Context is advanced productive nanosystems.

Explanatory introduction
There is plenty of room at the bottom.
This is the title of a famous speech by physicist Richard Feynman.
This very much holds from the macroscale perspective.
In certain contexts though this turns around into:
"There is limited space at the bottom".
Specifically cramming in enough nanomachinery in a certain amount of
nanoscale volume under the constraint of atomic granularity.
But why would one want to tho that?
The challenge especially arises when it comes to reaching sufficient and
further optimizing for high throughput and low friction losses in productive nanosystems.
Given throughput is determined by temporal density (frequency) times spacial density, and
temporal density is limited due to quadratically growing friction losses with speed (Friction in gem-gum technology),
What one will desires is to maximize spacial density. That is: One will want to use as little volume as possible for
each active site where piezomechanosynthesis is performed.
Put differently: One can put only a certain number of Mechanosynthesis cores (with
single active piezomechanosynthesis site) into a given volume due to atomic granularity.
So the question is: How to get more active piezomechanosynthesis sites into the same amount of given volume?
The answer is specialized mass production of standard parts using molecular mill assembly lines.
See: Bottom scale assembly lines in gem-gum factories'
Instead of general purpose freely programmable robotics
very simple rugged one-task-only robots are uses that have their capabilities hard coded.
But we still want reusability and part recyclability.
This is why we'll call the concept semi hard-coded not just hard coded.
Definition
For semi hard-coded nano-assemblies to be very compact yet still batch-process recomposable the idea is to take an approach with simple blocks.
Imagine having an empty cuboid box that can be filled with various other cuboid blocks
all held together by Van der Waals force.
Side-note: Box being potentially modular too but more sturdy with form-closure-interlock, pre-tensioning, and such. Beside the point here.
Some blocks are …
- … merely for composable spacing of other blocks (like gauge blocks with a set of lengths) … or for same thing but angularly (wedges)
- … for holding functional parts that are necessary within a molecular mill within an piezomechanosynthesis assembly line (mill wheels, track segments, …).
- … for holding composable standard cam-follower system units for guiding mechanisms among highly optimized tool-paths for standard piezomechanosynthesis reactions.
Bulky and space filling design ensures structures are stiffly and sturdily one factor to keep error rates in piezomechanosynthesis low (beside cooling).
So the possible types of parts for "semi hard-coded" structures are include:
- gauge block like crystolecules as composable spacing wedges
- modular parts for cam-followers systems (rotative and linear)
- blocks holding functional units
Scale transposed prototyping
See related page: Applicability of macro 3D printing for nanomachine prototyping
Difficulties here are the absence of Van der Waals force at the macroscale.
Magnets can be used to cheat to a degree.
Also unlike second assembly level at the first assembly level
there is piezomechanosynthesis assembling crystolecules atom by atom as the assembly process
which has no real macroscale analogy.
Rather part pre-production uses 3D printing or casting or some other manufacturing method.
