The process of printing has advanced by leaps and bounds. It is no longer limited to just printing pictures or documents. Scientists have developed ways for printing three dimensional objects by 3D printing which is also referred as additive manufacture by which objects are printed layer by layer in to a 3 dimensional body.
3D Bio printing of living tissues and organs
3D printing has been employed by the industries since almost three decades, to print parts of machinery. It was used in the industry majorly for printing prototypes or models. But now after great struggle followed by number of researches and a large number of experiments scientists are able to make living tissues by 3D printing.
Research is still under progress to find ways to develop artificial organs such as kidney, heart and liver using this technology. A lot of people die due to failing organs daily if the scientists are successful it would be a huge break through.
BioInk for 3D printing cartilage
A team of researchers at the Wallenberg Wood Science Center, Sweden have developed way to 3D print human cartilage using the BioInk as the manufacturing material. These researchers have been successful in developing a bioInk that is composed of human cells. The material is rather weak and can collapse if printed alone. To overcome this issue the scientist at Wallenberg Wood Science Center mixed the cell solution with polysaccharides and cellulose fibrils which will provide support to the material and prevent it from collapsing when printed in to tissues. By utilizing it they were able to 3D print ear shape body but in an artificial environment.
Experiments on living mice were carried out to ensure that whether the substance could sustain natural environment and its compatibility with living beings. Surprisingly the 3D printed body not just survived on the living host but produced cartilage. This gave the base to produce cartilage for healing damaged cartilage of joint which causes severe pain along with utilizing it for plastic surgeries of nose and ears. The developers are keen to work on their project with plastic surgeons for further developments that may prove beneficial for suffering people.
