This was true for all tested bacteria strains, which included S. epidermidis, P. aeruginosa, and MRSA, and all tested materials, as 3D printed PEKK significantly outperformed commercially available titanium and PEEK controls.

Key Points: 
  • This was true for all tested bacteria strains, which included S. epidermidis, P. aeruginosa, and MRSA, and all tested materials, as 3D printed PEKK significantly outperformed commercially available titanium and PEEK controls.
  • As expected, the experiment showed greater protein adsorption of lubricin, mucin, and casein on PEKK in comparison to PEEK and titanium controls.
  • This greater protein adsorption was then correlated to greater bacteria inhibition of 3D printed PEKK compared to commercially available PEEK and titanium.
  • This finding is extremely important as it provides objective evidence explaining why OPM's 3D printed PEKK exhibits inherent antibacterial effects.
