As you can imagine, a few parts came back and didn’t fit, costing us hundreds of pounds, and weeks in lost build time.
The other alternative for components like this would be to send one for manufacture, receive it to check the fit, then go ahead with the remaining parts. However, this again is fairly unfeasible due to time constraints, and would still have cost hundreds for the single brake bell to be potentially wrong.
Ultimately, if the whole set of bells were incorrect, it would have cost us something in the region of £2,000. Robox, in comparison, used around £2 of plastic, and reduced prototype time to a single day.
We can realistically say that our Robox printer paid for itself with this one job! -Matt Scott, Design Engineer
