Myth #1: 3D Printing will never catch on because it is too technical. This technology uses specialized diagrams, complicated drawings, unusual materials, and requires an understanding of engineering, computer aided design (CAD), and computer automation. The 3D printing machines need special parts that are not easily available.
Myth #2: Most people won’t do any 3D printing because they’re not manufacturing people. Let’s face facts. How many people even understand manufacturing? And the USA is a service economy. Most MBAs aren’t studying manufacturing and the USA’s expertise is in marketing. Are we really all going to have desktops and spools of plastic going back and forth on our kitchen counters?
Myth #3: 3D printing will never replace traditional assembly line manufacturing. It’s much more cost-effective to have hundreds of men and women lined up in a room making 1,000 widgets with each production run. Didn’t Henry Ford invent the assembly line because it made more economic sense?
Myth #4: 3D printers are very slow and take a long time to make one product, so who can wait? Why wait 1-4 hours for a plastic syringe to be printed when you can have a cabinet full of them, ready to go?
Myth #5: You can only make plastic junk from 3D printers. Every picture I see of 3D printing shows some plastic cup or ball. Who needs it? How many people are using mosaic spheres in our world?
