3D printing long ago moved from being theoretical to a reality, and in recent years 3D printers have become cheaper to produce; several models are now available for sale, as well as designs for products. Experts predict 3D printers will be common in homes in coming years. Our news and feature articles cover the science and technology behind 3D printers, from how they work to the history, progress and future of the technology and what kinds of things can be made. 3D printing’s uses range from practical objects for everyday use to commercial products and parts used in manufacturing, plus the technology holds promise for bioprinting of human parts for medical purposes.
Gone are the days when building a house required months of hammering wall studs, screwing floor joists and other backbreaking tasks. If a company in China has its way, a new house can be yours in a matter of hours with a 3D printer.
Up until now, most of the popular 3D printing hype has swirled around plastic 3D printers, which have been used to make everything from clothing to art. Now, scientists have built a new open-source 3D metal printer that costs under $1200, and shared their
Researchers at CSIRO, the Australian science agency, have created hot-pink horseshoes that are custom made for each of a horse's four hooves using lightweight titanium and 3D printing technology.
