I am having trouble exporting meshes as .stl files from blender, when I import the exported mesh into Slic3r nothing shows up. However when I import an already existing model into blender and then export that as a .stl, it works fine in Slic3r
You need to triangulate the mesh. Select the mesh you wish to export and add a Triangulate Modifier to it. Then in the .stl export dialogue enable Apply Modifiers.
.stl imported to slic3r
For me to get this to work. I changed units to metric. To create a 2cm cube I had to create a cube and set the scale to 2cm. I made sure that I applied the scale to the cube so that it says:
scale x: 1 scale y: 1 scale z: 1
length: 2cm width: 2cm height: 2cm
Then I exported selected as *.STL and dragged into Slic3r. From there I applied a scale of "100,000" as "100" was default. YES you heard that right 100k. I'm not sure why this happening but it works for me and I measured my model after i printed it and it's 2cm square. Hope this helped.
Be sure to select your model before exporting to STL.
The export turns up empty when no object is selected.
Check the file size for the STL file after export. It should be bigger than 100 bytes or so. My empty file is 84 bytes.
I have been trying this. My model is in blender units, and I had the same problem.
If your blender model is in blender units, you have to scale x 1.000, as one blender unit is a millimeter in slic3r. Try this and tell us if you solved the problem.
