Scientists have been experimenting with 3D printing and carbon nanotubes for a while, and researchers from Polytechnique Montréal recently used 3D printing to combine carbon nanotubes with a thermoplastic polymer, increasing electrical conductivity and creating a material that can monitor liquids in real time. There are several applications for which this technology could be used to great benefit, such as the detection of leaks in oil pipelines.
