3D printed guns
While potentially placing guns in the unlicensed hands of the general public isn't the safest option, the development of weaponry using 3D printed parts is still innovative.
While Defense Distributed was the first to develop and release blueprints for 3D-printed parts focused on guns, a 3D-printed gun was later discovered on AR-15.com, showing the construction of a gun using the technology which successfully fired off 200 rounds without signs of complications.
The gun in question combined the normal body of a .22 caliber pistol with a printed lower receiver used in AR-15 assault rifles.
While innovative and potentially useful in the military, if everyone can print off their own guns, there's little point in gun control regulation.

3D printed houses
3D printing is not only limited to healthcare, vehicles, or weaponry — it may also one day provide us with cheaper homes.
An Amsterdam-based architecture firm, Dus Architects, is working hard on a project underway in the country: the construction of a traditional canal house manufactured by 3D printing.
Rather than being built from wood or brick, the canal house is being printed on-site, where Logo-like plastic blocks provide the structure. Each room is printed separately before being assembled to connected floors and stacked to create the house.
The "3D Print Canal House" is a proof-of-concept research project that aims to show how the construction industry can move towards a more sustainable, cost-effective model.

Rebuilding human faces
Cardiff resident Stephen Power had his life turned upside down after a motorbike accident caused grievous injuries to his face.
However, thanks to 3D printing in surgery, his face was reconstructed.
Power shattered his nose, cheekbones, top jaw and fractured his skull through the accident, which left him in hospital for four months.
In an eight-hour procedure the patient describes as "life changing," surgeons at Morriston Hospital, Swansea printed guides, plates, and implants to repair injuries caused by the impact months after being inflicted. CT scans were used to create and print a symmetrical model of Power's head, before printing implants to match. The technology proved to be a success as it took the guesswork out of reconstructive surgical procedures.
