Researchers at the University of Iowa College of Engineering’s Center for Computer Aided Design have developed a rather interesting prototype bioprinter, capable of printing living tissue. The device, made by Ibrahim Ozbolat, assistant professor of mechanical and industrial engineering and doctoral student Howard Chen, does something no other 3D printer can do, whether for bioprinting or non-bioprinting: print with multiple arms simultaneously.
The problem with multiple arms is that they can easily crash into each other. Solving this problem is so difficult that all other 3D printing approaches simply avoid the problem by having only one printing arm in motion at a time. There can be no collisions if there’s only one arm.
Somehow the UI researchers developed an ingenious solution to this challenge and their new (unnamed) bioprinter is capable of very complex print operations involving multiple arms. This permits much more rapid printing of living tissue, which frequently involves multiple materials (e.g. embedded blood vessels, surfaces, muscles, etc.) We suspect there are severe time limits involved when printing living matter, while “normal” 3D prints can freely take many hours or days to complete.
What are the researchers printing? They’ve developed a potentially game-changing item:
One of the most promising research activities is bioprinting a glucose-sensitive pancreatic organ that can be grown in a lab and transplanted anywhere inside the body to regulate the glucose level of blood.
Kerry Stevenson, aka "General Fabb" has been writing Fabbaloo posts since he launched the venture in 2007, with an intention to promote and grow the incredible technology of 3D printing across the world. So far, it seems to be working!

Welcome to Fabbaloo, one of the world’s oldest online news sources for 3D printing news. We’ve been in operation since 2007, where we first started examining the state of 3D printers. These devices are now relatively common among some circles in today’s world, but years ago it was extremely rare to see a 3D printer or even a 3D printed object.
At that time it was challenging to find any 3D printing news, so we decided to make our own site that covered 3D printer news, and even associated technologies like 3D scanning and 3D modeling. Today it is common to find 3D printers in schools, workshops and makerspaces, and you probably have been using 3D printed objects without even knowing they were 3D printed.
Today’s industry has finally taken up the challenge by installing thousands of industrial 3D printers, each producing previously impossible 3D printed parts that make today’s society far more efficient. The aerospace industry in particular has been producing many 3D printed parts, some even for flight critical purposes.
If you want to learn about 3D printers, then there’s no better place than Fabbaloo’s 3D printer news to see the latest happenings.
