Since 2011, 3d printing has attracted worldwide attention. It brought this innovative revolution to manufacturing. We never knew we could do this. Before when we needed a component, we could only depend on Fedex. But now we can deliver objects by sending data on computer. All we need to do this is 3D drawing, a 3D printer, one spool of filament! In the past, the time for making a plastic component is: (mold opening: 1 month + re-deployment: 1 month + delivery to supplier: 1 month + delivery from supplier: 1 week)! Now all the time you need is: (some time to download design drawing + several hours to print)! See how 3D printing will shorten the time?
