How does the material feel? Slightly flexible? What temp? Where did you get that special filament?
I was toying with making wood block "stamps" with the laser burning down the negative. This looks bettah!
What are you going to do for backing and a handle of some sort? I've seen simple curved blocks, like a short piece of hand rail, as well as the classic vertical handle.
As a wood worker, I immediately wanna start in cutting, routing, and turning!
I am also playing with this as well. They are not small. These stamps are palm sized. I am using the cylinder backing for the lotus flower for its handle and a short handle for the butterfly to see what works.
Printed TPU feels just like rubber. The default settings worked fine 228C. They are really bendy with 20% infill. It is really stringy because it is so stretchy.
I did an experiment printing with the design down on the platform and design up and then sanding flat. At least with this material, for me, design down on platform is the way to go. Way flatter for the ink pad to coat evenly.
Playing around with a technique to make super fast stamps using Blender 3d.
A black and white shader to capture the shadows on a 3d model. I am lighting the render scene with an HDRI (image) so I can rotate to change the shadow direction and amount. It is analog so just the way I like it. Kentucky windage.
The shader nodes are in image below.
Once I have the image I can add a border with a 2d graphics program and then resave the image and import it into Blender to create a height map image.
