3D printing, also know as additive manufacturing, has already made a lot of inroads with designers and in the manufacturing industry. 

But as the printers become less expensive, more powerful, and easier to use, consumers will also increasingly adopt the technology. This will enable them to print things at home on demand. 

Demand for the technology has already grown more than it was expected. In 2014, there were 133,000 3D printers sold worldwide, which is a 68% increase from 2013.
