ABSTRACT
The Pyr8hedron is a pyramid-like polyhedron with 8 faces, which is based
on the truncated tetrahedron. It has 4 identical regular hexagonal faces
and 4 identical equilateral triangle faces.
In the construction game, only one module will be used. The module is
able to stand alone, but to increase stability, connectors are placed on the
surface. In order to work better with the robot, the connecters are desi-
gned with “slide-in” feature to put the module in the right place.
An ideal fabrication process is to cut the basic geometry in form with
the CNC hot wire cutter, 3D-print the connectors and install them on the
basic geometry with robot. By this time, sample models are made by fol-
ding, completely 3D printing and robotic hotwire cutting. Next phase, 2.5D
printing and folding would also be an option, as in this case it would save
huge amount of materials.
