- PLA (Polylactic Acid)
- Tensile Strength: High (\(\approx 50\text{ MPa}\))
- Flexibility: Low (Brittle)
- Max Temp: Low (\(50^{\circ }\text{C}\) to \(55^{\circ }\text{C}\))
- Best For: Indoor use only. Ideal for aesthetic models, display pieces, and low-stress parts.
- PETG (Polyethylene Terephthalate Glycol)
- Tensile Strength: Medium-High (\(\approx 40\text{ MPa}\))
- Flexibility: Medium (Slight give)
- Max Temp: Medium (\(75^{\circ }\text{C}\) to \(80^{\circ }\text{C}\))
- Best For: Indoor & light outdoor use. Good for functional mechanical brackets and moisture-exposed parts.
- ABS (Acrylonitrile Butadiene Styrene)
- Tensile Strength: Medium (\(\approx 35\text{ MPa}\))
- Flexibility: Medium (Impact resistant)
- Max Temp: High heat (\(95^{\circ }\text{C}\) to \(100^{\circ }\text{C}\))
- Best For: Indoor use (unless painted/coated). Ideal for enclosed electronic housings and heat-adjacent parts.
- ASA (Acrylonitrile Styrene Acrylate)
- Tensile Strength: Medium (\(\approx 40\text{ MPa}\))
- Flexibility: Medium (Tough)
- Max Temp: High heat (\(95^{\circ }\text{C}\) to \(100^{\circ }\text{C}\))
- Best For: Extreme outdoor use. Unmatched UV and weather resistance for outdoor housings and marine fixtures.
- TPU (Thermoplastic Polyurethane)
- Tensile Strength: Low to Medium (\(\approx 25\text{ MPa}\))
- Flexibility: Ultra-High flexible (Rubber-like)
- Max Temp: Medium (\(60^{\circ }\text{C}\) to \(80^{\circ }\text{C}\))
- Best For: Indoor & outdoor use. Perfect for gaskets, seals, and vibration-dampening pads.
- Nylon (Polyamide)
- Tensile Strength: High (\(\approx 60\text{ MPa}\))
- Flexibility: Highly flexible in thin sections (High impact toughness)
- Max Temp: High heat (\(100^{\circ }\text{C}\) to \(120^{\circ }\text{C}\))
- Best For: Indoor use (absorbs outdoor humidity). Excellent for gears, hinges, and friction bearings.
- PC (Polycarbonate)
- Tensile Strength: Ultra-High (\(\approx 70\text{ MPa}\))
- Flexibility: Medium-Low (Rigid)
- Max Temp: Extreme high heat (\(110^{\circ }\text{C}\) to \(130^{\circ }\text{C}\))
- Best For: Indoor & specialized outdoor use. Built for high-stress structural components.
- Carbon Fiber Filled (e.g., PA-CF)
- Tensile Strength: Extremely High (\(\approx 75\text{ + MPa}\))
- Flexibility: Lowest (Extremely rigid)
- Max Temp: High heat (Varies by base resin, often \(120^\circ\text{C}+\))
- Best For: Indoor & structural outdoor use. Lightweight drone frames and structural jigs.
Quick Selection Cheat Sheet
- Best for Outdoors: ASA (UV-resistant, retains color and strength in sunlight)
- Best for High Heat: PC (Highest temperature resistance before deformation)
- Best for Flexibility: TPU (Bends, stretches, and returns to its original shape)
