manufacturing the Orion spacecraft's heat shield and pressure vessel. It meets NASA requirements. The model shows additive manufacturing processes for both components, along with assembly and storage of Orion capsule parts. Selective laser melting technology is used for the metal pressure vessel structure due to its advantages in dimensional accuracy, surface finish, and mechanical behavior compared to other methods. Powdered metals like titanium, cobalt chrome, aluminum, or stainless steel are used as raw materials. The model is sliced into layers, and a laser fuses the metal powder layer by layer. For the heat shield, two robotic arms use fused-deposition modeling (FDM) to print composite material with different printing heads. In FDM, filament of raw material is extruded above its glass transition temperature to create desired geometry. The heat shield concept involves producing a thin metal layer using selective laser melting, then printing the honeycomb matrix and applying Avcoat epoxy resin individually to each cell. Assembly occurs over the selective laser melting machine, and distribution uses rail-guided on-the-floor vehicles for equipment movement. The factory is designed for automation with flexible manufacturing systems and minimal manual intervention.
