As MarkForged is still quite small, we all wear many hats. Today I spent a few hours doing a detailed failure analysis. It is important to document the process with good photographs and as my eyes get worse, I study the photographs to better see what is going on. In this case, our contract manufacturer failed to align a part properly before press fitting into another part. This resulted in the metal shavings that can be seen at the bottom of the receptacle. The loss of that material from the sides caused the press fit to fail allowing one part to rotate within the other. There is something very satisfying about solving a mystery and even more so when I get to use photography to help me do it.
