The maker community is embracing affordable mini-mills designed to machine wood and metal.
MakerBot's 3-D printers will soon be able to produce items that look like bronze, limestone, and wood, thanks to a new line of plastic-based composite materials shipping later this year. But the launch may be too little, too late: Entrepreneurs and artists interested in working with metal and wood are already embracing desktop milling machines that can handle the real deal.
