Calabi-Yau

thingiverse

The Calabi-Yau manifold, popular in superstring theory (http://en.wikipedia.org/wiki/Calabi-Yau_manifold), was originally created with Mathematica™ by professor Oliver Knill from Harvard University (http://www.math.harvard.edu/~knill/). It is published here with his permission, despite some issues in the STL file. The model can be printed successfully in ABS using a Makerbot Replicator Dual (see photos), and in PLA with an Ultimaker (view the photo of white and pale blue objects). Printing should always include full support and raft, making it a great gift for theoretical/string physicists.
