This is actually pretty amazing and could be a massive breakthrough for medical science. Yes, i know it's controversial, but it is the future, especially if we want to provide better medical care for people and make it cost effective and less invasive. Of course, it also seems a bit creepy to be 3D printing human tissue, but it's also quite incredible to think about in terms of how far medicine and technology have come. Thanks for covering this, Cabe!
So very often when we talk about advances in technology what we really have is an advancement in material. It's not so much that we have a new gadget or procedure, it's that we finally have a new material which allows us to use existing technology (a 3D printer) in new ways.
As a liver transplantee, I'm very much interested in these stories. When my new liver wears out in about 20 years, I'd love to get a replacement from my own cells and be able to get off the immunosuppressants I have to take twice daily which make me susceptible to skin cancer. It's been two years and I've already had to have two spots treated with liquid nitrogen to freeze them off.
Do we simply remove ourselves from the moral issue by casually saying, "though it's a controversial topic"? We have a responsibility as engineers to consider all aspects of our work. Yes, there are areas that though possible, interesting, intellectually challenging, and even "beneficial" for medical advancement, we must consider the cost. Destroying one human life to enhance another is not acceptable, even though it is technically possible and a really "neat" advancement!
To clarify--I read the abstract, downloaded the paper, and looked through the results. What they are doing is: (1) starting with viable embryonic stem cells, (2) putting them into a culture medium, (3) "printing" meaning using a printer like setup to form droplets droplets of cells+medium along with just medium to form (4) a droplet or blob which contains as few as 5 cells and is as small as 0.25 mm, (5) printing a grid (array) of these of various sizes and cell concentrations, then (6) inverting the droplet holder so that gravity acts on the cells and causes them to coalesce into spheriod shapes.
That's it. The "breakthrough" is controlling the size of the resulting droplets and cell amounts which would be useful in research work, and increasing the percent of cells which survive the process. No 3D. No organs coming out the end of a printer.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
