Top 5 Videos: 3D Printed Artificial Muscles

It’s finally Sunday again! We have, as we do every Sunday, selected the most interesting and exciting videos from the world of 3D printing! Our first video today shows you how scientists were able to create a 3D printed prototype of an artificial human hand! Then, you learn more about 4D printing technologies. Following that, you’ll see a report on the increasing threat of 3D-printed ghost guns, and then you see the process of creating an authentic-looking 3D-printed cobra. Our last video from this week’s top five videos shows how 3D scanners can be used on motorbikes. We hope you’ll enjoy this week’s collection and wish you an amazing Sunday!

Top 1: 3D Printed Artificial Muscles

The following video shows how it is possible to mimic the muscles with the help of 3D printing. Corrado De Pascali, a PhD-student at the Italian Institute of Technology in Genoa, and his colleagues developed a 3D printed prototype of an artificial hand. The team created what is called GeometRy-based Actuators that Contract and Elongate (“GRACE”), by using a flexible resin that enables them to stretch and contract, just like human flesh and muscles.

Top 2: A Closer Look at 4D Printing

We all know that 3D printing technologies are quite the innovation already, but have you ever heard of 4D printing? This brand-new discovery, which is basically an advanced form of 3D printing, adds another factor to the 3D printing process: time. Take a look at the interesting video below, in which the process is explained in more detail!
