WHY FIBREX NYLON PA6+GF30
186°C HDT. Chemical Resistant. 6 Colors. PA6 Glass Fiber Nylon.
FibreX™ Nylon PA6+GF30 is 3DXTech’s 30% glass fiber reinforced Nylon 6 filament. PA6 is a semi-crystalline nylon — its 186°C heat deflection temperature (HDT at 0.45 MPa) far exceeds its 70°C glass transition, thanks to the crystalline structure reinforced by glass fiber. That means structurally useful at temperatures that destroy PETG (75°C HDT), ABS (97°C), and even PC (120°C). Paired with PA6’s exceptional chemical resistance to fuels, lubricants, and hydraulic fluids, and available in six color options for finish variety.
186°C HDT — Semi-Crystalline Thermal Advantage
PA6’s crystalline structure enables a 186°C heat deflection temperature with GF30 reinforcement — far above the 70°C Tg. Parts remain structurally functional at temperatures that cause PETG, ABS, and unfilled nylon to soften. Suitable for under-hood automotive, industrial tooling, and hot-process environments.
Fuel, Oil & Chemical Resistance
PA6 delivers excellent resistance to fuels, lubricants, hydraulic fluids, motor oils, and many industrial solvents. Preferred over PA12 in fuel-system and fluid-contact applications. Combined with GF30 structural stiffness, suitable for automotive brackets, fluid-system housings, and tooling exposed to oils.
6 Color Options (More Than CF Variants)
Available in Black, Dark Grey, White, Flat Dark Earth, Tactical Tan, and Gunmetal Silver — more finish variety than carbon fiber FibreX grades. Color selection enables functional part coding, end-use aesthetics, and inspection contrast without secondary finishing operations.
6% Elongation — More Ductile Than CF Grades
At 6% elongation at break, PA6+GF30 is more ductile than CarbonX Nylon 6+CF. Better suited for snap-fits, living hinges, clip-mounting features, and vibration-loaded assemblies where a degree of flex prevents fracture. Hardened nozzle required — GF is abrasive.
PRINTING WITH FIBREX NYLON PA6+GF30
PA6+GF30 — Glass Fiber Nylon 6 with Critical Moisture Control
FibreX Nylon PA6+GF30 requires a hardened steel nozzle — glass fiber is abrasive. Print temperature is 260–280°C with a 60–75°C heated bed. PA6 is highly hygroscopic — more so than PA12 — and must be dried at 80°C for 4 hours before every print session. A heated enclosure is recommended to minimize warping. Drying is non-negotiable: wet PA6 produces poor surface quality, reduced layer adhesion, and inconsistent mechanical properties.
- Extruder Temp 260–280°C — all-metal hot end recommended
- Bed Temp 60–75°C — PEI or garolite build surface
- Chamber Temp Heated enclosure recommended — reduces PA6 warping on larger parts
- Nozzle Hardened steel ≥0.4mm — MANDATORY. Glass fiber is abrasive and will wear brass nozzles.
- Drying 80°C / 4 hr minimum before every print session — PA6 is highly hygroscopic
- ⚠ Moisture Warning PA6 (Nylon 6) is significantly more hygroscopic than PA12 (Nylon 12). Even a few hours of ambient exposure after opening can degrade print quality. Symptoms of wet filament: popping/crackling during extrusion, rough surface texture, bubbling in the melt, and reduced layer adhesion. Always dry before printing and print from a dry box when possible.
THERMAL DATA
186°C HDT — Semi-Crystalline PA6 Outperforms Its Own Tg
PA6+GF30 is semi-crystalline: the 70°C glass transition (Tg) is NOT the structural limit. Crystalline regions maintain load-bearing performance well above Tg, yielding a 186°C HDT at 0.45 MPa. This is the key thermal advantage of glass fiber reinforced PA6 over amorphous polymers. Verified against 3DXTech AmideX PA6-GF30 TDS.
The key thermal number. GF30 reinforcement enables structural performance at 186°C — a temperature that causes PETG (75°C HDT), ABS (97°C), and standard PC (120°C) to fail. Semi-crystalline PA6 maintains stiffness far above its glass transition via crystalline domains locked by glass fiber.
PA6 Tg — the amorphous phase softening point. For semi-crystalline PA6, this is NOT the service limit. The crystalline structure and GF30 reinforcement keep the part rigid well above Tg. HDT (186°C) is the relevant structural design limit for load-bearing applications.
Required before every session. PA6 is among the most hygroscopic engineering nylons. Drying at 80°C for 4 hours removes absorbed moisture that would otherwise cause print defects, reduced layer adhesion, and degraded mechanical properties.
Accessible on a wide range of printers with all-metal or PTFE-lined hot ends rated to at least 280°C. Unlike PEEK or PEI grades, PA6+GF30 does not require a 400°C industrial platform — though a heated enclosure is recommended for larger parts.
CHEMICAL RESISTANCE
PA6 Chemical Resistance: Fuels, Oils, and Hydraulic Fluids
PA6 delivers outstanding resistance to fuels, lubricants, hydraulic fluids, motor oils, and many industrial chemicals — making FibreX™ Nylon PA6+GF30 the preferred nylon for fluid-system components and automotive applications. PA6 has broader fuel and oil resistance than PA12 in many chemical families. Note: PA6 absorbs moisture from the environment and is not suitable for continuous hot-water immersion. Consult the TDS for full chemical compatibility data.
Consult 3DXTech AmideX PA6-GF30 TDS for complete chemical compatibility data. PA6 is susceptible to strong acids and concentrated bases. Not recommended for continuous hot-water immersion or high-humidity structural applications without adequate drying protocol.

WHERE IT WORKS
Where 186°C HDT and Oil/Fuel Resistance Define the Requirement
When the application demands high heat performance above 100°C AND chemical resistance to fuels, lubricants, or industrial fluids — FibreX Nylon PA6+GF30 is the answer. PA6+GF30 fills the gap between standard nylons (which soften under heat) and exotic PEEK grades (which are expensive to print).
Automotive Under-Hood Components
Brackets, clips, housings, and fluid-system components operating near engine heat. 186°C HDT handles under-hood temperatures that destroy PETG and standard nylons. PA6 chemical resistance withstands exposure to fuel, oil, and coolant.
Fluid-System Housings & Connectors
Manifolds, connectors, and housings in contact with hydraulic fluids, lubricants, or fuel. PA6’s excellent hydrocarbon resistance, combined with 4,261 MPa stiffness and 186°C HDT, enables production-ready fluid-contact parts.
Industrial Tooling at Elevated Temperatures
Jigs, fixtures, and end-use structural parts requiring sustained structural performance above 100°C. 186°C HDT with GF30 reinforcement holds tight tolerances in hot industrial process environments without dimensional drift.
Snap-Fits, Clips & Vibration-Loaded Parts
6% elongation makes PA6+GF30 more ductile than CF grades — better for snap-fit features, living hinges, and components that absorb vibration loads without fracturing. Higher ductility than CarbonX Nylon 6+CF.
Color-Coded Functional Parts
Six available colors (Black, Dark Grey, White, Flat Dark Earth, Tactical Tan, Gunmetal Silver) enable part identification by color, end-use aesthetic matching, and assembly guidance without secondary painting or marking operations.
Defense & Industrial Structural Components
Structural brackets, housings, and load-bearing components for defense and industrial programs requiring ISO 9001 certified domestic manufacture, color options for field identification, and proven GF nylon mechanical performance.
MATERIAL CARE
PA6 Is Highly Hygroscopic. A Consistent Drying Protocol Is Non-Negotiable.
PA6 (Nylon 6) absorbs moisture from ambient air significantly faster than PA12 (Nylon 12). A spool left open for even a few hours can absorb enough moisture to degrade print quality. Follow this protocol every session — no exceptions. Wet PA6 produces crackling during extrusion, rough surface texture, and reduced mechanical properties.
Dry Before Every Session
80°C minimum / 4 hours minimum. PA6 absorbs moisture faster than PA12 — no exceptions, even if the spool appears sealed. A filament dryer set to 80°C is the simplest way to ensure consistent results.
Print From the Dryer
For best results, print directly from a heated dry-box or dryer. Ambient humidity will re-absorb into PA6 during extended print runs — especially in humid environments. A dry-box setup eliminates moisture-related print defects.
Store Sealed With Desiccant
Return unused filament to an airtight bag or container with fresh silica gel desiccant immediately after printing. Long-term storage in original sealed packaging with fresh desiccant is recommended. Replace desiccant when it indicates saturation.
Recognize Wet Filament Symptoms
Popping or crackling during extrusion, rough or bubbly surface texture, poor layer adhesion, and stringing are all signs of moisture contamination in PA6. Re-dry for 4+ hours at 80°C and restart. Do not attempt to “print through” wet nylon.
HOW IT COMPARES
FibreX™ Nylon PA6+GF30 vs. Commonly Evaluated Alternatives
Buyers evaluating FibreX Nylon PA6+GF30 typically compare against FibreX Nylon 12+GF30 for an easier-printing nylon GF option, CarbonX Nylon 6+CF for a stiffer CF alternative, and generic glass-filled nylon for a price comparison. PA6+GF30 wins on HDT and chemical resistance.

FREQUENTLY ASKED
FibreX™ Nylon PA6+GF30 — Buyer Questions Answered
What is FibreX™ Nylon PA6+GF30?
FibreX™ Nylon PA6+GF30 is 3DXTech’s 30% chopped glass fiber reinforced PA6 (Nylon 6) filament. Available in six colors (1.75mm), it delivers 4,261 MPa tensile modulus, a 186°C heat deflection temperature, and excellent chemical resistance to fuels, lubricants, and hydraulic fluids. A hardened steel nozzle is mandatory — GF reinforcement is abrasive and will wear brass nozzles. Note: 3DXTech manufactures this as AmideX PA6-GF30 internally; the storefront brand is FibreX.
What temperatures does FibreX™ Nylon PA6+GF30 require?
FibreX™ Nylon PA6+GF30 requires an extruder temperature of 260–280°C and a bed temperature of 60–75°C. A heated enclosure is recommended to minimize PA6 warping on larger parts. Dry at 80°C for 4 hours minimum before every print session — PA6 is highly hygroscopic and moisture degrades print quality and mechanical properties.
Why is the HDT 186°C if the Tg is only 70°C?
PA6 is semi-crystalline. In semi-crystalline polymers, the glass transition (Tg = 70°C) governs only the amorphous phase. Crystalline domains remain intact and load-bearing well above Tg. GF30 reinforcement further extends dimensional stability at elevated temperatures by bridging across crystalline and amorphous regions. The result: 186°C HDT from a nylon with a 70°C Tg — structurally useful at temperatures that destroy amorphous polymers like PETG or ABS.
How does PA6+GF30 compare to PA12+GF30 (Nylon 12)?
PA6+GF30 has a higher HDT (186°C vs. ~155°C for PA12+GF30) and superior chemical resistance to fuels and hydrocarbons. PA12+GF30 is less hygroscopic and slightly easier to print — better for applications where moisture management is a constraint. PA6+GF30 wins for applications demanding maximum thermal performance or fluid-system chemical resistance. Both require hardened nozzles and similar print temperatures.
What applications use FibreX™ Nylon PA6+GF30?
FibreX™ Nylon PA6+GF30 is used in automotive under-hood brackets and housings (near engine heat), fluid-system components in contact with fuel and hydraulic fluids, industrial tooling requiring 186°C+ HDT, snap-fit and clip-mounting features needing ductility (6% elongation), color-coded functional parts for identification, and defense structural components requiring ISO 9001 certified domestic manufacture.
Why does PA6+GF30 need a hardened steel nozzle?
Glass fiber is abrasive. A standard brass nozzle will show measurable wear when printing GF filament — and at 30% loading, the wear rate is significant. Hardened steel, ruby-tipped, or sapphire nozzles all work. 0.4mm minimum diameter is recommended — smaller nozzles are more prone to GF bridging and clogging. This requirement applies to all fiber-filled filaments (both CF and GF grades).
What colors are available and does color affect properties?
FibreX™ Nylon PA6+GF30 is available in six colors: Black, Dark Grey, White, Flat Dark Earth, Tactical Tan, and Gunmetal Silver. Color pigments are cosmetic additives and do not meaningfully affect mechanical or thermal properties. All colors share the same 186°C HDT, 4,261 MPa tensile modulus, and GF30 reinforcement. This makes PA6+GF30 unique among FibreX GF grades — CF variants are black only.
What spool sizes are available and what is the price?
FibreX™ Nylon PA6+GF30 is available in 750g ($56) which ships from stock in all six colors. 2kg is a special-order spool with a minimum order quantity of 10 — contact Rev1 for pricing and lead time. All sizes are 1.75mm.
