Help printing auto-generated terrain

Dear Community,

I am Roberto, from the Software Institute of the Università della Svizzera italiana, in Lugano, Switzerland.

I have been using an ORIGINAL PRUSA I3 MK3 for a side project and I am really happy with that.
However, I often end up having problems in slicing some 3D models. I have tried to repair the models with online tools such as http://makeprintable.com . Sometimes this does the trick, but sometimes it still not working.

I attach a .zip file containing:
- A screencast of the problem (recorded with PrusaControl, same problem with Slic3r PE, though);
- The ASCII .stl model I am trying to print

P.s. I am new to 3D modeling and printing, so any help or suggestion from your side would be appreciated.

Best,
Roberto

Re: Help printing auto-generated terrain

I am not an expert in these sorts of mappings, but a quick look at the STL appears to show only the top (map) surface, not any sort of underlying layers, thus making it impossible to print. Does the tool that you used to create the data offer any options for creating a minimal 1st layer height? The example I tried (see attached STL) allows specifying minimal depth, vertical scaling etc.

Hi bobstro,

Thanks for your reply. I generate the .stl model programmatically from a Scala application I wrote, i.e., no idea on how to create a minimal 1st layer height 🙁

There are some online projects doing these sorts of mappings. Some may be open source. Take a look at those for some ideas. You basically need to generate some filler below the ground surface and the print bed. You've got the hard part done! I'm not sure if MeshMixer or other tools can help.
