However, the PEEK or PEKK manufacturing conditions might affect the crystallinity and consequently the characteristics of the resulting parts. In comparison to amorphous materials like 3D printed PEKK, more crystalline materials, like PEEK, typically have higher mechanical, chemical, and thermal properties. Moreover, PEEK&#8217;s extremely strong chemical resistance has helped it get NORSOK M-710 certification for the oil and gas sector. PEEK has a continuous use temperature (CUT) of 260\u00b0C due to its crystallinity, but the amorphous 3D printed PEKK only reaches a CUT of 150\u00b0C when left untreated.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Even though printing PEEK is typically thought to be challenging, Roboze Argo manufacturing methods make it simple. Argo printers effectively manage PEEK&#8217;s shrinkage, ensuring a positioning precision of 10 m. They are equipped with a heated chamber that ensures a homogenous thermal flow and an HVP extruder that is responsible for depositing such viscous filament. The best material quality in terms of mechanical, chemical, and thermal properties is ensured by the high degree of crystallinity of PEEK obtained with Argo printers.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Both PEEK and PEKK have advantages and disadvantages, thus the user and the application must decide which should be employed.<\/p>\n<!-- \/wp:paragraph --><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>What is the difference between PEEK and PEKK?
