Resolves when a printed printer manufactures a working printer. This is similar to the Reprap project, but must use only printed circuitry.
Details:
Human assembly of printed components is acceptable
Can involve multiple printed machines in the same location, so long as the set of machines can duplicate itself
Raw material inputs like these are acceptable:
ABS or similar plastic filament
Various metals & powders
Insulated copper or fiber optic wire bought in bulk
Other unspecialized components of similarly low price
Moderate degradation of performance or reliability in the output copy is acceptable if the system is still somewhat usable.
These must basically be 3D printers, ie: it must be possible to use these printers to make other similar output items, using materials like metal & plastic.
Spirit of the question:
When can a person run a 'printer farm'?
When can they use their printer inventory to make more printers?
When is this technology first demonstrated?
These printers will be roughly the same size, material composition, & degree of complexity as modern 3D printers.
@ConnorDolan Ha, i see what you're saying. I should edit the description to exclude living organisms from this.
