I work as a Prosthetic technician, and my interest in 3d printing started about ten years back, when the first (very crude) 3d printed devices surfaced.
I was intrigued by the possibilities, and bought my own 3D printer, to see if printing would make sense.
A lot of hype at that time, and at least what i could see was quite underwhelming. instead of the next big ting at work, printing became my hobby.
I followed development in this field, but could not see much real world products.
Last week i went to our main trade fair (OT World, Leipzig/germany) and was quite amazed about all the machines that where presented there.
There where a couple of belt printers for insole manufacturing, machines with big building volumes for seat cushions, i print farm from Mosaic, a print head for Prussa XL for continuous Carbon fiber and more. Just a couple of pictures, let me know if you have questions.
Good to see that finally there are some real world products!
