Marusenko Sphere

The new Marusenko Sphere is both a 3D logic puzzle and an educational toy. It is available in 10 color schemes and five levels of difficulty, depending on the configuration and color combination of its 32 exterior pieces, which are supported by 22 internal elements. The puzzle is solved using nine different types of movements: two meridional and perpendicular to each other, one equatorial, and six polar. Rapid prototyping from plastic powder in an EOS Formiga P 100 additive manufacturing machine played an important role in making the toy a reality. When the design phase of the sphere in CAD was complete, electronic simulation had to give way to testing of a physical model.
