The microfactory is a set of tools and machines that can be reasonably acquired or built from abundant materials with the goal of enabling humanity to transcend scarcity and poverty.
A factory has inputs and outputs. The decision of which tools and machines comprise the microfactory is a function of the available inputs and the expected outputs, including the requirement of self-replication.
Inputs
Criteria for selecting inputs for the microfactory:
- abundant: it should be easy to acquire useful amounts of the material for free or at insignificant cost
- safe: acquiring, handling and processing the material should not be inherently dangerous; common mistakes should be reasonably forgiving
- appropriate: see https://en.wikipedia.org/wiki/Appropriate_technology
The following materials have been selected as inputs for the stated criteria:
Wood
- renewable material that is abundant and free if harvested from your own property
- wood has been used by humans for thousands of years and can be safely worked with primitive tools
- many existing methods, tools and knowledge on working this material
Plastic
- PET soda bottles and HDPE milk jugs are everywhere
- used for storing food, is expected to be safe
- it's only in the last decade that this material has become appropriate for a home based microfactory. methods, tools and knowledge is still at early stages
Aluminum
- soda cans are everywhere, aluminum scraps are also abundant
- much lower melting temperature than steel, home made foundries for aluminum are popular
Methods
aluminum forge to melt aluminum cans and other scrap

- https://www.youtube.com/watch?v=XZo5o1Y0h9o
make wire out of ingots
circuit "printer"
- 3d print board with groves for wire and components
- place aluminum wire into grooves: http://reprap.org/wiki/SpoolHead
- apply solder paste
- pick'n'place components
- melt solder in oven
aluminum extruder
- heat billets to 900F
- push through die
- cool consistently
