NeptunLab/KIT Intricate glass creations such as miniature castles and tiny pretzels can now be fabricated using 3D printing, according to a new study. The technique could one day be used to manufacture lenses for smartphone cameras as well as other key glass components, researchers said. Archaeological research suggests humans have employed glassmaking for millennia. The process typically requires hot furnaces and harsh chemicals. Recently, scientists have investigated whether they could sidestep these drawbacks using 3D printing. A 3D printer is a machine that creates items from a wide variety of materials: plastic, ceramic, metal and even more unusual ingredients, such as living cells. These devices work by depositing layers of material, just as ordinary printers lay down ink, except 3D printers can also deposit flat layers on top of each other to build objects in three dimensions.
