Naval Sea Systems Looking To Embrace 3D Printing Following Redesigned Bolt Tool

3D printing is the latest innovation in tooling, leading to the creation of 3D printed pressbrake and other tools, as well as a new 3D tie bolt anti-rotation tool for an airplane.

The latter is the latest endeavour made by the United States Naval Sea Systems Command, at the Norfolk Naval Shipyard (NNSY) in Portsmouth, Virginia, which it then used in practical application, followed by an additional 100 orders for distribution throughout the NNSY’s Inside Machine Shop on land, as well as the force’s seafaring vessels.

The NNSY is the field operations of NAVSEA, which is specialized in repairing, overhauling, as well as modernizing the United States’ ships and submarines. It’s the largest, as well as the oldest facility operated by the US Navy, and has been noted for causing and creating many of the Navy’s latest innovations, like the construction of the USS Texas, the country’s first commissioned naval battleship.

The 3D printed bolt tool that they produced was made thanks to a collaboration between the NNSY’s Inside Machine Shop (Shop 72), and the Rapid Prototype Lab.

According to NNSY Lifting and Handling Specialist Jonathan Woodruff, the tool is an update on the yard’s current technology. He says that the department usually used a single tool for tie bolts, which he describes as akin to pliers with metal on the stop to stop the rotation of the bolts.

He says that the tool, while reliable, was tedious to use and was the only tool that the entire shop could use, which is why they decided it was time for a change.

The new tool was initially designed in 2D, before being 3D modelled in CAD, then 3D printed. The tool was tested for use during the design process, modified in order to meet specifications. The final prototype was then 3D printed in impact-resistant polycarbonate plastic, the material used for bullet proof glass and CDs.

Following the creation of the prototype, it was then present to the NNSY Rapid Prototype Lab, where it was tested, where it passed and was approved for use.

The overall cost for 3D printing up to eight tools in a single build ranges at a  mere $30, which is why the NNSY is considering rolling out the 3D printed tool out across the entire NNSY workforce, following the innovations in 3D printed tools and parts, like pressbrake and aircraft components.

Money-Printing Industry In China Sees Surge Due To High Quota From Other Counties

China is printing money for other countries in the hopes of expanding their power in the international economy.

United States, Canada, and NZ sticker printing, poster printing, and book publishing are just some of the few examples of printing services all over the world. While these may be usual services acquired by private citizens, businesses, and even government offices, China is looking at it from another perspective: banknote printing.

Full Steam Ahead

The country’s money-printing plants are running near full capacity to meet the quota from countries such as Poland, Brazil, Malaysia, India, Bangladesh, Thailand, and Sri Lanka.

Chinese yuan bills are still being printed, but it was reported that it only comprised a small percentage of orders, with the majority coming in from foreign countries.

Belt and Road Initiative

Other countries like Canada, US, and NZ sticker printing, and book publication mainly seek to provide services on an as-needed basis, but for China, it is on a much wider scale. The money printing is said to have been linked to their Belt and Road initiative launched in 2013. It seeks to stimulate growth in the economy of around 60 countries across Europe, Asia, and Africa, mainly by providing infrastructure projects and investments.

In 2015, they started printing money for Nepal, but has soon started providing services to Bangladesh, Malaysia, Thailand, Brazil, Sri Lanka, and Poland.

Rise from the Bottom

The project is seen as an improvement in the country’s perception of currency printing as Chinese citizens have recently started to favour mobile and banking services over cash.

 

China Banknote Printing and Mining Corporation, the state-owned company tasked for the job, has employed around 18,000 workers and employees, and built ten plants solely for printing coins and bills. In comparison, the United State’s Bureau of Engraving and Printing has less than 2,000 people.

Trust and Alliances

Beijing Institute of Technology Economics professor Hu Xingdou believes that this is an important step in China’s growing power in the world economics. Printing banknotes take a lot of trust, showing how other countries are slowly starting to see the country as a reliable partner. Currency also symbolizes sovereignty, and having it printed by another country shows the countries’ willingness to cooperate for monetary alliances.
