ULTEM™ 9085 for Stratasys® Fortus® — Specs, Test Results & 92ci Pricing
Need a Fortus®-class ULTEM™ 9085 option without the closed-system markup? NEXT 3DP ULTEM™ 9085 is produced from SABIC ULTEM™ 9085 PEI resin and engineered around the workflow fundamentals that drive repeatability in high-temperature Fortus® environments: 1.795 mm nominal diameter, disciplined drying, moisture-managed packaging, and lot-traceable documentation. This page summarizes the workflow priorities plus a direct side-by-side comparison against Stratasys® ULTEM™ 9085 using ASTM test data.
Why NEXT 3DP ULTEM™ 9085 is Fortus®-ready
In Fortus® production printing, ULTEM™ 9085 success is driven by repeatable material behavior under elevated chamber conditions: stable feeding, stable extrusion, predictable shrink/warp behavior, and moisture discipline. The objective is simple — deliver the same functional PEI performance and workflow reliability without premium closed-ecosystem pricing.
Specs that matter in Fortus® high-temperature printing
PEI is 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 filament diameter: 1.795 mm
- Diameter and ovality control for stable feed
- Dried prior to packaging (PEI moisture discipline)
- Molecular sieve moisture control
- Sealed packaging format (moisture-managed)
Documentation & traceability
- Certificate of analysis (COA)
- Certificate of conformance (CoC)
- Lot traceability for repeat builds and controlled workflows
- Additional documentation may be available (program / application dependent)

ULTEM™ 9085 FAQ (Fortus®)
What filament diameter does Stratasys® Fortus® use for ULTEM™ 9085?
Fortus®-class materials are commonly supplied at a nominal filament diameter of 1.795 mm. In production workflows, diameter and ovality control support stable feeding and repeatable extrusion.
Does ULTEM™ 9085 (PEI) need drying?
Yes. PEI is moisture-sensitive, and long high-temperature builds amplify the impact of moisture on extrusion stability and surface consistency. Drying discipline plus moisture-managed packaging helps keep results repeatable.
What does “92ci” mean for Fortus® pricing?
92ci means 92 cubic inches (about 1510 cc). Fortus® materials are often compared in this standard reference format so you can estimate cost per part consistently.
How do I estimate cost per part?
