Rack Robotics
Maker-accessible industrial machine tools — radically cheaper EDM for American shops.
The product
Rack Robotics builds the Powercore, a self-contained wire-EDM power supply that converts any 3D printer or CNC into a working EDM machine, plus other low-cost industrial machine-tool kits.
The thesis
EDM and other high-precision machine tools have historically required six-figure capex, locking small American shops out of advanced manufacturing. Rack drops the price by 1-2 orders of magnitude.
How it runs
Develops open-source desktop and micro-scale EDM tools, centered on Powercore power supplies and Betta Wire machine designs, with electronics, firmware, CAD and documentation published through its GitHub organization; initial Powercore manufacturing was crowdfunded on Kickstarter.
How it earns
Direct sales of EDM hardware and kits through its online store—including Powercore power supplies, Betta Wire and starter kits, Wire Tool conversion kits, and consumable wire refills—supplemented initially by Kickstarter pledges that funded Powercore manufacturing.
Why it wins
Open-source, configurable electronics and firmware bring precision EDM to desktop-scale machines and allow customization for research, development and specialized implementations.
