The DAPMAT demo project

The diamondoid atomically precise manufacturing and technology (DAPMAT) demo project collection.

A collection of projects conducted by Lukas M. Süss (aka mechadense) for the creation of a collection of 3D printable models that illustrate functional parts in advanced diamondoid nanofactories.

(TODO: add a picture of the whole printed collection)

Libraries

Those are also very helpful for everyday macroscale 3D printing projects.

Cycloidical gears as rough approximation for atomic gears

• on github: https://github.com/lsuess/scad-lib-cyclogearprofiles
• on thingiverse: http://www.thingiverse.com/thing:777936

Screw library allowing soft tooth profiles approximating atomic scale crystolecule screws

• In the works ...

(TODO: finish and publish - for now upload screenshot)

Models which are useful in macroscale too

Microcomponent models

• truncated octahedra assembled into the main planes: http://www.thingiverse.com/thing:409443

Spring (as analogy to electrical capacitor)

• (TODO: Upload screenshot for now)

Flywheel (as analogy to electrical inductor)

• (TODO: make a model)

Demonstrations of principles
