Researchers at North Carolina State University have developed a new self-healing composite that can repair itself in place without removal. The technology addresses two longstanding challenges, increasing the lifespan of structural components by up to 500%. This resolves limitations such as overheating and limited self-repair cycles.
Researchers at Fudan University reviewed fundamental mechanisms and recent developments in selective laser sintering of polymers. The study highlights the need for innovative materials, sintering methods, and post-processing techniques to improve the efficiency and performance of SLS polymer parts.
Researchers at UCF's COSMOS Lab developed a method to create strong bricks from lunar regolith using 3D printing and binder jet technology. The bricks can withstand extreme space environments and are suitable for constructing off-world structures, paving the way for sustainable space construction.
Scientists have successfully printed thin, one-millimeter-thick permanent magnets using selective laser sintering, retaining suitable characteristics for industrial use. This breakthrough enables complex magnet configurations necessary for pacemakers and minimizes production waste.
Researchers at NC State University have developed a reproducible method for studying cellular communication in plant cells using 3D bioprinting. The study found that more than half of the bioprinted cells were viable and divided over time, with soybean embryonic cells remaining viable for two weeks after bioprinting.
Researchers have developed stronger and more ductile microlattice materials by reducing unit sizes from 60 μm to 20 μm, enabling tailoring of mechanical properties. The size effect results in higher fracture strain and strength, making these materials suitable for various structural and functional applications.
Researchers developed in-situ Ni alloying method to tailor microstructure and enhance strength of LAAM Ti-6Al-4V alloy. The results show that Ni addition increases yield strength and tensile strength while decreasing ductility.
Researchers developed a generatively designed patient-specific bone fixation device using Generative Design technology. The implants are tailored to each patient's anatomy and biomechanical needs, resulting in lighter, less prominent, and minimally invasive designs that promote faster healing and reduced revision surgery.
Researchers at Lancaster University found that 3D printed flavor-based cues can stimulate rich sensory accounts and strong emotional connections in older adults, recalling memories from their youth. This technology has potential applications for dementia care, allowing individuals to relive cherished moments through the power of smell.
Researchers at Heidelberg University developed 3D printed microscopic octopuses with 'life-like' properties using smart polymers. These structures can be tuned on demand and have dynamic chemical bonds that allow them to grow and harden in a few hours, enabling complex micrometric structures.
A team of Swiss researchers has developed Aerial Additive Manufacturing (AAM), a system that uses flying drones to print materials for construction projects. The technology enables on-site manufacturing and building in difficult-to-access or dangerous locations, such as post-disaster relief construction and tall buildings.
A team of researchers from NIST, UW-Madison, and Argonne National Laboratory identified key compositions that enable consistent 3D-printing of 17-4 PH stainless steel with favorable properties. The new findings could help producers cut costs and increase manufacturing flexibility.
Researchers have developed a technology using flying robots that mimic the collective building methods of bees and wasps to construct and repair large structures. The Aerial Additive Manufacturing system consists of drones that work autonomously but are monitored by human controllers, adapting their techniques as needed.
