US Navy Uses Three-Dimensional Printing Technology




US Navy and the Oak Ridge National Laboratory recently participated in the first submersible printing using 3D printing technology, which was printed in less than four weeks, using the submersible for the deployment of logistics capabilities and sensors, Optionally Manned Technology Demonstrator, Of the three-dimensional printed vehicle by 2019.

The submersible is a small underwater vehicle designed to operate underwater. It is different from other underwater vehicles known as submarines. The submarine is a fully autonomous vehicle capable of renewing the energy and air needed to breathe. The submersible is often supported by a floating vessel Operating platform or team running from land.

Diverses worldwide are used for many things, such as oceanography, underwater exploration, ocean prospecting, maintenance, repair and imaging. Armed forces around the world use 3D printing to reduce cost and time for future missions, Spare parts for warplanes, grenade launchers or meals for soldiers.

The 3D submersible submersible was developed by a team from the NSWC and the Carderock Technology Lab. Although the idea of ​​printing weapons or vehicles was something of a science fiction, these things became closer to being found and the armies could use This technique over the next two years if everything went well.

The team began working in August 2016 and used a large 3D industrial 3D printer called “Big Area Additive Manufacturing” to manufacture six carbon fiber sections, which were later assembled to form a 30-foot vehicle.

The team spent four weeks developing the structure, the first week spent on the structure design, and the process of printing the components began a week later. The submersible is currently the largest US Navy vehicle printed in 3D. According to the Department of Energy, the traditional cost of the body ranges from 600 to 800 A $, it usually takes between 3 to 5 months to manufacture, while this version was 90 percent cheaper and was produced within a few days.

This submersible is a major deal for the US Navy Corps, because this rapid shift means that specially designed parts or equipment can be quickly manufactured and distributed. Although the printed body is not an integrated device that can be used directly, it is evidence of a concept to identify Whether it is possible to print something that may be useful in the future, the purpose of this process was to find out a faster and cheaper way of working from the manufacturing process using different methods.
