Thermally driven assembly is also called called self assembly or brownian assembly (seldom)
(TODO: Add minimal definition)

• Today thermally driven assembly is already extensively used (e.g. structural DNA nanotechnology) this will continue onward into the early stages of the development of atomically precise manufacturing (APM).

• In the early and the later stages of APM development: brownian mechanosynthesis could be an intermediate step to advanced APM systems.
• In the later and the final stages of APM development: self assisted assembly will come to intensive use.

Beside the actual function of the building block (structural element / machine element) completely unguided thermally driven assembly requires the building blocks to be have a unambiguous unique puzzle piece shape that completely determines its target position. (everything that can stick will stick)

• Brownian assembly is generally slower then advanced directed assembly like mechanosynthesis. (numbers needed)
• The ambient temperature dictates diffusion speed.
• Lower dimensionality that is diffusion on a surface instead of a volume or on a line instead of a surface speeds up the process.
• Dividing one long diffusion path to several shorter irreversible diffusion transport stretches speeds up the process.
