3D printed robots again popular ?

The Never-Ending Battle Against Litter May Change Forever if 3D Printed Robots Become Popular

I frequent the famous white-sanded and turquoise-watered beaches of the Florida panhandle. And, as much as we say it over and over, it IS infuriating to see trash on the ground and in the water.  This is especially a problem during Spring Break all over the United States. Where I walk, I could spend the hour just picking up plastic bottles and aluminum beer cans–but I gave that up because they keep reappearing. Well, if one designer has her way there may be a new beach cleaning ‘Doctor’ in town.  Mingyu Jeong designed a concept for what could best be described as an automated robotic beach cleaner with a built in 3D printer.  Called Dr. Recare, it could change the way we deal with litter.  Could this concept become a reality?

Dr. Recare is a 3D printing robotic “doctor” designed with the mission of a superhero (or superhuman): it can supposedly easily, efficiently–and triumphantly once and for all?–clean up our beaches while we still enjoy the sand and waves. This machine works in a way that I would not have easily imagined would be efficient, and I have questions about cost.

Dr. Recare cleans sand itself by acting as a plastics recycler — on site. It extracts and heats up plastic garbage, then turns the plastic into 3D printer filament which it uses to 3D print recycling bins.  You can view the whole process here.

Part of the reason we are in the position we are in regarding beach pollution is there has been massive oil spills and no efforts to support the clean-up from the front line plastics production side of the issue.  (We can simply stop producing more trash.)  Oil companies spill with little repercussions, humans litter, and beaches get junked: but what’s the actual expense, and is on-site recycling via 3D printing with the trash a solution?

For example, on Panama City Beach, Florida you see tons of trash on the beaches at Spring Break.  This, and participants’ behavior,  has caused locals to call for canceling Spring Break altogether — which is impossible to do.  Now that we have located the problem of making clean up attractive with Dr. Recare’s help: maybe Spring Break beaches could showcase this as an educational tool, or a student volunteer opportunity, if it’s ever actually manufactured.

You can see by the size of the above crowd, on site stations could be established and highly functional.  People are still needed to run these machines, ultimately, but they showcase 3D printing technology and the significance of the actual behavior of generating so much waste by recycling it in front of users’ eyes on location.  I see Dr. Recares as being one way to approach recycling plastic into something useful–but we still want to stop generating plastic bins at some point too right?  The educational aspect of this design is its best feature — and I would love to go see them out on site at our next Spring Break!

Highly trafficked beach locations also feature events like Pirates’ Day and many concerts.  These are the days that public education is most possible for things like 3D printing.  When I look at 3D printing projects, I want to see a holistic design effort that also views the environmental costs of actually making the machine itself.  If it can be integrated into holistic public education and practical beach clean-up efforts, without being touted as the “answer”: I am all for it.  Let’s get started yesterday!  Let’s hear your thoughts on this concept.  Discuss in theDr. Recare forum thread on 3DPB.com.

3D printed houses

First there were 3D printed robots.

Then there were 3D printed houses.

Now, there are robots, with 3D printed parts, 3D printing houses!

It is amazing how quickly the technologies around 3D printing have been developing over the last couple of years. Not only are we seeing Moore’s Law-like increases in the speeds of these prints, all the while prices are dropping substantially, but entirely new innovative approaches seem to emerge each day.

For instance, we have already seen 3D printing drones, combo 3D printer/CNC machines,  a 3D printing assembly line, and all sorts of crazy new ways to print with food. Today a unique, but quite innovative approach to 3D printing has been unveiled by a team of researchers at the Institute for Advanced Architecture of Catalonia (IAAC), based in Barcelona, Spain.

One problem with 3D printers today, is that their build envelopes are limited by the size of the actual printer. In order to print a house, you need a 3D printer which is larger than that house. This severely limits the utility of any one device, and equates to substantial costs for any person or company trying to print on a large scale. A team of researchers, led by Sasa Jokic, and Petr Novikov at IAAC, and includes Stuart Maggs, Dori Sadan, Jin Shihui and Cristina Nan, have invented and worked diligently on a method of printing large scale objects, such as buildings, with mobile 3D printing robots they call Minibuilders.

“Within the construction industry we haven’t seen any disruptive technologies being introduced for almost a century,” stated the IAAC research team. “We believe that robotics and additive manufacturing will play a key role in the construction industry of the future.”

The Minibuilder lineup consists of three different robotic devices, each with dimensions no larger than 42cm. Despite their small size, they are capable of printing buildings of almost any proportion. All three robots, all responsible for different functions, are required during any large 3D printing project.

Foundation Robot
This is the first robot to enter the construction site. It uses tracks as well as a line-follower sensor to move around and recognize curves of a project. The side of this robot holds the actual print head, which can gradually move up as the printed object builds upon itself. Once the object gets higher than the reach of the Foundation Robot’s arm, it’s time to move to the next Minibuilder.

Grip Robot
This robot clamps itself to the top of a build project, using four rollers. Each of the four rollers are connected to rotational and steering actuators, allowing the robot to position itself on a very precise area of the structure to begin printing. This robot uses the previously printed structure as a gripping support, so the material needs to dry extremely fast to allow it to support the next layer of the print. To do this, the Grip Robot uses heaters to cure the material as fast as possible. Once a structure’s shape and size are complete it is time to move on to the next robot.

Vacuum Robot
This is the final robot of the MiniBuilder construction process. It uses a vacuum within a suction cup to allow for attachment to the surface of an object. The purpose of this robot is to reinforce the structure which has been printed. To do this it travels up and down the structure repeatedly with two tracks, printing a material almost perpendicular to that of the other layers. This provides substantial support for larger objects.

Working together these Minibuilders are able to produce large scale 3D prints without the need for a large scale 3D printer. Although the technology may not have been perfected, researchers have put in place a stepping stone for a new method of printing buildings and other large object, which we are sure will continue to develop.

What do you think about this new 3D printing system? Could you see large buildings and homes eventually using a technology like this? Let us know in theMinibuilder forum thread at 3DPB.com. Check out the video below, provided by IAAC, showing the Minibuilders in action.
