Hot nanotubes help strengthen 3D printed thermoplastics in novel welding process

A team of researchers from Texas A&M University has developed a novel method for improving the strength of 3D printed thermoplastic parts. By coating filaments with multi-walled carbon nanotubes (MWCNTs) and then exposing them to microwaves, the team found that it was able to improve a printed part’s strength by as much as 275%. As 3D printing becomes more accessible and versatile, being used at home, in offices, and on factory floors, there are some notable challenges that persist with the technology. For instance, fused deposition modeling (FDM) 3D printing, which uses a heated nozzle to extrude melted layers […]
