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).
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)

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