3-D Printing and Energy Efficiency 0

3d-printing3-D printing, also known by its technical name of “additive manufacturing,” is a concept that makes tech-heads and entrepreneurs bubble with excitement. President Obama even gave 3-D printing a shout-out in his recent State of the Union address, talking about a government-sponsored lab in Ohio for testing and scaling new technologies: “There’s no reason this can’t happen in other towns,” he said.

Indeed, 3-D manufacturing could make any town a hub for the production of goods — or any home for that matter. As costs for 3-D printing technology continue to drop, theoretically, in the near future, anyone could produce toys, car parts, batteries, clothing, and a range of other products the consumer (now the manufacturer!) dreams up.

This could dramatically improve the efficiency of the economy. In an oft-cited study, the Department of Energy estimated that 3-D printing can reduce energy costs by 50 percent and cut material costs by 90 percent. This could also change our definitions of what constitutes the manufacturing sector, the commercial sector and the residential sector. Is a commercial business that is printing and selling medical products now a healthcare manufacturer? Is a guy printing custom car parts out of his garage now an auto manufacturer?
