A new paper published in the journal Science demonstrates that audio recordings taken during 3D printing can be used to reverse engineer the design of the printed objects (archived). The technique demonstrated is limited in that certain settings like printer temperature are not collected in the audio recording, but there are other side channels by which this information may be obtained. This technique even allows reverse engineering designs from low quality smart phone audio recordings. Sorry for your loss.

Snore. Why the hell would anyone bother to do this? The printed object is a physical thing, can be '3d scanned', or even sliced with microtome and readily reproduced.
I would never underestimate the insanity that dominates retail and how it might make an odd course of action the most available.
The appeal of 3D printing isn't in having the design secret, quite the contrary.
If you were LVHM your answer would likely be very different.
But LVMH wouldn't use 3D printers, they would use """skilled""" workers.
Obviously, I welcome anything that can make fake "luxury" items. If all they have to sell is a brand, tough luck.
This is blindingly obvious to anybody who knows the basics of how stepper motors work.
…probably why this article was rejected by all the engineering journals.
