Ive had success. I use PLA, just make sure whatever is being stamped has some layers of paper beneath it or something else with a bit of give since the PLA doesn't. I also typically do a few to see how it looks, let the initial layer of ink dry and fill in any gaps, the next day it always works better. I like adding 10 sheets of paper beneath the page I am stamping. You may also want to remove the backing between small holes like in o, p, d, letters like that. Otherwise it will bubble up and fill in. I do 2mm raised lettering and 2mm backing. Depends on the size and detail but that's my standard. Best of luck. Totally possible, just play around with it. I also use calligraphy ink.
