3D printing. An ORDbot Quantum 3D printer. 3D printing or additive manufacturing[1] 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.[2] 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes).
A 3D printer is a limited type of industrial robot that is capable of carrying out an additive process under computer control. The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields.

101 Gadgets That Changed The World - Top 101 Gadgets of All Time. 74.
Safety Razor King Camp Gillette did not invent the safety razor--that honor goes to the Kampfe Brothers, circa 1880--but his company, founded in 1901, quickly became the foremost name in facial hair removal. Advanced manufacturing methods, low prices and shrewd promotion--for example, Gillette arranged to have his safety razors issued to every American soldier during World War I--changed the practice of shaving from the exclusive domain of skilled barbers to an everyday act that any man could perform from the comfort of his own bathroom.
And according to Gillette, his blade saved money and time, too. How do solar panels work? Solar panels collect solar radiation from the sun and actively convert that energy to electricity.
Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode.
