The diamondoid atomically precise manufacturing and technology (DAPMAT) demo project collection. A collection of projects conducted by Lukas M. Süss (aka mechadense).

The collection is an attempt to raise awareness of the possibilities and challenges arising from the upcoming revolution with advanced atomically precise manufacturing.

It is meant for the creation of a collection of 3D printable models that:

• Demonstrate functional parts that are likely to be useful in advanced diamondoid nanofactories.
• Illustrate principles that are of importance 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

library for cycloidical gears

Screw library allowing soft tooth profiles approximating atomic scale crystolecule screws

• Work in progress ...

Screw library demo output

(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
• single big truncated octahedron model (by ?)

Shape locking

Stiff rods

• http://www.thingiverse.com/thing:200203

In plane flexible chains

• (two example types): http://www.thingiverse.com/thing:591203

Reinforcement core chain and spanners

• work in process

Infinitesimal bearing

• old and new model - work in progress (TODO: improve and publish 3D-model)
• (TODO: present purely rolling nonsliding concept too)
  

• animated demonstration of principle

view full sized to see animation

Constant velocity joints

• Tracta joint (compact and sliding thus very suitable for superlubricating crystolecules) ... work in progress

Complete set of passive elements for mechanical circuits sub-projects

Mechanical distribution node

A 1:1:1:1:... differential gear assembly this is essentially the mechanical equivalent of a trivial electrical solder junction (TODO: improve and publish)

Spring (as analogy to electrical capacitor)

• (TODO: Upload screenshot for now)

Flywheel (as analogy to electrical inductor)

• (TODO: make a model)

Demonstrations of principles

Convergent assembly visualizations

• two iterations fourfould multiplier with elongated bottom: http://www.thingiverse.com/thing:582270

(TODO: more realistic with only a single bigger step visible)

Vacuum management

• progressing cavity pump (TODO: publish)

Fractal metamaterial redundancy principle

• How metamaterials can create reduncancy
