In this instructables I will show you how to make a 3D door sign with a realistic mountain panorama as background.
The mountain panorama is created from real world elevation data.
The door sign is then created using a CNC mill

Step 1: Tools and materials

You need:
If your CNC milling machine is not strong enough (as mine):
  • some sort of dense foam
  • some mold making material (I used natural rubber)
  • some pouring mass (I used the ceramics-like pouring mass "ARTIDEE Artestone" )
I've been looking into greyscale image to 3d topography type software as well, it seems like the software you are using might be doing some smoothing on the final stl file? do you think that's right?
Hi, To be honest i've done this project nearly 10 month ago.. so i don't remember everything in exact detail. But I didn't create stl files at all. I went directly from greyscale to gcode.<br>But i think i might have smoothed (gaussian blur) the greyscale prior to generating the 3d model in Blender from it.<br>I've only little knowledge of blender, but it might have done some resampling (and therefore smoothing) during the generation of the model Form the greyscale.<br>In the final image i did some brightness corrections so hat the flowers where not too much elevated and the text was really on top of everything
