Things I Found Interesting in October 2026

Instead of 3d printing a model completely smooth, come back and add patterned textures to the surface. I was exploring creating a model in freecad, and then exporting it to blender to add a displacement map, then exporting something I could 3d print.

The general process is:

• export obj from freecad
• import obj from blender
• select the faces you want to have the texture and add them to a vertex group
• subdivide that surface a few times if it doesn't have a lot of geometry
• u smart uv unwrap the object
• add subdivision surface modifier
• add displace modifier with a new texture, select uv for coordinates, and the vertex group you created
• adjust the strength
