This looks great! I myself just bought a chinese 3d printer to prototype some parts. One thing I noticed was QA was difficult. If I did a run of 10k parts, how would you QA them?
We are able to get more consistent prints than a lot of people using their own printer, mostly because we've been able to build a lot of process around maintain and operation. So, for a given part, we'd make a sample for you to get approval, and then use that as spec. We regularly test printers to make sure they're operating normally.
Great! Sorry I didn't know whether or not to post to the root. I noticed you only had PLA and TPU materials. Is ABS in the works? My project required waterproofing and more strength than PLA.
