The Ultimate 3D Bioprinter?

3D printing is becoming a big deal when it comes to replacement parts for people. Substantial advances have been made over the past 5 years, and a new printer under development from a company called Aether looks more advanced than most others in the field.

Most printers have a relatively limited number of biomaterials (”inks”) that they can print at one time, and many of the actual materials are proprietary. They tend to be very expensive, sometimes $200,000 or more.

Aether has developed what I would call a great “pilot” printer to demonstrate that this can be done better and more cheaply. The printer in the 8 minute video is printing two pieces of bone connected with a tendon. In this case, the printer uses 6 “inks” including graphene for bones and stem cells to seed them as well as the tendon. The printer can actually print a mix of organic and organic “inks” with up to 10 syringes (”cartridges”). And in this case, it actually embeds two transistors and wires in the product. Printing bionic parts? And the final cost of this printer is projected to be under $10,000.

A number of other companies are out there competing in this market. They are providing tissue samples and skin for drug testing and research. So expect technology to advance and prices to fall as these printers become more sophisticated and more clinically useful.

Everything You Always Wanted To Know About: REBOA!

REBOA has become one of the hot topics that everyone seems to be talking about (and writing about). As with any hot new trend, it’s important to understand the facts, as much as they’ve been worked out. The enthusiasts are, by definition, always very enthusiastic, and sometimes the hype overshadows the reality.

During the next week, I’m going to methodically make my way through the basics, like what it is, how we came up with the idea, and what it entails. Then I’ll look through the literature as we know it. Finally, I’ll try to put it all together and make some recommendations about what you should be doing with it.

Tune in, starting Tomorrow!
