The patient had his nose damaged by an injury and then also ravaged by infection.

Need a new liver, pancreas, or other vital organ, then I’ll 3D print one right up for you…that is in about 10 years. My intern Lakshmi did a great job on her guest piece last week on the promise of 3D printing in stem cell-based bioengineering including organ and tissue production. It’s an incredibly exciting area of biomedical science. In theory in the future we could literally have new organs printed by specialized forms of 3D printers (e.g. see the image of a 3D printer at …Read More

Imagine a world in which doctors send microscopic biological machines made by 3D printing—biobots—inside our bodies to heal disease and fix injuries. A few decades ago, this kind of technology was only manifesting as the fanciful gadgets of science fiction movies. For example, the 1966 movie ‘Fantastic Voyage’ featured miniaturized objects performing a range of interesting functions inside the human body. Today, such biobots have become much more than science fiction. In many ways, what was previously envisioned in sci-fi movies has now become …Read More
