Bob,
Thank you for this information, it has convinced me that I need to go the Resin path and not the filament for my 3D Printing leather stamp needs.
I have a few suggestions if you don't mind on the laser engraving which I have been doing for a couple of years now.
I see that there is some over smoky burn edges during the engraving.
A simple solution is to place a piece of low tack masking tape over the area that you will engrave on, so when the engraving is done you lift away the tape and you will have crisp engraving edges.
Some people also like to wet the leather, actually more like damping it before engraving it. I haven't gone that route because the tape works for me but just an FYI.
And if your laser engraver has the ability to do so you can add an air assist that will blow unto the area being engraved and that will also prevent the smokey over burn.
Hope this makes sense, thanks again for your info on the resin printer, I can't wait to get one.
Roger
