This is a tetra-pod made mainly out of carbon atoms in tetrahedral sp3-hybridization. That means the part has the same symmetry as the atoms it is made of.
The surfaces are passivated (plugged) mainly with Hydrogen (white).
to make the surfaces chemically unreactive.
Some sorts of productive nano-systems like nano-factories will be needed to produce / "print" objects like this.
The abbreviation DMSE stands for:
-- Diamondoid Molecular Structural Element
which translates to:
-- very stiff and crystalline -- very small -- non active non moving -- building block
This acronym is rather unsuitable for use in natural language so I'd like to advertise the portmanteau: "crystolecule" for building blocks of this kind. It seems fitting since they are small like molecules but their interior has a dense three-dimensional polycyclically meshed and ordered structure like a crystal.
This structural crystolecule is meant to be used in bigger frameworks like nano-housings etc. The strut ends are unsaturated Surface-Interfaces.
The seven open bonds can be put together in two different ways.
Thus when assembling the tetrapods beside "normal" diamond structure also lonsdaleit structure & many more are possible.
You can find more technical information about
mechanosynthesis and atomically precise manufacturing in general on my website:
or in the book "Nanosystems" written by Eric Drexler.

Marco Tarini, Paolo Cignoni, Claudio Montani: Ambient Occlusion and Edge Cueing for Enhancing Real Time Molecular Visualization, IEEE Transactions on Visualization and Computer Graphics, Volume 12, Issue 5, Pages 1237-1244, 2006, ISSN: 1077-2626
Somewhat related to this is one of the simplest possible structurally usable 2D fractals: http://www.thingiverse.com/thing:14023 .
Extruded this would form some spongy hexagonal tube structure.
To create & convert such models for 3D printing:
) Nanoengineer-1 (http://www.nanoengineer-1.com/content/)
) Blender(2.49b!!) & Plugin:
) Create something in Nanoengineer-1 &export it as .pdb
Load the pdb2blend script directly from the creators site
Credit goes to Malte Reimold!
Use the version that I've slightly modified (included below)
-) brighter atom colors - suitable for 3d printing
-) changed atom radii a bit
-) rectified the double-tabs to single-tabs on line 633 & line 700
[ still not working for newer blender versions :( ]
OR edit it yourself
) Right click on "pdb2blend12.blend" and click on "open with" -> "blender.app (2.49b)" (mac)
) Right click on python script -> choose "Execute Script" from the context-menue
For maximal succesrate use following settings:
Atom Scale: 2.04
Atom Sum: 0
Atom Refinement: 10 (!!)
Stick thickness: 0 (irrelevant)
Stick refinement: 4 (irrelevant)
Low atom refinement means low probability of collinear model edges (baaaad in .stl's)
A hunk of unshaded Atoms will appear.
) right click on the hunk
) Select all: Apple+A (possibly twice, why?)
) Join Atoms: Ctrl+J
) export as .wrl / .x3d / .stl
*) print with printing service in color or on home printer in monochrome
It would be great to remove the useless internal structures without loosing the color information.
Does someone know how to do this?
