Strengths
- Solid strength for everyday parts
- Wear-resistant for moving and rubbing parts
- Flexible and rubber-like
- Layers bond strongly for clean, watertight prints
- Stays flat, very little warping
- Food-safe potential with the right setup
Things to watch
- Soaks up moisture quickly, keep it sealed and dry before printing
- Prone to stringing, tune retraction and keep the filament dry
- Softens in heat, not for hot cars or near heat sources
- Shrinks as it cools, which can affect dimensional accuracy
Color & finish
Neon Orange prints in Orange. It reads as a vivid orange, close to dark orange.
Common uses
Mechanical & Structural
Bushings & bearings

Specialties
SoftFeels velvety, rubbery, or soft to the touch but does not stretch.
Flexible / ElasticStretches and squishes like rubber. High stretch, very soft. Returns to shape. For phone cases, gaskets, soft grips, shock absorption.
UV ReactiveDoes not glow in the dark. Only glows brightly under UV blacklight. The effect is instant and stops when the UV light turns off. Available in bright neon colors (pink, green, yellow, orange). Not 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.
Chemical ResistantResists damage from oils, fuels, acids, industrial chemicals or solvents. For laboratory equipment, fuel system components, or chemical storage.
Low Friction Naturally slippery surface. Low coefficient of friction. For bearings and sliding parts.
Water Resistant / HydrophobicResists absorbing water or moisture from the air. Maintains mechanical properties in humid or wet environments. For marine parts, outdoor components, or wet environment applications.
