The increasing demand for repair of cracking bridges, building, and roads and also the escalating need for sustainable infrastructure are the challenges the construction industry are facing. The biggest demand in the construction industry is concrete but it is found to have a large carbon footprint, high energy expenditure, and high wastage. Recently, researchers have found a sustainable way to produce ceramic using local soil and a 3D printer to form a load-bearing structure. The impact on the environment is the major drawback of the construction industry. Thus, to overcome this issue the researchers believe additive manufacturing or building structures layer by layer using a 3D printer to help renovate the construction industry and also to reduce waste and lower carbon footprint.
The layer by layer construction is found to be not only cheap but also responsible in controlling carbon emissions. The positive prospective of additive manufacturing for building structures can outdo the traditionally used adobe sourced concrete that has a negative impact on the environment. In the new findings, the researchers show how soil from our backyards could help potentially replace the traditional concretes. The use of soil will reduce the transportation and manufacturing cost plus no damage to the environment. The additive manufacturing with soil is guaranteed to be useful in creating settlements on Mars or Moon.
Soil consists of three layers: organic top layer, clay in middle, and hard bedrock in the ending. The clay is what the researchers are investing on. The researchers used additive to bind and tailor the soil layers which was lastly extruded using 3D printer. As the soil varies depending on the location, the aim is to create a toolkit to change any soil type to a printable building material. Furthermore, the zippering of the microscopic layers of soil showed the soil blocks to stand strong and load bear. Lastly, the recycling potential and environmental-friendly nature of these 3D printed structures will help gain a better picture of the feasible and highly functional local soil.
