Part Description and Specifications for
"3D Web of Figure8-Knots"
Mutually interlocking figure-8 knots with lobes in tetrahedral directions.
Origin
This was inspired by earlier work on tiling space with knot-tiles.
But here I wanted to make all the knots interlock with one another.
Usage
This part will serve as a geometrical test model
for various fabrication processes and
for efficient representations of the geometry of such irregular
free-form parts.
This experiment is part of a research program sponsored by NSF
to streamline the process of rapid prototyping of free form parts,
by defining a clean interface between designers and fabricators.
Fabrication Hints
The scale or strength of this model is not critical;
it can be scaled so as to fit optimally a particular process
or some remaining space in a run of a larger piece.
This part should be built with SLS or with some other technology
where the support structure can be easily removed.
