Design News you can use. I have just been diagnosed with Idiopathic Pulmonary Fibrosis. I'm 66 years old and was planning a long retirement after a career as an automotive engineer. Now the prognosis is 3 to 5 years with the possibility of a lung transplant in the future. There is currently no cure.
I will be following this project with great interest.
Doug, excelent article, I wish if in addition to the interdicipline mentioned in another post, at some point there is an story about the equipment used for the CAD design and the Additive Manufacturing.
Hi Alex. I am the lead researcher on the work and Doug asked me to log in and comment about our research team. Our cross-disciplinary team involves the following:
* One specialist in microfabrication and microfluidics (myself)
* One cardiothoracic surgeon and one pulmonary physician
* Two experts in bio- and blood- compatible coatings
* One expert in biomimetic artificial vasculature who also has some previous experience in artificial lung design.
As you can see, we have quite a wide array of backgrounds which are all needed to make this project a success. However, as part of this project, we are all experiencing some cross training which is making us better at what we do as well.
Please let me know if you have any other questions.
I absolutely agree Ohms. The human body is a wonder that no engineer or scientist could ever begin to replicate in a meaningful way. The great advance I described at CWRU only lasts a few hours in the lab. We are taking steps tinier than the tiniest baby steps. And even those accomplishments are inspiring.
Any attempt to mimic human parts will be humbled by the truly amazing human ability for reliability, performance and size and certainly requires expertise in dozens of fields of science.
Considering we can survive contstant attack of viruses and bacteria and other parasites. Also we don't often rust, or need a power flush, routine change of antifreeze or need CLR flush treatments and use nano-osmotic effects to exchange CO2 for O2 and aren't affected much by microwave and RF ringing thru our lungs and can cough sputum if needed.... and oh ya have an automatic or manual feature with a lifetime warranty on the air pump in our bellies.
.... a man-made design has a tough job to mimic a lung, in literaly hundreds of different chemical/physical properties.
There is usually great interdisciplinary involvement in these types of projects. Usually mechanical engineers are involved. And yes, these people really know their stuff. They are plumbing whole new depths of knowledge unknown in traditional corporate development projects. I have been really impressed with the level of understanding these groups have in areas of polymer science where corporations have largely given up --- polymers for implants. I touched on this recently in another post. Very specialized groups are operating under the radar to develop bioresorbable polymers for implants, for example. This project also shows the tremendous potential for additive manufacturing in microfluidics.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
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 discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
