|3D Printing: Processes II
Additive manufacturing, which refers to a process by which a three-dimensional component is built using digital design data. The process builds up the object additively by depositing material, one layer at a time. This material deposition can be achieved by employing a wide range of processes ranging from the original photopolymerization technique called stereolithography, to material extrusion and powder fusion using lasers and other high energy beams. In this newsletter, we take an in-depth look at the different processes that are allowing the printing of virtually any material, ranging from plastics to metals and even human cells. These new processes have allowed the cost of additive manufacturing or 3D printing , to drop by an order of magnitude. The technology is poised for explosive growth in the next decade, as 3D printers become widely available and attractive for consumer use.
