government is the least productive—the federal government is the least productive of our economic sectors. The most productive is the private sector. The next most productive is the not-for-profit sector, then comes state and local governments, and finally the federal government. And so moving responsibilities from the federal government to the states or to the private sector will increase productivity.
Don’t forget! It’s the private sector jobs that pay for government workers. So if you have fewer government workers doing work more and more productively, that means private sector work will grow.
While traditional paper printers use a moving toner cartridge head to form lines of text, adding row upon row of toner as the paper moves through the printer, 3D printing works much the same way. Instead of toner, however, a free-moving printer head precisely deposits layer upon layer of plastic or other material to create a solid object from the bottom up.
the time to market is compressed immensely. The other key aspect is that the risk of going to market is almost non-existent, because your investment is only the design of the product itself
3D printing allows you to make incredibly complex designs at no additional cost: interlocking components, naturally hinged parts, semi-translucent surfaces, and even objects that can move on their own without assembly
