🧪 Material Properties
- Strong and impact-resistant: Much tougher than PLA.
- Durable: Good for functional parts and mechanical stress.
- Lightweight: Common in automotive and consumer products.
- Slightly flexible: Better than PLA, not as flexible as TPU.
🔧 Printing Characteristics
- Print temperature: 230–260°C.
- Heated bed required: 90–110°C to prevent warping.
- Warping is common: Needs an enclosed print chamber or draft-free environment.
- Strong odor when printing: Ventilation is recommended.
- Poor bed adhesion: Needs adhesives (glue stick, ABS slurry, or PEI sheets).
🧱 Mechanical Properties
- High impact strength: Withstands drops and force.
- Good heat resistance: Glass transition temperature ~105°C.
- Can be post-processed: Easily sanded, drilled, and smoothed with acetone vapor.
- Less brittle than PLA: More ductile under stress.
🌡️ Environmental Resistance
- Moderate weather resistance: Degrades under prolonged UV exposure.
- Moisture-sensitive during printing: Should be kept dry.
- Stable in dry indoor environments.
✅ Common Applications
- Automotive parts
- Enclosures and housings
- LEGO bricks
- Functional prototypes
- Snap-fit parts
- Tools and fixtures
