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)

convergent assembly visualisations

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

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

crystolecules

• Drexlers big bearing as printable model http://www.thingiverse.com/thing:631715

• Fractal tetrahedron design: http://www.thingiverse.com/thing:13786

microcomponent models

• truncated octahedra assembled into the main planes: http://www.thingiverse.com/thing:409443
• single big truncated octahedron model (by ?)

vacuum management

• novel lockout mechanism (TODO: publish) -- on flickr: [1] [2] See: "Vacuum handling" for details.
• progressing cavity pump (TODO: publish)

shape locking

• stiff rod: http://www.thingiverse.com/thing:200203
• chains (two example types): http://www.thingiverse.com/thing:591203

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)

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

(TODO: publish 3D-model)

view full sized to see animation

Demonstrations of principles

Fractal metamaterial redundancy principle

• How metamaterials can create reduncancy

(TODO: add image of published 3D-model)

Reversible mechanosynthesis

An illustration of the basic principle for reversible mechanosynthesis.

(TODO: Publish 3D-model)

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)
