3D Printing Blood Vessel Networks

Posted on Updated on

3-D printers can assemble raw materials into very complex products. Researchers had previously fabricated a single blood vessel, which amounted to no more than a long and slender tube. The next hurdle is to create complex, branching networks of blood vessels.

A team of engineers led by Dr. Shaochen Chen of the University of California, San Diego, aimed to improve on current 3-D printers to better engineer complex tissues like blood vessel networks. Their research was supported by NIH’s National Institute of Biomedical Imaging and Bioengineering (NIBIB). Results were published online in advance of the April 2017 issue of Biomaterials.

“Almost all tissues and organs need blood vessels to survive and work properly. This is a big bottleneck in making organ transplants, which are in high demand but in short supply,” says Chen. “3-D bioprinting organs can help bridge this gap, and our lab has taken a big step toward that goal.”

The results show that a complex tissue resembling blood vessels can be formed using a 3-D printer. The ultimate challenge for this research team is to engineer heart tissue with a complex network of blood vessels. Such tissues might be used to replace damaged heart muscle or for drug testing. 🙂

Desktop Metal has just been granted the patents

Posted on Updated on

Metal 3D Printing Patents Make it Easier to Remove Support Structures. Desktop Metal, is a Massachusetts based company that has developed office and mass production level metal 3D printers.
Desktop Metal has just been granted the patents for its proprietary Separable Supports technology.
According to Jonah Myerberg, Chief Technology Officer and Co-Founder of the company,

“As a company driven by invention, we are committed to both innovating and protecting our technology through strategic intellectual property achievements. The technological innovation in these patents enables users, for the first time, to print large metal parts with complex geometries that can be easily removed from their support structures by hand or to print metal objects with separable interlocking structures.”

“Traditional laser powder bed methods for metal additive manufacturing (AM) are restricted to single materials and are both difficult and costly to implement,” said Myerberg. “Desktop Metal has designed new approaches for metal AM that now allow multiple materials to be used during printing. This makes it possible to print support structures that do not bond to parts and consolidate during sintering with the part and, as a result, high dimensional accuracy is achieved, and support structures are easily removed by hand. We believe the benefit of this technology covered by the patents will enable substantially increased adoption of metal AM.” 🙂
