THREE-DIMENSIONAL PRINTING-THE TECHNOLOGY COULD BE USED TO MAKE PARTS THAT PERFORM BETTER AND COST LESS The technology for printing three-dimensional objects has existed for decades, but its application has been largely limited to novelty items and specialized cus- tom fabrication, such as making personalized prosthetics. The technology has now improved to the point where these printers can make intricate objects out of durable materials, including ceramics and metals (such as titanium and aluminum), with a resolution on the scale of tens of micrometers.
