Guns are expensive, but if you feel that you need one for self-defense, 3D printing a gun is possible. With regards to the legalities of 3D printing a gun, the Gun Control Act of 1968 mandated that anyone who engaged in the business of dealing firearms must be licensed by the federal government. In addition, firearm dealers must perform a background check for their prospective buyers and maintain records for all sales. 

The act does not prohibit any individual from making a gun for personal use. A non-licensed person may make a firearm, provided that it is not for sale and that he is not prohibited from possessing one (felon convicts). On the other hand, Federal law imposes no restrictions on non-licensed possessors. Thus, if you 3D print a gun, you do not need to register it or go through a background check.

#50 Buildings

BuildingsYes, 3D printers can also make buildings. A Chinese company constructed two buildings with the use of 3D printer. They used recycled industrial waste for their material.

One was a 1100-square-meter villa and the other a six-story residential block. It might not sound appealing to live in, but the Chinese company said that the buildings were safe to occupy.

#51 Car

CarThe first 3D printed car, Urbee was created in 2011. Local Motors is also making their own. In fact, they are developing a 3D-printed car that exceeds the FMVSS standards by 2017.
