This is a time lapse of a 3D print of the Fractal Pyramid. Details of the printer and filament used are at the end of the video.

Background:
The Sierpiński triangle (sometimes spelled Sierpinski), also called the Sierpiński gasket or Sierpiński sieve, is a fractal attractive fixed set with the overall shape of an equilateral triangle, subdivided recursively into smaller equilateral triangles.

The Sierpinski tetrahedron or tetrix (often called a Fractal Pyramid) is the three-dimensional analogue of the Sierpiński triangle, formed by repeatedly shrinking a regular tetrahedron to one half its original height, putting together four copies of this tetrahedron with corners touching, and then repeating the process.
