Additive manufacturing or 3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes. 3D printing is considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes).
A materials printer usually performs 3D printing processes using digital technology. Since the start of the twenty-first century there has been a large growth in the sales of these machines, and their price has dropped substantially.
The technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many other fields.
Researchers have discovered that a naturally-occurring compound can be incorporated into three-dimensional (3-D) printing processes to create medical implants out of non-toxic polymers. The compound is riboflavin, which is better known as vitamin B2.
3D printing is getting ready to revolutionise space travel. ESA is paving the way for 3D-printed metals to build high-quality, intricate shapes with massive cost savings.
Making stuff on a 3D printer uses less energy—and therefore releases less carbon dioxide—than producing it en masse in a factory and shipping it to a warehouse.
The world’s first 3D printed human-scale structure seen here was designed and created by architects Michael Hansmeyer and Benjamin Dillenburger out of plain sand.
Three-dimensional printers – once available to a small circle of high-tech firms and professionals – are now available to the general public. The ability to produce a prototype quickly and with minimal investment is a boon for the creative sector.
The largest 3-D printed rocket engine component NASA ever has tested blazed to life Aug. 22 during an engine firing that generated a record 20,000 pounds of thrust.
Engineers know that 3-D printed rocket parts have the potential to save NASA and industry money and to open up new affordable design possibilities for rockets and spacecraft.
This space technology demonstration may lead to more efficient manufacturing of rocket engines, saving American companies time and money.
Researchers reveal a new technique to produce high strength metallic alloys, at a lower cost using less energy
Nature inspires creativity: in building a silent propulsion system for boats and water sport devices, researchers used the octopus as their role model. The system can be produced at a low cost and in a single step with a 3D printer.
Talking only about 3D printers and guns is like watching a movie in fast forward, slowing down only to watch the bits where people die.
The first 3D printer bound for space passed a series of critical microgravity tests at NASA's Johnson Space Center in Houston, Texas. Made in Space, the space manufacturing company, conducted examinations of their proprietary 3D printer technology during four microgravity flights lasting two hours e...
