3DXTech ThermaX™ PEKK | 3D Printing Filament | 1.75 mm (0.5Kg) | Black

ThermaX PEKK-A 3D Printer Filament

ThermaX PEKK-A (PolyEtherKetoneKetone) is made using Arkema Kepstan® PEKK and is one of the highest-performance polymers in plastics business. A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. It is also not only substantially easier to print than PEEK, its one of the easiest ultra-polymers to 3D print period. Developed in partnership with Arkema, a leading supplier of ultra-performance materials.

Benefits of ThermaX™ PEKK-A Include:

High thermal properties with a CUT of 260°C, Tg of 162°C, and a Tm of 335°C

Substantially easier to 3D print than PEEK

Wide processing window from 345-375°C

Inherently flame resistant (UL94 V-0)

Low smoke generation

Outstanding mechanical, thermal, and chemical resistances

Recommended Print Settings:

Extruder: 345-375°C

Bed Temp: 120-140°C

Bed Prep: Nano Polymer Adhesive or 3DXTECH Polyimide Tape

Heated Chamber: Recommended, heated to 70-150°C if at all possible

Supports: ThermaX™ break-away HTS High Temp Support works ideal for complex, high-temp materials just like this

Drying Instructions: 120°C for 4 hours

Stress Relieving 3D Printed Parts:

Parts printed with PEKK may be stress relieved after printing to reduce printed-induced stresses and increase the mechanical properties, dimensional stability, and chemical resistance of the printed part. This process does not anneal or induce crystallinity in PEKK-A since this is a mostly amorphous version of PEKK. If your intention is to anneal and induce crystallinity, then we suggest using our ThermaX™ PEKK-C filament that is made out of the 70/30 PEKK Copolymer.
