I'm guessing "too many triangles".  How many triangles does it have?  Or how big is the file size?  There are 2 formats for STL files - one is about 50 bytes per triangle and the other is about 175 bytes per triangle.  Anyway I would say 100MB is probably about the limit for a file size for an STL.  Any larger than that and you probably have features too small to print.


Here's one trick to reduce the triangles: http://www.shapeways.com/tutorials/polygon_reduction_with_meshlab
