How can I 'stamp' a fingerprint onto an object's geometry for 3D printing I need to make a pendant (jewelry) with a fingerprint pressed into it — this will then be 3D printed (see image attached for an example of what I'm looking for).

Am I correct in thinking that a displacement modifier is the way to go? I have the image of the fingerprint which I was then going to use as the displacement modifier on the object. I have tested this out and it works to a certain extent but I was just wondering if there was a better method for doing this?

Many thanks in advance for any help or advice on this.
I would think displacement is the way to go. An alternative would be to try making a textured sculpt brush with the texture set to stencil and use Dyntopo.
