3DXTech PA (Nylon) FIBREX™ Nylon PA6+GF30 Flat Dark Earth Summary
This filament is demanding to print. Worth watching: it can be prone to warping and very moisture-sensitive.
Print characteristics
Layer adhesion ExceptionalBed adhesion Requires Special PrepBridging & overhang FairSpeed sensitivity HighWarping HighShrinkage 0.8-2.0 %Stringing ModerateOozing ModerateOdor Moderate
Strengths
- Solid strength for everyday parts
- Resists oils, solvents, and chemicals
- Wear-resistant for moving and rubbing parts
- A little give without being floppy
- Layers bond strongly for clean, watertight prints
- Food-safe potential with the right setup
Things to watch
- Prone to warping, use a heated bed and ideally an enclosure
- Extremely thirsty, keep it sealed with desiccant and dry it right before printing
- Softens in heat, not for hot cars or near heat sources
- Shrinks as it cools, which can affect dimensional accuracy
- Fussy about bed adhesion, use a brim, glue, or a textured plate
Color & finish
A solid Flat Dark Earth filament. It reads as a brown, close to saddle brown.
Finishing
Machinable
Specialties
Glass FiberContains chopped glass fibers in a base polymer. Increases toughness, impact resistance, and heat deflection. Available in multiple colors (unlike carbon fiber). Highly abrasive.
Tough / Impact ResistantEngineered to resist breaking, cracking, or shattering under impact. Unlike standard PLA, which snaps, this flexes slightly before breaking. Ideal for parts that get dropped, bumped, or stressed.
Wear ResistantResists surface wear from friction and sliding. Good for gears, bushings, conveyor parts, or any component that rubs against other surfaces.
High StrengthResists bending or pulling apart under heavy load. Very stiff.
Chemical ResistantResists damage from oils, fuels, acids, industrial chemicals or solvents. For laboratory equipment, fuel system components, or chemical storage.
Heat ResistantWithstands elevated temperatures (hot car, warm electronics) without deforming. Printable on standard printers. HDT ~80-120°C.
Low Friction Naturally slippery surface. Low coefficient of friction. For bearings and sliding parts.
