Saab flight tests 3D-printed repairs on Gripen fighter jet

Swedish aerospace and defense company Saab has successfully conducted a flight test that has shown how additive manufacturing can be used to repair battlefield damage on its Gripen fighters.

The test flight, which took place at Saab’s facilities in Linköping, Sweden on March 19 marks the first time an exterior 3D-printed part has been flown on a Gripen, rather than internal 3D-printed components.

The  Gripen was fitted with a replacement hatch that had been 3D-printed using additive manufacturing, using a nylon polymer called PA2200.

The project is a step towards 3D-printed spares being used for rapid repairs to fighter aircraft that have sustained damage while deployed on remote operations, thereby gaining a vital time-saving advantage, said Saab.

Naval 3D Printing grows with DNV verification of 3D printed crane

The maritime sector is one of the more overlooked segments in 3D printing, with only a handful of companies really taking advantage of the opportunities there. A new business involved in 3D printing for naval uses has made itself known, Austal Australia, who, along with its partners, AML3D (ASX:AML) and Western Australia’s Curtin University, has 3D printed an aluminum personnel recovery davit. The device has been verified by DNV, the world’s largest classification society at its Global Additive Manufacturing Technology Centre of Excellence in Singapore.

According to international and naval specifications, Austal, AML3D and Curtin University produced a three-meter-long crane, also known as a davit, designed for personnel recovery. The assembly was then tested to support over two times its intended working load. This was followed by non-destructive and destructive testing. The testing process included microanalysis of the microstructure of the aluminum parts, with mechanical and corrosion properties compared to those of traditional marine grade materials.

French soldiers deployed to Mali use 3D printers to make spare parts

French soldiers deployed to Operation Barkhane in the Sahel have been experimenting for several months with 3D printers to make spare parts at their base in Mali.

According to a Ministry of the Armed Forces release, Desert Tactical Group – Logistics “Charentes” is responsible for testing the feasibility of using the two 3D printers at the large base in Gao to make components.

In general, the specialists at the base a tasked to produce replacements for broken components.

They follow a familiar process – first modelling the part on a computer and then printing, testing, iterating and refining where necessary.

Small parts can be printed in minutes and more complex projects within hours, saving time and effort in transporting equipment to the relatively remote base in central Mali.

UK MoD to harness AI and 3D printing in new relationship with industry

The Ministry of Defence (MoD) has unveiled a new approach to harnessing emerging technologies like AI and 3D printing.

The Defence Technology Framework and Defence Innovation Priorities have set out how the Government will address the accelerating pace of technological change in the years to come.

MoD to harness AI and 3D printing in new relationship with industry

This includes identifying technologies that can revolutionise defence as well as outlining a more sophisticated relationship with industry.

The documents respond to the Modernising Defence Programme, which was launched in January 2018, and outlined its conclusions later that year.

3D printer makes peacekeeping missions cheaper and repair of defense systems faster

Peacekeeping missions often take place at remote locations, requiring the army to have a large supply of spare parts on site to keep everything running. Dutch researcher Bram Westerweel comes to the conclusion that taking a 3D printer on a mission to print parts can save hundreds of thousands of euros and, at the same time, reduce the downtime of defense equipment. The savings on operational costs sometimes total more than half. The findings of Westerweel, who received his Ph.D. yesterday, can also be applied to industries with remote locations, such as the offshore industry.

Quick return on investment

The army’s systems have many thousands of types of spare parts. Based on his research, Westerweel expects that a total of 10-20 percent of the components of the armed forces can be made by additive manufacturing, also known as 3D printing. The total savings by 3D printing on relatively large peacekeeping missions like the ones in Mali and Sudan, could then run up to hundreds of thousands. The printer itself costs a one-off €25,000, making for a quick return on investment. The Dutch army is already experimenting with such a printer in Mali.

3D printing technology enhancing logistics for Army

A Soldier holds a cap used to protect the fire extinguishing system housed in the wheel wells of Mine-Resistant Ambush Protected vehicles. Without the cap, MRAPs are deemed non-mission-capable. Soldiers in Korea saved 1,472 operational days for their MRAPs by 3-D printing the caps for about $2.50 each.

FORT MEADE, Md. — As 3D printing increases both in the field and at depots, the Army’s Center of Excellence for Additive and Advanced Manufacturing is slated to reach initial operating capability this year at Rock Island Arsenal, Illinois.

Lt. Gen. Aundre Piggee, the Army’s deputy chief of staff, G-4, outlined the Army’s current 3D printing capabilities at the 2019 Military Additive Manufacturing Summit and Technology Showcase Feb. 6, in Tampa, Florida. 

At the summit, defense, academia, and industry officials were privy to the latest additive manufacturing technologies, event officials said. The Army will leverage these improved 3D printing capabilities to bolster equipment readiness and reduce logistics burdens, Piggee said.

At the U.S. Marine Corps Air Station (MCAS) Iwakuni, southern Japan, 3D printing is now in use to keep F/A-18 Hornet multirole fighters airborne.

MCAS Iwakuni engineers have devised two products that reduce the time it takes to repair the fighter jets, saving costs for the U.S. Department of Defense. The products help with the maintenance, repair and overhaul (MRO) of the fighter jets, covering all tasks carried out to ensure the airworthiness of an flight vehicle.

The 3D printed products include an engine ship kit, designed by the Marine Aviation Logistics Squadron 12 (MALS 12), and a plastic ring kit that helps the maintenance of the bearings on the F/A-18’s Gatling gun.
