@zapta Hello Zapta,
the prostheses are completely personalized.
There are two ways to make the sockets. The technician who is in Africa, take the scan of the patient's stump or with the plaster, he makes the mold of the child's leg, he makes the corrections and then sends it to me by internet. I do the modeling with the software and I set the G-code and I send it to the technician who will print it at home.
If anyone is doubting the accuracy or repeatability of such probes, I submit the following bed mesh of a RailCore 300ZL for discussion. This comes from a user who I was helping comission their printer with Duet3 hardware.
I condensed the data into the orange box since the screen aspect ratio was so high and hard to read.
