Sophisticated automated workflow, supported throughout by customer service
I love the automated workflow, Xometry used my CAD files directly without export, and displayed everything it detected: end product, what manufacturing process; I did need an external note for drilling and tapping, but I could even upload different versions to see which was the most manufacturable. Then during manufacturing there were several variances, and customer service was so easy to deal with; one was my own screw-up, I failed a fit-check and Xometry was able to intercept the order and change out the drawing; another was a misunderstanding at the machine shop that I accepted; another was that my design wasn't manufacturable and a different process was substituted. I was communicating with cognizant representatives all the way through.
