• This grade of PEKK is made using the 70/30 PEKK copolymer (PEKK-C), which has higher thermal properties than PEKK-A.
• Substantially easier to print than PEEK
• Continuous Use Temperature (CUT) of 260°C, and higher for short duration
• Glass Transition Temp (Tg) of 162°C (20°C higher than PEEK)
• Melt Temp (Tm) of 335°C  (allows for lower print temps than PEEK)
• Inherent flame resistance (UL94 V-0)
• Low smoke generation for aerospace applications
• Outstanding mechanical, thermal, and chemical resistance
• Excellent resistance to a broad range of chemicals, such as those used in the oil/gas, automotive, aerospace, industrial, and chemical processing industries

‍

• Extruder Temp:  345 - 375°C
• Bed Temp: 120 - 140°C
• Bed Prep: Ultem™ Tape is the ideal build surface, glue stick on clean glass is suitable
• Enclosure temp (if your printer is equipped):  70 - 150°C
• Print Speed:  20-50 mm/s for 0.2mm layer height, faster print speeds as results and experience dictate

Annealing (post crystalizing) 3D Printed PEKK Parts:  Parts printed with PEKK may be annealed after printing to ramp-up the crystallinity in the resin.  This will maximize mechanical, thermal, and chemical resistance properties.  Printed parts will be transparent golden in color and then turn an opaque tan color once annealed (see picture above).  If you do not post-crystallize the PEKK parts, then the maximum use temperature is 150°C.  If you do post-crystallize, then the maximum use temperature is 260°C.  So you can choose which route to go depending on the needs of your part.  

• Step 1:  Place part in an oven and raise the temperature to 160c, allow to remain at that temperature for 30 minutes.  
• Step 2:  Raise the oven temperature to 200c and allow the part to remain their until it turns a uniform tan color.  Timing will depend on the temperature uniformity and circulation of the air inside the oven.  Allow to cool prior to handling part.
