NASA recently made it possible for a 3D printed spanner to be created aboard the International Space Station. Serving to highlight how far the technology has come, the feat will help propel 3D printing into a development daze. We’ll be seeing controversy, regulation and even more success stories with regards to the industry. Hardware and equipment costs will fall, leading to increased access and applications in industrial, health and commercial areas. Perhaps a 3D printer won’t be a realistic buy for the home in the next year, but 3D printing services will become more widespread and more accessible as regulations are ironed out.
