These instruments are far more resistant than traditional ones. 

The pictures below show resistance on 3D printed instruments produced by us.

We normally print instruments in one piece. For these one-piece instruments we haven’t yet found out their resistance limit (we still didn't to break one).

For the keyed instruments additional tests were made. You can see the results on the following video:

Keyed instruments also have a breaking point of course. The point of this video and tests is simply to show that they are at least, if not more, resistant as traditionally made instruments.
