Object 5 is an extrusion gauge holder. On the other side of the flat face in the photo is some machining that would not have been possible at all in NC. If it wasn’t 3D printed, it wouldn’t have been possible to make it this way. The internal design is done a certain way to optimize water flow and have a consistency of extrusion. The first prototypes were in PLA, and they lasted just a few hours. We tried PETG and something improved, but it tended to warp. With this we solved it.
Why 3D: To be able to do the machining that only additive manufacturing can do,
