Reforming surgical procedures with 3D printing hubs in hospitals

Increasingly, hospitals use 3D printing in surgery because the technology can enable fast, unique production of patient-tailored tools at relatively low costs. ‘As the technology itself is developing and accelerating at a fast pace, hospitals may be left behind if they choose not to adopt these advances,’ said Limor Haviv, surgical 3D printing designer at 3D4OP. Today, 3D printing is used in…

Gels for drug delivery systems

'Soft' 3D printing could jump-start creation of tiny medical devices

Researchers at the U.S. National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as…

The science behind 3-D printed nasal swabs

Medical device approved 3-D printers are producing clinically safe and effective nasopharyngeal swabs for COVID-19 testing. A nasal swab may seem rudimentary, but is essential for testing COVID-19. Diagnostic test kits and components – nasal swabs, collection vials, and chemical reagents – have been in short supply worldwide, especially in March. Ironically, nasopharyngeal swabs are…

New 3D CT scanning method shows what happens during CPR

Rapid first aid during cardiac arrest makes the difference between life and death. But what happens to the heart and the internal organs when people come running and begin to give well-meaning but heavy-handed heart massage as they attempt to keep the person who has suffered a cardiac arrest alive? A research collaboration between the Department of Forensic Medicine at Aarhus University and the…

3D imaging shows how diabetes twists nerve fibers

In an international collaboration led by Lund University in Sweden, researchers have used synchrotron light to study what happens to the nerves in diabetes. The technique shows the 3D-structure of nerve fibers in very high resolution. “This knowledge can be used to map mechanisms for how nerve fibers atrophy and grow back. It means that we can better understand how diabetes affects the nerves…

New imaging technique to study 3D printed brain tumors

Glioblastomas are complex, fast-growing malignant brain tumors that are made up of various types of cells. Even with aggressive treatment — which often includes surgery, radiation, and chemotherapy — glioblastomas are difficult to treat, leading to an average survival of 11-15 months. In research published in Science Advances, Xavier Intes, a professor of biomedical engineering at Rensselaer,…
