Pants-pockets gemstone-gum factory

What it is and what it does
The personal gem gum factory is:

Self replication in the bootstrapping process
Compact self replication is not (!!) a prerequisite for the bootstrapping of advanced nanofactories.
For details about how the bootstrapping process could be performed check out the main article: "Bootstrapping".
Self replication in normal usage
Beside useful products a personal fabricator can quickly produce copies of itself and that without any special raw materials thus you can make copies for all of your friends and they can make copies for all of their friends. Since everyone is linked to every other person on earth through a low number of acquaintanceships Wikipedia: six degrees of separation (well not entirely true) you can imagine how fast this can spread. We know it from software.
Specialization pushes self replicative capabilities into the macroscale
A main defining feature a gem-gum nanofactory (if not one of the most important ones) is that while the whole system is general purpose all its various subsystems are highly specialized. Much like what you find in a general purpose computer. There's no magic computronium inside.
This makes it:
- much more efficient than the old and now obsolete molecular assembler concept
- not possess highly compact self replicative capabilities as the molecular assembler concept
Specialized one-task-only pick and place mechanisms can be smaller and faster than general purpose ones (just as in macroscale factories).
When every standard part needs it's own production line then a system capable of self replication that needs many part types naturally becomes quite big.
Stage step table
You may meander through this table in two ways:
- size wise column by column including all the repeating processing steps (including the assembly levels) and/or
- type wise row by row showing how the chosen aspect of the processing chain changes with scale
The assembly levels are about the size and character of the intermediary convergent assembly steps both the assembly systems (assembly chambers, assembly manipulators, ...) and the general character of the product-fragments assembled inside. The design levels are about product design software that matches these levels.
Assembly levels are mostly static and will likely only change significantly when the nanofactory itself receives an upgrade. The design levels are about software tools for actual concrete product design which may change on every production run (with the exception of hard coded assembly in the initial convergent assembly steps).
|Caracteristics||Level 0||Level I||Level II||Level III (and up)|
|Type of Components|| Molecular fragments
wanted: versatile abundant and nontoxic elements
wanted: standard building blocks (mass produced "nuts and bolts")
wanted: reusable units (possibly indivisible)
| Product fragments |
wanted: composable metamaterials
|Examples for typical Components||Fragments of simple compounds CH4, CO2, ... including at least some basic elements: C,H,Si,Ge,...||
|Comprehensible size comparison model scale 500.000:1||Model atoms have the diameter of an average human hair (0.1mm)||Model crystolecules are from the size of a grain of salt to the size of a playing dice (1mm-16mm)||Model microcomponents are the size of a big plant pot (~50cm)||Model product-fragments are the size of a house (~16m). A 50m wide soccer court scaled down 1:500.000 is visible by eye - it has the width of a human hair.|
|Physical Properties (strength, wear, friction and more)|| atoms are eternally wear free
(for all practical purpouses)
||inheriting toughness||emulated properties via metamaterials|
| Methods for Connection
||advanced auto-align mechanisms|
|Character of Manipulators|| fast mass production/preparation in stiff molecular mills
(employing 3 tip tricks)
|conveyor belt assembly||stiff manipulators with parallel mechanics akin to steward platform||conventional factory robot arms with serial mechanics. Even further up at macroscale: Highly dexterous tentacle robotics. Megascale: sparse cranes.|
|Internal distribution / logistics||Moiety routing: Note: even for basic hydrocarbon handling this is quite complex||Major rail routing station: Note: Redundancy requires fail safe producers and consumers|| Minor rail routing station. For microcomponent recomposition
| No routing. (?) |
Possibly general purpose robotic pick and place.
(Macroscale: Streaming parts through tentacle robotics?)
|Airlocks and clean keeping||All mechanosynthesis happens under practically perfect vacuum. No airlocks at this scale.||Possibly early vacuum lockout of passivated crystolecules.||Main vacuum lockout step. Passivated microcomponents can be assembled and disassembled in air.||Possibly early clean-room lockout. Bigger product fragments can handle dust and dirt - to a degree.|

- Up to a more general concept: Advanced productive nanosystems
- Pants-pockets gemstone-gum factories are both part of and origin of in-vacuum gem-gum technology.
If that sounds paradox it's because of the chicken egg problem of bootstrapping such factories.

some details are different than in the final versions.
