What your process engineer actually checks
Tight diameter, dry, jam-free
Every spool ships with a datasheet covering diameter tolerance, moisture, and a validated print profile for the systems we sell, so feeds stay consistent and parts hold dimension. Load the profile and print.
A materials engineer on the line
Questions on diameter tolerance, moisture, layer adhesion, or warping? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.

Why engineers choose CreatBot Ultra PA GF Filament
Four things engineers check before standardizing on a glass-fiber nylon.
High strength & stiffness
88 MPa tensile and 141 MPa flexural strength with a 4852 MPa flexural modulus — rigid, strong parts for structural and load-bearing use.
Heat-resistant to 135°C HDT
A heat-deflection temperature up to 135°C and a 147°C glass transition keep parts stable in hot service, well beyond unfilled nylon.
±0.02mm diameter tolerance
Tight, consistent diameter means steady extrusion — no mid-print under-extrusion from a loose spot or clogs from a tight one.
Tougher than carbon fiber
Glass fiber reinforces without the brittleness of carbon — parts absorb more impact before failing, a better balance when stiffness and toughness both matter. Glass is abrasive; run a hardened steel nozzle.
How we ship it
Every spool of CreatBot Ultra PA GF Filament leaves Gardena, CA the same way.
Print profile confirmed
Nozzle and bed temperatures verified on a CreatBot F430 before the spool is listed — not copied from a generic spec sheet.
Sealed with desiccant
Vacuum-bagged with the original desiccant pack — critical for glass-fiber nylon, which absorbs moisture readily.
Ships from L.A. stock
In stock at our Gardena facility — 1–2 business day dispatch, datasheet included in the box.
Print compatibility
Requires an FDM/FFF printer with a nozzle rated to 300°C and a hardened steel nozzle (glass fiber is abrasive to brass); an enclosure improves layer strength on larger parts. Nylon is strongly hygroscopic — dry the spool before printing. Full mechanical and thermal property values (tested to ISO 527, ISO 178, ISO 75, and ISO 1183) are listed in the Specifications tab below.
Recommended print settings
| Parameter | Recommended value |
|---|---|
| Nozzle temperature | 290°C – 310°C |
| Build plate temperature | 70°C – 90°C |
| Chamber / enclosure | Recommended |
| Print speed | 40 – 45 mm/s |
| Cooling fan | Off or low |
| Nozzle type | Hardened steel (required — abrasive) |

Typical applications
Where engineering and production teams run CreatBot Ultra PA GF Filament.
Storage & handling
Store CreatBot Ultra PA GF Filament sealed with the desiccant, and dry it before every print — glass-fiber nylon absorbs moisture readily and prints rough and weak when wet. Use a dry box during printing, especially in humid environments.
