3D printers are able to create complex and functional forms using less material than traditional manufacturing and building methods. They aim to significantly reduce building costs by using a combination of scale economies and some improvements in printing machinery.
New form of building from 3D printers
3D printing system is an emerging technology, capable of generating three-dimensional solid physical bodies by layer upon layer of a given material addition. Thus, structures with absolute freedom without the need to use any type of mold or conventional process are created.
Printers consist of two telescopic arms connected by a transverse beam which houses the printhead. These arms are moved horizontally by guides and vertically by the crane of each arm. A special mixture of quick drying concrete comes directly from the cement, which is deposited by layers in certain areas according to the prototype created digitally through a design program.
Actual benefits in the market
The advantages offered by 3D printing are really diverse, as economic and environmental, as social ecological and efficiency, compared to traditional building:
- Ecological: 3D printed houses can be built with organic, eco-friendly materials. Moreover, some house 3D printers use solar energy and generate low CO2 emissions.
- Social: House 3D printers can build affordable houses using earth materials, being of great aid for people in poverty-stricken regions.
- Economical scaling: House 3D printing reduces certain building costs. For example, the cost for 1 square meter of wall using traditional construction methods is approximately $75, whereas with the Apis Cor house 3D printer it is only $27.
- Efficient: Since the materials needed to 3D print a house are 3D printed on demand, the machines produce less waste. In addition, it is possible to recycle construction materials. Therefore, the machines do not produce waste, since the materials are managed accurately. In addition, it is possible to recycle materials from previous construction.
