3D Crystal Jigsaw Puzzles

 

Many of crystal structures are visualized by unit cell representations noting the lattice sites denoted by spheres. However, we think the sphere unit cell model may not be enough to describe the important characteristics of crystal structures. Rather, crystal structures represented by Wigner-Seitz cells, representing net domains of lattice sites, can be very helpful to understand interesting features. We prepared various 3D crystal jigsaw puzzles made of Wigner-Seitz cell polyhedra and base frames. The library of printable 3D jigsaw crystal structure puzzles is expanding. Please visit our webpage frequently to check new 3D jigsaw puzzles. You can download and use the STL files to prepare crystal puzzles for learning, teaching, and fun.
