Self assembly

Important (and maybe non-obvious) fact:
Not all kinds of self assembly need diffusion driven by thermal motion to work.

There is:

• Thermally driven assembly (aka "brownian self assembly")
• Non-thermal selfassembly driven by longer range attraction forces.
  E.g. like how magnets can do self assembly at the macroscale

The foldamer printer concept where:

• Thermally driven assembly may be used to make the base vitamin parts that constitute that most basic building-blocks.
• The foldamer printer then performs some semi positional assembly of these basic building-blocks to larger composite blocks that
  form hinge interlinked chains of blocks.
• Non-thermal selfassembly may then finally self assemble the even bigger products block chains (that would diffuse only very slowly) to even bigger structures in a non thermally driven diffusionless way.
