Scientists create living ink for 3D printing

Scientists used Escherichia coli – Escherichia coli to create 3D printer ink. The work began by modifying bacteria to produce living nanofibers. The researchers then linked the fibers and added other ingredients to make living ink. Scientists have even been able to use ink to print 3D objects. One was a material that released azurine, an anti-cancer agent, when stimulated with certain chemicals.

It is noted that microbes can be forced to create copies of themselves – the ink can literally grow in a jar. Scientists also say the technique can be used to print renewable building materials that can self-repair.
