Additive Manufacturing for Warfare 4.0

Recognizing the advances in Additive Fabrication technologies, the United States Marine Corps has set up a dedicated Additive Manufacturing program with the aim of mass-producing militaristic items with ease and at any location.

Looking deeper, it is only right to state that this program—which was heralded by the Logistics Innovation Challenge—was developed to give the US Army a considerable edge during wartime.

The program has recorded considerable successes for it led to the development of an unmanned aerial system named ‘Scout’ with reconnaissance features which was built with approximately $600.

The fourth industrial age is here to stay and the exact roles 3d Printing will play in defining how it develops can only be speculated at for now. But one thing is sure: manufacturing in every industry vertical—bio-medicine, the military, engineering, science etc.—will come to rely heavily on the on-going innovations in the field of Additive Fabrication Technologies.

This revolution would definitely have enhanced the German war effort during the battle of Stalingrad by drastically reducing the logistics associated with carting ammunitions as well as other goods from Germany and its environs to Russia. And it is also definitely going to change modern warfare as we know, it in the coming years.

3D Printed UAVs: Guide, Resources, Materials, and Ideas

¿What is the benefit of 3D printed UAVs? Read about the pros and cons of 3D printed UAVs, plus a guide to the best resources to be found online. Right here, you can jump to the topics directly:

ARL apply Additive Manufacturing to UAV Manufacturing

Additive Manufacturing has become prolific in the military, being used for various applications and across divisions. Now, two of the US military’s branches are teaming up for the development of 3D printed UAVs: “Several years ago when we were collaborating with our academic partner, Georgia Tech Research Institute, we had this project where we were focusing on design engineering of small unmanned aircraft systems,” said Eric Spero, a team lead within the Army Research Laboratory’s (ARL) Vehicle Technology Directorate.

The idea was to enable soldiers to custom design UAVs for specific missions using an app, and then to 3D print them within 24 hours. Spero and his team brought the project to life as part of the Army Expeditionary Warrior Experiment (AEWE), which gives soldiers access to new technologies. Researchers from the ARL then reached out to the Marines, knowing that the Marines had been working with 3D printed UAVs, and began developing a software catalog that would allow users to choose and 3D print an UAV for their specific mission needs: “We have interacted with Marines who have never touched an unmanned system before to Marines who are experts in unmanned aerial flight,” said ARL engineer Larry “LJ” R. Holmes Jr. “Across the board they all seemed to be very interested in the topic of being able to manufacture a tool that they can use that was mission specific and has a turn around.”

The Marines expected that turnaround to be days or weeks, but the ARL showed them that it could be anywhere from minutes to hours. The researchers said they plan to streamline their processes based on feedback from the Marines to optimize situational awareness: “Things like additive manufacturing with materials, artificial intelligence and machine learning, unmanned systems technologies, these will enable us to bring together the capabilities that will allow the future Soldiers and Marines the decisive edge that they need in the battlefield,” said Elias Rigas, a Division Chief in ARL’s Vehicle Technology Directorate.

Aerialtronics and Department of Defense to focus on Additive Manufacturing

Aerialtronics is a Dutch company producing commercial UAVs. Because of its 3D printing capabilities, their UAVs can be fully customized to meet the needs of individual customers. Some UAVs are used in livestock monitoring, infrastructure inspection, and creative filming.

It was estimated that the company’s research and development costs were diminished by 50% from the use of 3D printing3D printing is used to create different-sized sensor equipment, GPS systems, and boxes that accommodate for cables and other electronic components.

Aerialtronics uses Stratasys 3D printing technology to build the UAVs. On a broader scale, streamlining and employing this more cost-effective process permits small companies like Aerialtronics to become a strong contender in the international UAV market.

There is no doubt that 3D printed UAVs will continue to grow into even more useful applications that simplify our lives and meet our everyday needs: Imagine being able to build an UAV on the whim, and customize it to your own specifications, thus making it more affordable and accessible than ever before: This becomes a reality with today’s 3D printing capabilities.

Aside from the benefit of creating custom UAVs, 3D printing offers easy upgradation opportunities: In other words, it is easier to make modifications to a 3D design, then print and test it until the desired variation is achieved. In other ways, now a user can replace broken or malfunctioning parts on an existing UAV with 3D printed ones. So far, several components can be 3D printed including the frame, landing gear, propellers, camera mount, antenna holder, and protective equipment.

Another advantage of 3D printing results from building UAV parts in new lightweight materials. An UAV will perform better and fly longer when it is lighter. It also has better battery life and responsiveness to commands in-flight when it is lighter and weight is evenly distributed. The versatility of materials used for 3D printing translates into higher performance features in the UAVs.

Military branches are also focusing on 3D Printing to explore new ways to make cheaper, lighter, and more effective UAVs. A Marine Corp named Rhet McNeal created Scout, an UAV composed of 3D printed components. This UAV only costs $600 to build in comparison to a traditional one that costs hundreds of thousands of dollars. Since it is 3D printed, should the UAV receive any damage, the parts can be easily printed and replaced within hours. On the other hand, a standard-issue UAV would require weeks, sometimes months, to get a replacement through the Marine Corps’ supply line. Scout is now in the hands of Mitre Corp., a USMC UAV supplier, to undergo certification testing.

¿More examples? The University of Virginia created a 3D printed UAV for the Department of Defense that can be printed in less than a day at $2,500, including electronics development. The body of the drone only costs $800. It is known as the Razor since it appears like one long wing. Weighing in at 6 pounds with all the equipment, the Razor can fly at 40 mph for up to 45 minutes.

The features and capabilities of the Razor are not compromised by the fact that it is 3D printed: after all, it has all the same functions as a traditional UAV with GPS waypoints for navigation, mile-distance control, camera hoisting, and phone linking capabilities that extend the distance it can be controlled within. The greatest advantage of this being 3D printed is that it can be modified and reprinted on the whim.

Last but not least: Soleon is an Italian UAV company advancing its efforts in 3D printing UAVs. Because it deals with diverse projects, including aerial photography and thermal mapping, designs ought to be flexible and quick for upgrades. Soleon uses Materialise to meet customer needs, shorten lead times, and reduce UAV weight. One of their 3D printed UAVs is called SoleonAgro, which is intended for agricultural pest control.

Bat Bot, Evonik, UAVs, and 3D Printing

Chemical company Evonik, like many other chemical companies, saw the opportunity there is in 3D printing and began manufacturing materials for the technology along with its other products a while ago.

Evonik’s work with 3D printing materials has taken it into the realm of biocompatible implants, potentially leading to more effective treatment for people with serious bone injuries or diseases.

UAVs go well with 3D printingand that is a good new for anyone who, like Evonik, is considering using UAVs in large-scale maintenance operations, or for many, many other purposes.

¿Is 3D printing speeding adoption of UAVs across industries and across the world? Yes: 3D printing means UAVs are easier, faster and cheaper to manufacture, and because they’re so easy and inexpensive to create, bigger risks can be taken with their design and their usage, meaning more creative applications.

Recently, Evonik began looking into UAVs as part of its plant maintenance program. The company 3D printed a multicopter and flew it over its Wesseling site. The multicopter transmitted live images of the water tower and pipe bridges to a monitor on the control unit, demonstrating its efficacy in providing support for maintenance work. “Overall, the experiment showed that drones are ideally suited as support for projects such as maintenance work,” Evonik said.

Another good example of the good marriage between 3D Printing and UAV manufacturing is the partially 3D printed Bat Bot, a marvel of engineering, designed as an alternative to traditional quadcopters, to be used in urban areas or other cramped environments. Bat Bot was designed to be used for everything from search and rescue to personal assistance. ¿Also for military? Well, the military uses of Bat Bot can’t be ignored, as UAVs have already become critical for surveillance and supply delivery, and soldiers are beginning to 3D print their own with more frequency.
