The 2 meter long version of  Peng's boat

Over the past year, we have seen many incredible 3D printing projects take place. There have been houses, cars, boats, and prosthetic hands that have all been created on 3D printers. However, one artist, named Hung-Chih Peng, may have them all beat, at least when it comes to creativity and time involved.
The 2 meter version
Hung-Chih Peng is a Taiwanese artist who thinks outside of the box, and I’m not just talking about throwing in a few extra colors on a painting, or sculpting a slightly controversial scene. He has garnered a tremendous amount of attention with his unique exhibits such as Post-Inner Scripture in 2013, God Pound and 200 Years in 2009, and Little Danny in 2002, among others. Now Peng’s latest work is The Deluge – Noah’s Ark, which is currently an exhibition that can be seen at the Taipei Fine Arts Museum. It takes a model of a boat, and twists and turns its body in a way that isn’t physically possible in the real world.
But this is art, and The Deluge is Peng’s way of showing the inability that humans have exhibited in rectifying uncontrollable catastrophic challenges. Climate change, ecological crises, and environmental pollution are all changes that this planet is facing, yet seemingly humans do not have a way to correct these problems. The work is meant as a metaphor for showing the battle being waged by Mother Nature on the accelerated development of industrialized civilization. And as Peng explains:
“Human beings are unable to return to the unspoiled living environment of the past, and have become victims of their own endeavors. In the biblical time, Noah’s Ark is the last resort for humans to escape from the termination of the world. However, if Noah’s Ark sinks, where is the hope of the human race? If Noah’s Ark, a symbol of mankind salvation, becomes just as a shipwreck, human and nonhuman were placed in an equal position. Human subject is losing his predominance as the supreme center of the world.”

Currently on display is this piece which Peng has created. It is 3D printed and measures 2 meters long. It depicts a time when the Anthropocene period (a period when human activities have/had significant global impact on Earth’s ecosystems), is replaced by the Mechanocene period when machinery begins taking over some of the jobs.
“It is certain that, no matter what circumstance will turn out, there will certainly be a disaster beforehand,” explains Peng. “Destruction and construction always grow and demise together. We will once again encounter the problem of moral degeneration.”
As part of the exhibition that features Peng’s 2 meter long “Noah’s Ark,” which has been twisted and turned in all directions, he has also turned his exhibition space into what he terms “an artist’s studio,” and is currently 3D printing a HUGE 26-foot-long model of the same boat, using 30 UP 2 FDM-based 3D printers. In all, there will be about 100,000 separate 3D printed pieces that will go into assembling this giant boat.
The 8 meter (26 foot) 3D printed boat - printed in 100,000 pieces.
“The boat is not finished yet, it will be finished at the beginning of Jan 2015,” Peng tells 3DPrint.com. “It will be 8 meters long and about 165 cm high and wide. We will use 560 kg of filaments, sponsored by UP printer maker, Beijing Tiertime. This is my first time using 3D printers. The original idea was only to build a huge twisted boat for this biennial. It has to be huge. After evaluating all the possibilities of different working processes, we think 3D printing is the best final decision.”
Visitors to the exhibit can see first hand as 30 3D printers are constantly working, printing different parts of the boat. When finished, they are assembled onto the larger model, which also is currently on display.

Help for the people without limbs

How can 3D printing help those with paralyzed limbs?

On this page we’ve shown you many different forms of prosthesis created thanks to 3D printing that has changed the lives of many people with missing limbs.

Now take a look at a project which, using 3D printing, can help people with paralysis gain control over their affected limbs again 🙂

We have seen many extremely helpful 3D printed prosthetic hands and arms come to fruition over the past two years. Thanks to groups like e-NABLE and the Robohand Project, there are hundreds of people who now have gained use of both of their hands. The incredible thing about 3D printing is that it allows for the fabrication of completely custom devices, at costs of under $50. Traditional prosthesis cost up to 10,000 times this price, and many of these expensive devices don’t even function as well as their cheaper, home-fabricated counterparts.

3D printed prosthetic hands have been a life saver for individuals (mainly children) who have been born with missing hands, or partial hands. These devices allow them to gain use of an appendage that they never had the ability to use before.  With this said, what about those individuals who have their entire arms and hands intact, but for one reason or another don’t have the ability to move them?

There are many medical issues that can cause paralysis of a limb and/or appendage. They range from muscular dystrophy, to arthritis, strokes, nerve damage, and in this particular case a child who was forced to have a hemispherectomy (removal of half of their brain). Devices to help aid these people are not all that common, and if one were to get their hands on such a device, it could cost upwards of $50,000.

Elizabeth Jackson Models the Airy Arm (image source: Brain Recovery Project)

This is where one young lady, named Elizabeth Jackson comes to the rescue, thanks in part to 3D printing technology. Jackson, a member of e-NABLE, and a student of e-NABLE’s “leader”, Jon Schull at RIT(Rochester Institute of Technology), decided that something needed to be created for those without functioning arms/hands. Building on previous work by fellow e-NABLErs Ivan Owen (University of Washington Bothell) and Jean Peck (Creighton University, Omaha), Jackson came up with what she calls the “Airy Arm”.

“The Airy Arm is an exoskeletal device that assists individuals with intact but non functioning hands,” Elizabeth Jackson tells 3DPrint.com. “For example, the child that this was designed for had half of his brain removed which resulted in the paralysis of his wrist and hand. No electric components are used, and the hand is instead driven by the user’s own controlled movement of the elbow.”

The device works with cables that run over and under the fingers and then attach to the elbow. The hinge, located on the elbow, pulls on the cables under the finger and then forces the hand to close, as the elbow bends. When the elbow is straightened, the inside of the elbow pulls the strings located on the back of the fingers, thus opening the hand. This means that when the user reaches for an object, the strings pull the fingers open, and when the user pulls that object back toward his/her body, the fingers are forced to close. A double hinge on the elbow allows the user to have free movement without any interference or irritation of the skin. The underside of the fingers are strung with elastic, which enables the user to hold objects of different sizes, quite comfortably and confidently.

“The frame of the Airy Arm is 3D printed flat from a plastic called PLA (polylactic acid), and is then dipped in hot water and molded to the user’s hand and arm in order to form a comfortable fit that is flexible and lightweight,” Jackson told us. “Printing the pieces flat also decreases the print time and the amount of material used. This device would be useful in a variety of situations, including partial paralysis, stroke victims, and individuals with arthritis or muscular dystrophy.”

Recently at a large e-NABLE event, Jackson had the opportunity to show this device off to the innovators, medical personnel, and fellow e-NABLE members on hand. “People were very excited about the concept,” explained Jackson. “It is revolutionary, and can help so many more people than I ever anticipated. It has been getting very little media attention, as it is still a prototype, but somehow people still heard about it and were excited to actually see it in person.”

There is so much potential for devices like this. Just imagine how many people would love to have such an apparatus enabling them to once again gain use of both hands. Jackson will be working for the Brain Recovery Project, starting in January, in an attempt to create a final design for this device, and get it working for several patients who they work with. The Brain Recovery Project works with children who have experienced severe epilepsy, and were required to have half of their brain either removed or disabled. These children become paralyzed on the opposite side of the body that their brain was removed from, and devices like what Jackson has come up with can help them regain function once again.

If you are interested in donating to the Brain Recovery Project, you can do so on their website.

If all goes as planned, then perhaps one day soon, anyone will be able to print their own Airy Arm for personal use, or for use by family and friends.  This is why 3D printing is such a great tool.  It allows for open source designs that are able to be fabricated via downloadable files.

What do you think? Will this device provide as much of an aid to users as some of the 3D printed prosthetic hands we have seen? Discuss in the Airy Arm forum thread on 3DPB.com.
