Russian Scientists Successfully Implant 3D-Printed Thyroid Gland

A Russian company announced a successful experiment implanting 3D-printed thyroid glands into mice, and the results will be published next week, said Dmitri Fadin, development director at 3D Printing Solutions.

“We had some difficulties during the study, but in the end the thyroid gland turned out to be functional,” Mr. Fadin told RBTH. Continue reading “Russian Scientists Successfully Implant 3D-Printed Thyroid Gland”

Carnegie Mellon Researchers Try to Rebuild Hearts Using Biomaterials Printed with Inexpensive Printers (Video)

As of this month, over 4,000 Americans are on the waiting list to receive a heart transplant. With failing hearts, these patients have no other options; heart tissue, unlike other parts of the body, is unable to heal itself once it is damaged. Fortunately, recent work by a group at Carnegie Mellon could one day lead to a world in which transplants are no longer necessary to repair damaged organs.

US Researchers Develop Biomaterial that Could Be used to Print Load-Bearing Body Parts such as Knee Cartilage

Printing replacement body parts may sound like something out of a sci-fi novel, but since 3D printing was introduced in the 1980s, scientists have been aspiring to make this a reality. Now, a team from Texas in the US has developed a super tough biomaterial that could be used to print load-bearing body parts such as knee cartilage.

The Texas team 3D printed a meniscus out of an alginate-containing hydrogel Continue reading “US Researchers Develop Biomaterial that Could Be used to Print Load-Bearing Body Parts such as Knee Cartilage”

First Living Cellular Bioink Kits to Be Made Commercially Available

Sometimes it is difficult to tell the difference between news about advances in medicine and the plot for a B movie horror film. The latest developments related to bioprinting are just that kind of material and yet they are part of what is actually happening as medicine and 3D printing technology continue to work together. Just this week, CELLINK and RoosterBio have announced a partnership that allows them to pool their complementary technologies and make Cellular Bioink Kits commercially available. Continue reading “First Living Cellular Bioink Kits to Be Made Commercially Available”

3D Bioprinting’s Allure Attracts Blooming Interest from Skincare Industry

3D bioprinting’s allure has attracted blooming interest from the skincare industry, with three leading firms each launching skin printing initiatives in mid-2015 that they hope will revolutionise cosmetic testing. The initial challenge is making skin slivers for new product experiments conducted in multiwell analytical plates, but success could lead to much grander schemes. The expertise gained could feed into pharmaceutical research, and even help enable patients’ own cells to be made into almost perfectly compatible skin grafts and eventually replacement organs.  Continue reading “3D Bioprinting’s Allure Attracts Blooming Interest from Skincare Industry”

Researchers Develop 3D Printing in Gel Technique that Can Be Used in Tissue Engineering (Video)

To improve 3D printing, simply add gel. A fresh technique uses one to support complex shapes that would fall apart under their own weight in normal 3D printing.

This new-found combination of strength and delicacy will be crucial if we’re ever to print the biological structures that make up organs, blood vessels and other tissue.

The gel, which has the consistency of hand sanitiser, is made of an acrylic acid polymer. It works like a scaffold, allowing the printing of intricate patterns that would collapse without its support – such as nested Russian-doll-like structures and thin, complex branching networks.
