PEKK NATURAL – 92 in³ (1510 cc)
High-Performance PEKK Filament — 92 in³ (1510cc) Fortus® Canister Format
PEKK is an ultra-high-performance thermoplastic selected for demanding thermal and chemical environments. This Fortus®-class PEKK is configured for the 92 in³ (1510cc) metal canister workflow, engineered around the fundamentals that drive repeatability in high-temperature production printing:
1.795 mm nominal diameter, disciplined drying, and sealed Mylar packaging.
Cross-reference intent: Stratasys® Antero™ 800NA (PEKK), Fortus Plus 92ci (355-02500). OEM identifiers are used for identification only.
Overview
NEXT 3DP PEKK is a Fortus®-class, high-temperature material designed for users who need extreme performance and are willing to pay for it. In practice, successful PEKK printing comes down to workflow control: stable feeding, stable extrusion, and moisture discipline across long builds.
- Format: 92 in³ (1510cc) metal canister
- Diameter: 1.795 mm nominal (Fortus class)
- Workflow: dried prior to packaging + sealed Mylar moisture control
- Documentation: COA / CoC + lot traceability (program dependent)
- Cross-reference: Antero™ 800NA 92ci (355-02500) identification context
Practical takeaway PEKK is unforgiving. Control dryness + dimensional stability and the printer behaves predictably.

Specs that matter in Fortus® high-temperature printing
High-temperature polymers are moisture-sensitive and Fortus® builds are long — so the practical drivers are feed stability and moisture control: correct nominal diameter (1.795 mm), controlled ovality, disciplined drying, and packaging that stays dry until use.
Workflow control factors
- Fortus® nominal diameter: 1.795 mm
- Diameter & ovality control for stable feed
- Dried prior to packaging (moisture discipline)
- Sealed Mylar packaging to preserve dryness until use
- High-temp build discipline: consistent handling + storage
Documentation & traceability
- Certificate of Analysis (COA) (typical)
- Certificate of Conformance (CoC) (typical)
- Lot traceability for repeat builds and controlled workflows
- Additional documentation may be available (program / application dependent)

PEKK FAQ (Fortus®)
What does “92ci” mean for Fortus® material pricing?
92ci (92 cubic inches) is the standard Fortus® reference format used to compare material costs consistently. Use the cost calculator to convert part volume into cost-per-part.
Does PEKK need drying?
Yes. PEKK is moisture-sensitive. Dryness and moisture-controlled packaging reduce variability and support repeatable extrusion behavior on long builds.
Is this the same as Stratasys® Antero™ 800NA?
This product is a Fortus®-class PEKK option. The Antero™ 800NA identifier (355-02500) is provided for cross-reference / identification context only. OEM names are used for identification only.
Which EEPROM do I need?
EEPROM selection is printer-model dependent (Classic vs Plus, and system type). Contact us with your machine model and we’ll match the correct option.
How do I estimate cost per part?
Use the Fortus Material Cost Calculator to convert your part volume into cost-per-part using 92ci reference format pricing.
