Hi Guys, Currently I have a gripper system in a robot to hold plastic bottles by the neck, the system consists in a silicon sleeve that get compressed (from top to bottom) then the outer diameter increases (catching the bottle by the neck). I am considering in 3D print similar sleeves but using a different material. I try making some parts with TPU but is still too rigid, any ideas about a good material? Any thoughts on IROPRINT™ F 80213? Thanks!
