Self printed, self healing houses now possible
While it’s one thing to watch these machines create actual physical objects, seemingly out of thin air, from the warehouse to the workshop, it’s the continual flow of concepts we simply never considered that is staggering. Due to an infinite amount of possibilities available in digital design and 3D printing—and a ‘the sky is the limit’ attitude—our world is just on the cusp of changing in so many ways.
Many innovations that will change the way you lead your daily life are still in the proof of concept and preliminary manufacturing stages, but gaining steam—from the way cars are made to how potholes are fixed. From our food to supplements and medications, you should expect many amazing improvements in the future, along with greater affordability.
While construction has been a bit slower to show itself as miraculous from within the 3D printing realm, we are seeing greater progress now there too, especially internationally. Dubai, in the midst of an enormous 3D printing initiative, has unveiled the first 3D printed office building, and in Italy, the first 3D printed village is truly underway. And while it’s predicted that soon many homes will be 3D printed with unprecedented speed and affordability, the US government’s Defense Advanced Research Projects Agency (DARPA) is taking the idea far beyond what most of us have ever considered, continuing on their path in studying 3D technologies.
On a mission to make homes that are the ultimate in affordable and offering self-sustainability, researchers at DARPA are certainly attempting to take things up a notch. Offering materials your contractor probably never offered you, such as bone, skin, bark, and coral, the idea is basically to build living constructions that can fix themselves.
With the Engineered Living Materials (ELM) program, researchers are certainly throwing some futuristic concepts at us. Imagine this:
- Chimneys that self-repair
- Roofs capable of manipulating and controlling airflow
- Driveways that clean up after themselves, absorbing such eyesores as oil stains
And definitely putting a new spin on the smart home, what DARPA researchers see occurring in the homes of the future is intuitive infrastructures that respond to their homes through engineered biology, much like the 3D and 4D printed items we’ve begun reporting on that are able to adapt and change with their environment. Here, advanced construction materials will be morphing to handle issues that crop up in the home environment, with most of them preventing damage to the home and yard, and eliminating a lot of headaches for the homeowner.
“The vision of the ELM program is to grow materials on demand where they are needed,” the program’s manager, Justin Gallivan, said.
“Imagine that instead of shipping finished materials, we can ship precursors and rapidly grow them on site using local resources. And, since the materials will be alive, they will be able to respond to changes in their environment and heal themselves in response to damage.”
The actual, stated mission of the ELM program by the researchers is as follows:
“The Engineered Living Materials (ELM) program will develop tools and methods to enable the engineering of structural features into cellular systems that function as living materials, thereby opening a new design space for construction technology.”
“The ELM program seeks to deliver technologies that will enable the addition of living structural materials into our built environments. Such novel materials would reduce the energy and financial burden associated with the manufacture and transport of materials to construction sites, since they will be able to grow on-site from natural feedstocks. Furthermore, as they will contain elements that are alive, the resulting structures will be endowed with the ability to self-repair and respond appropriately to changes in the environment.”
