WWR Article Summary (tl;dr) Although 3-D printers and milling machines work differently, they represent the same basic philosophy that entrepreneur Bre Pettis and others in the maker movement espouse: giving everyone tools to be creative.

Entrepreneur Bre Pettis sparked an unfinished revolution in 3-D printing.

Now he has purchased a Berkeley company that wants to make the manufacturing of everything from fine jewelry to precision electronic parts just as accessible to the masses as desktop publishing.

Last month, Pettis bought Other Machine Co., which makes a portable milling machine for electrical and mechanical design engineers and educators who want to quickly create prototypes.

Other Machine co-founder and CEO Danielle Applestone believes her company’s machine could represent a future of manufacturing — reliant more on the innovation of individuals and less on giant factories.

“If the means of production are inexpensive and easy enough for anyone to use, more people will produce things,” she said.

“We’ll have a lot of really small factories,” she said. “I see that as more economically robust, because you don’t have to bail them out. If one fails, then another one starts and it’s not that big of a deal. But that hasn’t happened, mostly because the tools are so expensive and you had to be trained on them.”

The company’s product, the $3,199 Othermill Pro, is a 17-pound, computer numerical controlled milling machine capable of creating parts out of a variety of materials. Unlike a 3-D printer, which adds layers of material to create a product, this machine subtracts parts of the material.

To demonstrate the Othermill Pro, which is less than 1-foot square, an Other Machine worker programmed the computer-controlled blade to etch lines one-6,000th of an inch thick on the surface of a small copper-clad surface that could become part of a computer board.
