A team of doctors in The Netherlands performed successful jaw transplant surgery recently that showcases just how far the power and potential of 3D printing has come as key asset in medical applications, particularly the design and development of custom prosthesis.
An 83-year-old woman suffering from a chronic bone infection received a lower jaw transplant of a 3D-printed jaw made out of titanium powder as opposed to undergoing reconstructive surgery, which the medical team deemed too risky because of her age. Using a 3D model of the patient's lower mandible, the medical team, in partnership with metal additive manufacturing provider LayerWise, constructed and 3D-printed a metal jaw implant structure that incorporates articulated joints and dedicated features, becoming one of the first complete patient-specific implants, according to officials.

Additive manufacturing technology was a natural fit for this application because the process doesn't face any restrictions in terms of producing the complex lower jaw implant structure unlike other technologies, which could require multiple metalworking steps. In addition to LayerWise, the method was developed by the biomed research group at the University of Hasselt in collaboration with engineers from Xios Hogeschool, Xiloc Medical BV, and the University of Leuven. Maxillofacial surgeons from the Orbis Medisch Centrum Sittard-Geleen were also heavily involved.
Medical applications are one of the key areas where industry experts expect 3D printing technology to take off. Use of 3D printers and advanced 3D modeling software technology for producing dental structures and orthopedic prosthesis is becoming more commonplace, and there have been industry reports of 3D printers being used in making other body parts, including blood vessels, and growing new bones. There's even futuristic talk of replacing the metal powders commonly used in 3D printing with organic tissue and bone material, which would essentially function as the "ink" for the 3D printing process.
That would be really great if the technology could advance to support that application, Greg. We all know any kind of innovation to help wounded vets lead a normal and functional life is well worth it.
@gsmith120: There does seem to be a lot of activity around 3D printing and dental applications. Check out EOS, a manufacturing of laser sintering platforms. I believe they do a lot of work in the dental segment. Perhaps they have partners using their platforms to create something that could help your daughter.
Nice article. My daughter is missing two teeth (never had baby or permanent) and we have been looking at some new technology can would/could allow her grow replacement teeth. That research has been to be somewhat slow maybe this will be a good option.
I agree, Beth, and I'm sure they will be welcomed by legitimate users. Unfortunately, the illegal organ trade is alive and well in today's supposedly regulated world, which makes me wonder about the illegal trade that could occur in 3D printed organs.
In an unregulated world, you're right, Ann. It would be pretty scary. I guess my brain doesn't work that way. I was just thinking that for qualified/certified and totally above board medical institutions, it would be a welcome alternative to organ transplants or the worse alternative--patient loss.
Beth, I hope you are right. maybe I read too much science fiction, but the idea of being able to not only fabricate, but 3D print replacement organs makes me pretty uneasy. OTOH, maybe it would help stop the illegal live/fresh organ trade.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
