• be exported to .STL format, one model per file
  • We will not print any STLs that contain more than one model
• be less than 14"x10"x14", scaled in inches
• pass the Shapeways tests for "White Processed Versatile Plastic" (3D Tools)
  • You must provide a screenshot of the test results (contains checkmarks and render of your model) for each file
    • If you change your file in any way after you run through Shapeways, you need to run it through again
    • If your file is too large for Shapeways, use the reduce mesh command in Rhino: ReduceMesh command
  • We will not print any files without an associated screenshot
• have no naked edges
  • We will not print any files containing naked edges
• have a minimum feature thickness of 1/16". 
  • We will not print any files containing feature thickness under 1/16"
  • 1/16" is the minimum for simple and rectilinear geometries
  • More complex geometries (such as curves) should be thicker to avoid printing issues
    • Even if your model passes Shapeways with no warnings, your print may break if complex features are 1/16"

1. Create a free account at Shapeways and click the "Upload" button to test your .STL file

   1. After uploading, go to "My Models"

      1. Click on the "..." and then "Open in 3D Tools"

         1. 

      2. Note that this can take anywhere from a few seconds to many hours to process

         1. If your file is too large for Shapeways, use the reduce mesh command in Rhino: ReduceMesh command

      3. The model must receive all green checks mark for "White Natural Versatile Plastic"

      4. The photo below shows an example of the quality check results on Shapeways–this model didn't pass all of the required tests
