3D printing of nanomaterials and implanted prosthetic limbs.

Long-time readers of my site no doubt know of my fascination with the field of 3D printing and tracking the advances that are made almost weekly to this technology. From simple plastic tchotchkes to replacement parts to materials that few ever dreamed would be used, 3D fabbers are fast becoming an integral part of manufacturing at all levels of complexity. A few months ago researchers at Lawrence Livermore National Laboratory published the results for a revolutionary 3D printer called the Optomec Aerosol Jet 500, a fabber which uses a range of nanomaterials as its feedstock. To cut to the chase …

Cardiac prosthetics and fully implanted artificial limbs.

No matter how you cut it, heart failure is one of those conditions that sends a chill down your spine. When the heart muscle grows weak and inefficient, it compromises blood flow through the body and can cause a host of other conditions, some weird, some additionally dangerous. Depending on how severe the condition is there are several ways of treating it. For example, my father in law has an implanted defibrillator that monitors his cardiac activity, though fairly simple lifestyle changes have worked miracles for his physical condition in the past several years. Left ventricular assist devices, implantable pumps …
