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.

This technology has applications in industrial and consumer 3D printing, and manufacturing of parts pertaining to the aerospace, automotive, defense, or space industries.
Features, Benefits, & Advantages:
• Increases the overall strength of 3D printed thermoplastic parts.
• Allows for the rapid diffusive bonding of polymer chains between beads (thus increasing strength), without distorting
or heating the bulk part.
• Improves the isotropic mechanical properties of 3D printed thermoplastic parts.
Proof-of-concept has been completed and successfully tested.
