It ended up being solid just because of the standard wall thicknesses, but PLA prints are quite strong from a compressive standpoint. That said, I am sure I am not applying the entire 6 tons. I have done similar experiments with a bench vice with similar results too, it’s just a little harder to line everything up give the jaw depth.
Here’s a picture of the stamp.
It’s just a 3mm thickness disc with the picture on the top at 2mm. I use a 6 ton shop press to compress it with a 1" steel plate used to distribute the force. The print is a no name brand black PLA printed at 0.2 at the fast setting on an AnkerMake M5. You can also see the residual ink, the stamping only takes a small amount. I did a few at one time without having to reapply.
One of my favorite character and was the inspiration for the stamp for sure.
I make some small things for gifts and being able to make a custom stamp for a few uses is a cool concept.
I went over the stamp with blue sharpie and wet the leather with water and a small amount of isopropyl alcohol. When you compress the stamp into the leather with a press the alcohol reactivates the ink in the recesses.
This was my first attempt with a 3d printed stamp. Worked great!
For sure. I just dragged and dropped the jpg into 3d Builder. That program is rudimentary but if it is a simple drawing it does a great job creating a model.
