Triakis Tetrahedron

thingiverse

This Optimized Triakis Tetrahedron Model is designed for printing on SLA/resin machines like the Form2. It's extremely delicate and pushes the limits of what can be printed on a resin printer, requiring steady hands to remove support material without breaking the model. For a sturdier version, simply scale up to a larger size before printing. To print on an FDM/filament printer like an Ultimaker, double the size of the resin model or download our previous thicker version. Fun Facts about the Triakis Tetrahedron: - It has 12 faces, 18 edges, and 8 vertices - Each face is a unique isosceles triangle - One of the 13 Catalan solids - Dual of the Truncated Tetrahedron - It's a tetrahedron with triangular pyramids added to each face To download more polyhedra like this, visit our Catalan Polyhedra Collection.
