Dependency removed: Supply chain availability for replacement parts and manufacturer repair services - you can produce and repair components locally.
When supply chains are disrupted and replacement parts are unavailable, the ability to fabricate and repair becomes a resilience multiplier. 3D printing, CNC, and basic electronics skills allow a community to extend the lifespan of existing equipment and produce functional replacements for common failure points.
- 3D printing - FDM and resin printing for mechanical parts, enclosures, and fixtures; material selection (PLA for prototypes, PETG/ABS for functional parts); printer maintenance and calibration
- CNC - computer-controlled routing and milling; cutting replacement panels, brackets, and mechanical components from sheet material
- Laser cutting - precise cutting and engraving for acrylic, wood, and thin metal; enclosures, gaskets, and labels
- Electronics fabrication - PCB design and small-batch production; through-hole assembly for repair work; component sourcing strategies
- Plastic recycling - shredding and extruding waste plastic into 3D printing filament; material properties and quality control
- Component harvesting - desoldering functional components from broken circuit boards; testing and cataloguing salvaged parts
- E-waste recovery - identifying valuable components in discarded electronics; safe handling of hazardous materials
- Filament production - Precious Plastic-style workflows for community filament production from recycled plastic
- Local Parts Production - a 3D printer and filament stock capable of producing common replacement parts for networking and computing hardware
- Community Repair Workshop - tools, test equipment, and documented repair procedures for community hardware maintenance
