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 PET CF Filament
Four things engineers check before standardizing on a carbon-fiber structural filament.
High strength & stiffness
87 MPa tensile strength and a 6025 MPa tensile modulus — parts carry real mechanical load and resist bending where unfilled filaments would yield or flex.
Dimensionally stable, low warp
Carbon fiber cuts thermal contraction, so large and precise parts hold tolerance across the whole build — the reason it suits jigs, fixtures, and tooling.
±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.
Heat- and creep-resistant
The stiff carbon matrix resists creep and holds an 80°C heat-deflection temperature — parts keep their shape under sustained load and moderate heat, where PLA-CF would soften.
How we ship it
Every spool of CreatBot PET CF Filament leaves Gardena, CA the same way.
Print profile confirmed
Nozzle and bed temperatures verified on a CreatBot Peek-300 high-temperature machine before the spool is listed — not copied from a generic spec sheet.
Sealed with desiccant
Vacuum-bagged with the original desiccant pack so the spool is dry on arrival — carbon-fiber PET prints best bone-dry.
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 an all-metal, high-temperature hotend rated to 320°C and a hardened steel nozzle (carbon fiber is abrasive to brass); a heated bed to 80°C and an enclosure give the best results. This spool’s profile is validated on a CreatBot Peek-300. Full mechanical and thermal property values (tested to ISO 527 and ISO 178) are listed in the Specifications tab below.
Recommended print settings
| Parameter | Recommended value |
|---|---|
| Nozzle temperature | 300°C – 330°C |
| Build plate temperature | 70°C – 90°C |
| Chamber / enclosure | Recommended |
| Print speed | 40 – 45 mm/s |
| Cooling fan | Low |
| Nozzle type | Hardened steel (required — abrasive) |

Storage & handling
Store CreatBot PET CF Filament in a cool, dry place inside its original sealed bag with the desiccant. Carbon-fiber PET absorbs moisture — dry it before printing and use a dry box for long-term storage or humid environments, or moisture shows up as stringing, rough surfaces, and weaker layers.
