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.
Companies that sell consumer electronic goods in the European Union (EU) will be obliged to ensure they can be repaired for up to a decade, as a result of new Right to Repair legislation passed by the European Parliament.
3D Printing Industry asked EOS, Spare Parts 3D, DiManEx, Ricoh 3D and Link3D for their thoughts on how 3D printed spare parts could help consumer appliance manufacturers adhere to the legislation, while avoiding large physical stocks of replacement parts and subsequent incurring costs.
From summer 2021, the new EU Ecodesign and Energy Labelling regulation will give consumers the ‘right to repair’ on the goods they buy, meaning manufacturers will be legally required to make spare parts for products available to consumers for up to 10 years. The goods in question include refrigerators, dishwashers, hairdryers, lights, TVs, and so on, although appliances such as phones and laptops are not covered by the new laws.
Optomec has recorded more than 10 million turbine blade refurbishments with its metal 3D printing technology after conducting a recent customer survey.
The company says it now has more than 100 customer installations of its metal 3D printing systems specifically for gas turbine components repair, with installations made at leading gas turbine original equipment manufacturers (OEM) in the aviation and energy markets, such as GE, as well as many third-party maintenance repair and overhaul (MRO) shops.
At these companies, Optomec has installed its LENS brand Metal Additive 3D printers and Huffman brand 5-axis Laser Cladders, both based on Directed Energy Deposition (DED) technology. Customers are said to value Optomec’s proficiencies in adaptvie control software, controlled inert atmosphere processing for superior metallurgy, turn-key repair process recipes and automation solutions that facilitate higher throughput batch processing.
Automated road repairs using 3D printing could save money and reduce disruption, reports Kristina Smith
It’s the middle of the night and in the street below a team is busy carrying out repairs to the road surface. But there isn’t a human in sight.
A road-repair drone has landed at the site of a crack and a 3D asphalt printer is now busy filling in that crack. A group of traffic cone drones have positioned themselves around the repair location to protect the repair drone and divert traffic around it.
