Part Description and Specifications for
"3D Hilbert Pipes"


compressed FILE ==> hilbert64.stl.gz                compressed FILE ==> hilbert512.stl.gz
 

Two different levels of recursion of a 3D analogon to the famous 2D space-filling Hilbert curve. These versions are special in that they have no consecutive collinear segments. The two objets will serve as a mathematical demonstration objects and will be the focus of a talk at the BRIDGES'99 Conference.

This design and fabrication effort is part of a research program sponsored by NSF to streamline the process of rapid prototyping of free form parts, by defining a clean separation and interface between designers and fabricators.


Fabrication Hints

These pieces each fit into 3 inches cubes.

Orientation of layered fabrication is uncritical.

In the .STL file describing this part, the vertices from different segments (tori, cylinder) have not been merged. Thus this requires software that does not get upset when when shared vertices appear separated by one unit in the last digit due to rounding errors.
The files come in different resolutions: the large files are about 30Mb uncompressed, the small ones are only about 2Mb.
