Sorry if I'm driving you crazy but I'm obviously intrigued by your projects.
That's a clever way to get an "overmolded" part. I'm kind of surprised the material will fuse to itself after pausing. How does this work? Does the new layer carry enough heat to "melt" the previous layer? Does the whole part need to be heated during printing?
Can you actually get some adhesion to the washer? Not needed in this application but I'm curious if you can get enough of a bond to stress the metal/elastomer interface without it coming apart?
How do the TPE material properties seem to compare with original rubber(?) parts? Can you get a range of durometers? Any info available to you about durability (ie cyclic stress, UV, chemical stability, etc.)?
OK, OK.... yes I should go look it up!!
