How 3D printing is helping the green building sector
The need to rethink every aspect of life in the name of sustainability – in line with the objectives of the 2030 Agenda – has pushed the construction sector to find “green” and eco-sustainable production solutions (this topic was presented a few articles ago).
Green building is moving towards this direction: the set of methods for designing and constructing a building in line with the principles of environmental sustainability and reducing negative impacts on the environment.
And, as highlighted in a few articles ago, this reduction of the environmental impact can be accomplished with the use of eco-sustainable, green building materials.
In short, a rethinking of eco-friendly building and sustainable living does not only concern the design of buildings, but also their management. Technological innovation is the protagonist and finds its new developments in 3D printing.
But what is meant by 3D printing? Let’s find out together.
What is 3D printing? It’s all about additive manufacturing.
3D printing is the process that allows you to create three-dimensional physical objects using a particular printer controlled by a computer. It starts with a digital 3D model that is transformed into a physical object by adding the material one layer after another (hence the term additive manufacturing).
Today, this innovative printing system can be counted among the most disruptive technologies of our time, as well as one of the main protagonists of the fourth industrial revolution.
How 3D printing is changing green building
Even green buildings can enjoy the benefits of additive manufacturing: just think of the possibility and greater ease in reproducing models of buildings and entire urban areas.
- Low environmental impact, since the 3D printer allows you to use any type of material, leaving room for the use of recycled materials and materials of natural origin.
- Making components or products in 3D cuts production times in half, as well as being more precise.
- Reduced costs compared to traditional houses, because workers don’t need advanced training and transport costs are reduced to a minimum as materials can be found locally.
To conclude, even though the creation of 3D printed houses is still in the early stages, it is already evident how this technology can improve our society in a sustainable way: just think of all those poor and deserted areas of the world, where, for lack of money, resources, manpower and technology, there are people who need a comfortable home and cannot have one.
Of course, there are many obstacles, but when there is great will there is a way we can make giant steps in a very short time.
