3D Printing News Briefs, January 28, 2023: Bronze-Steel Alloys, 3D Printing on Textiles, & More https://ift.tt/8norz3C We’re starting with research in today’s 3D Printing News Briefs, as a research team based out of China developed a new approach for 3D printing hydrogel-based electronics. Also, researchers in Russia are 3D printing samples of bronze-steel alloys, which could show great promise for aircraft and rocket engines. 3DEO launched a new metal for high-volume 3D printing. Finally, a new PEUGEOT concept car features 3D printing on textiles, thanks to Stratasys technology. 3D Printing Hydrogel-Based Electronics3D polymer networks called hydrogels retain large amounts of liquids, rather than dissolving in water, which makes them excellent material platforms for environmental and biomedical applications. Many electronic devices based on soft hydrogels, like sensors, artificial tissue, and drug delivery devices, have been created, but high production costs hinder widespread use. But a team of researchers, led by Dr. Nanjia Zhou at Westlake University in China, developed a new approach to 3D printing soft hydrogel electronics that could help keep costs down for hydrogel-based devices. The goal of their study was to come up with a more efficient way to print complex, biomedically useful hydrogel-based electronics, using a stretchable silver-hydrogel ink and a hydrogel-based supporting matrix. By combining granular gel particles with a conductive filler (silver flakes), they could form a segregated structure in the highly conductive 3D printing ink. The researchers tested their method by freeform printing several hydrogel-based electronics, including biological electrodes, inductors, and strain sensors, which performed very well and could pave the way for fabrication of more sophisticated hydrogel-based electronics, including biomedical devices and environmental monitors.
Novel Bronze-Steel Alloys Could 3D Print Engine Combustion ChambersA team of researchers from Russia’s Skolkovo Institute of Science and Technology (Skoltech) decided to blend the distinct properties of two metals in an “unlikely union.” The researchers 3D printed samples of a novel bronze-steel alloy that’s previously unknown to materials science, and found that the resulting mechanical characteristics could be beneficial in fabricating combustion chambers for aircraft and rocket engines, due to the capacity of bronze to conduct heat away from the chamber and steel’s ability to withstand extreme temperatures. In their study, the team used direct laser deposition, which melts and fuses powdered ingredients with a laser beam at each successive point in the metal part during its creation, and this was reportedly the first-ever synthesis of a bronze-steel alloy using this technology. The team combined the metals in two different ways: quasi-homogeneous alloys, which has the materials mostly evenly intermixed, and sandwich structures, which consists of alternating 0.25 mm thick layers of the metals. By printing vertical bars from the bottom up and examining their microstructure, shape, and chemical composition, they determined that the two materials fused well, with no defects forming.
3DEO Introduces 316L Stainless Steel for High-Volume 3D PrintingDesign, engineering, and manufacturing firm 3DEO, which is the world’s highest volume metal 3D printing service, has launched 316L stainless steel for 3D printing. The non-magnetic, fully austenitic material exceeds MIM standards, and is weldable, very corrosion resistant, and has excellent ductility and mechanical performance. In addition, it performs very well at both room and moderately elevated temperatures, and all of these features make it a good choice for applications in industries such as marine, food processing, industrial, and medical. 316L joins 3DEO’s existing 17-4PH stainless steel, and marks its latest materials expansion, though the company is currently testing several other new materials, including pure copper, that are set to be released later this year.
3D Printing on Textiles in PEUGEOT Concept CarThe new PEUGEOT INCEPTION CONCEPT car is the Stellantis Group‘s vision for the future of electric vehicles, and also features the use of 3D printing, thanks to a collaboration between Peugeot and Stratasys. The car’s name itself means “the beginning,” and adoption of 3D printing continues to grow at Stellantis, formed in 2021 on the basis of a merger between Italian-American conglomerate Fiat Chrysler Automobiles and the French PSA Group. Peugeot is actually a brand of PSA, an early Divergent investor that has used AM in the past to fabricate custom parts and accessories for the vehicle line. The floor and seats of the new PEUGEOT INCEPTION CONCEPT are covered in a special velvet, which was made of 100% recycled polyester. The velvet extends to the floor, and was then printed with 3D patterns, using Stratasys’ 3DFashion technology, to act as a car floor mat. 3D printing was also used to make final parts, like the Hypersquare control system, more comfortable by improving the ergonomics. The Hypersquare’s rim is also 3D printed. While Stellantis hasn’t yet addressed the use of 3D printing for serial part production in the PEUGEOT INCEPTION CONCEPT, but higher batch applications could be considered in the future if the value proposition fits the overall cost scheme. This could be an indication that most car manufacturers know that 3D printing could be the future.
