3D printing and raw earth plaster

I staid a long time without posting, but not without blending, nor printing !
Here is one of the experiments I made for a workshop with children:

I took the idea of the old rubber rolls for printing I found in my house, and adapted it to 3D print. And as I love raw earth buildings, I used it to make some drawings on raw earth plaster:
First step is modelling in Blender the roll, then put some drawings on it (with sculpt mode or here with procedural textures): It’s a basic cylinder with hole in it to mount it on a handle. A lot of subdivision on the outside and a displace modifier with some procedural textures.

The object is then exported in STL and sliced with Cura

As you can see it’s not fast to print.
Then put it on a paint roll (of course the 3D model must fit your 3D roll)

Then you can use it on a fresh mud plaster: natural, beautiful and with no harm. Of course some try and error are needed, and my long experience with earth plaster helped a lot.

Depending on the texture, you can get nearly seamless results

Don’t forget to clean the roll, but I quite loved it dirty and it gave me idea for the next topic.

And if realy you don’t want environment friendly materials, you cans of course use it on concrete for anti-slippery floors for example:

Wow! That’s wonderful idea!

really beautiful result.nice technique.


Cool and very refreshing idea :slight_smile:

Thanks for the comments.
The dirty roll gave me an idea by the way: to use it to set the transparancy of some transparent printed objects: I fill it with mud, then clean it but leave some clay in the holes. I realy like the way the light plays with it:
