Scientists at Abertay University have found a way, with 3D printing, to study soil without getting their hands dirty. The abundance of life in soils can stagger the mind just as quickly as contemplating the universe considering there is more life in a handful of soil than there are people on earth. The majority of soil is actually full of living organisms like fungi and types of bacteria, not to mention the burrowed creepy-crawlies. To accurately analyze these complex underground ecosystems, scientists often have to disrupt soil too much to get a sample. 3D printing offers a solution that curtails the potential effects by providing a replica of a smaller sample. Scientists at the SIMBIO Centre at Abertay use a mould cast from images of the soil.
With the mould and the computer design, scientists can view complex structures within their sample. The imaging and mould allow the researchers to analyze the points of connection and separation for various organisms. The imaging provides the SIMBIO scientists with a way to study without taking the (soil) systems apart. With the design of the sample, they can view the geometry of the core and assess the methods and interactions between microbes.
Some of the ramifications for the study affect the environment and crop development. By determining how fungi and microbes grow and interact in the geometry of the soil, we can determine the best method to facilitate natural growth.
The interesting and challenging character of soil stems from the influx of physics, chemistry and biology all at play. By using a 3D printed model, the scientists will introduce fungi to the structure and measure growth and interaction. Before, only analysis was possible and after breaking the systems at work. Thanks to 3D printing, the study becomes holistic.
