Robotic flexible cell for additive manufacturing of heat shieldsWatch the animation below in the URL.UPDATE:Videos:- Cell View: https://youtu.be/xLRZxteKpBY- Animation with the printing process: https://youtu.be/lMGl2Qd_33M- Animation with all stages: https://youtu.be/I9xgz5Tugf8DescriptionIn the following robotic cell for NASA challenge there are two gantry robots with linear motion for the additive manufacturing of a spacecraft thermal protection heat shield. The two robots are modified both in length and width for a larger workspace so they can print. The two robots have 3 DOF (degrees of freedom) on X, Y, Z. The movement of the robots is linear and the printing process is circulating on the circumference of heat shield ascending each layer. The material is supplied from a container through the cables to the head printer. The material cords are supported by two piedestals to prevent robots from getting tangles in the cables.Process description with all stagesThe gantry robots begin the printing process, they are equipped with head extruder for material distribution, and at the end of the robot printout the robots retract to the HOME position. After finishing the printing process, the gateway opens. The worktable with the part moves linearly using rail guideways, when the table reaches the end of the rail it stops. The human operator enters the respective station where the table is located, the photoluminescent barrier detects its presence and the gateway closes automatically. The operator mounts the piece through a crane via chains, the crane raises the piece into the air and moves to an interpost to deposit the piece. The printing process is repeated.
