Complex nerves were regenerated with a 3D printed guide

There is a lot of research about nerve regeneration being made and significant progress has been made. A team of researchers from various American universities have worked on a project to develop a guide which will help complex nerves to regrow. They’ve created it by using a 3D printer. Nerve damage is usually permanent and by using advanced 3D printing methods the situation might change. This new study used 3D imaging and printing techniques to create a guide made out of silicone with biochemical cues that help nerves regenerate.

Until now, the effectiveness of the 3D printed guide was tested only on lab rats. They’ve selected the rats sciatic nerve and 3D scanned it to create its image. With a custom built 3D printer, they’ve printed the guide in a ‘Y’ shape to include both sensory and motor branches of the sciatic nerve. The guide was surgically implanted into the rat by cutting its sciatic nerve and connecting the guide to the ends of the cut nerve. It took the rat about 12 weeks to regain the ability to walk, although not completely.  “This represents an important proof of concept of the 3D printing of custom nerve guides for the regeneration of complex nerve injuries,” said professor of mechanical engineering Michael McAlpine from the University of Minnesota.

Custom guides for nerve reconstruction were previously made only for linear nerves, but this 3D printed guide is the first one made for a more complex nerve. Scientists wish to be able in the future to better customize the 3D printer to be able to create guides for human nerves.

I accept that 3D publishing exists, but honestly, I can’t really get my head around it.

Perhaps I need to start from the beginning and I suspect a little character named Leo can help. Leo the Maker Prince is a story book written for children to teach them about 3D printing. The book is accompanied by files to download that bring the characters to life.

Written and illustrated by Carla Diana, the story is about a girl (in fact a fictional version of the author herself), and her walk through the city with Leo, a robot that can turn anything she draws into plastic reality through 3D printing. Along the way, they meet other clever robots including Hi-Ho who prints in metal and Sinclair who can find and print objects from a huge catalog of designs.

Incredibly, all of the objects in the book are printable. After reading the book and being inspired by the robot’s abilities to make new parts for broken things and create new designs, kids can download files to print their own versions of the characters and objects from the book at Thingiverse. Printable objects include a sheep and musical instruments. Now I just have to get my hands on a 3D printer!

Am I any closer to really coming to grips with 3D printing? Perhaps. It’s still mind-boggling. But I do know that this technology is the way of the future, allowing designers to customise pieces and to build and produce at a fraction of the cost of traditional manufacturing. Given that our children will be the champions of the 3D printer, capture their imagination now with this interesting and unique story.

Leo the Maker Prince is available from Amazon, which ships internationally.
