Additive manufacturing techniques, where successive layers are laid down additively into the desired shape, are utilized by 3D printers to manufacture thermoplastic parts. These 3D printers can print intricate product designs much faster than regular machining techniques; however, the strength of the final part may be compromised when compared to parts produced through conventional machining methods. 

This technology significantly improves the strength and mechanical properties of 3D printed parts through a facile post-treatment process involving the use of carbon nanotubes (CNTs) and microwave irradiation. This invention eradicates this weakness of 3D-printed parts via a facile post-treatment process.
