Take 7 tools. The off-shelf price is listed, and the materials cost for OSE is listed second.
| CNC Torch Table for cutting steel parts | ||
| 150 Ton Ironworker machine for rapid shearing and hole punching of 1" thick metal | ||
| CNC Mill | ||
| CNC Lathe | ||
| Heavy Duty Drill Press (2" hole drilling capacity) | ||
| 200 Amp MIG Welder | ||
| Acetylene Torch | ||
| Total cost: | $77,400 off-shelf + maintenance costs of the same about every 10 years; for a lifetime (20 yr) enterprise, the cost doubles | $11,600 OSE cost + lifetime service, as people can maintain their own machines. |
This would allow one to build all the above tools (self-replication), plus things like tractors, microtractors (lawnmowers), pelletizers to have people harvest their own fuel for mowing from grass clippings; cars; engines, hydraulic motors, and other things from open plans, using CNC assist, and predicted value of labor captured at $100 per hour, or a total ROI of $16k/person/month with 8 hour shifts in a 1000 sq foot workshop.
Make a 4000 square foot workshop to accommodate 4 people, and you have $64k/month earning capacity with 4 people. The question is, can you market $64k/month of machinery?
Needs development of full product release plans for all devices, otherwise, it's doable today.
The entire package allows you to start with raw metal, do metal working and precision CNC, automated machining to yield all electromechanical devices for humankind starting with steel, and making your own components such as engines and hydraulic motors (for flexibility).
Materials:
- Metal and wood are mentioned.
- I don't know where this fits in: http://www.designboom.com/weblog/cat/8/view/12348/kulla-design-studio-50-sawdust.html I can imagine a reprap printing molds, not chairs. Litter as treasure, even.
