Comparison of PMMA vs. Nylon (PA-12, PA-6, PA-66, and Blends) for 3D Printing

Comparison of PMMA vs. Nylon (PA-12, PA-6, PA-66, and Blends) for 3D Printing

PMMA (Polymethyl Methacrylate) and Nylon filaments each have unique properties that make them suitable for different applications. This comparison highlights key differences in mechanical strength, heat resistance, chemical resistance, and ease of printing.

1. Mechanical Properties

Property PMMA Nylon PA-12 Nylon PA-6 Nylon PA-66 Nylon Blends (PA-CF/PA-GF)
Strength High Moderate High Very High Very High
Toughness Brittle (low impact strength) High (impact-resistant) Moderate Low Moderate to Low
Flexibility Rigid High Moderate Low Low
Abrasion Resistance Moderate High Very High Very High Extremely High

2. Heat Resistance

Property PMMA Nylon PA-12 Nylon PA-6 Nylon PA-66 Nylon Blends
Heat Deflection Temp (HDT) ~80–100°C ~100°C ~120°C ~150°C ~150°C or higher

3. Chemical Resistance

Property PMMA Nylon PA-12 Nylon PA-6 Nylon PA-66 Nylon Blends (PA-CF/PA-GF)
Chemical Resistance Poor (sensitive to solvents, acids) Moderate Moderate to High High High

4. Water Absorption and Dimensional Stability

Property PMMA Nylon PA-12 Nylon PA-6 Nylon PA-66 Nylon Blends (PA-CF/PA-GF)
Water Absorption Very Low Low High Very High Low to Moderate
Dimensional Stability Excellent Good Poor (affected by humidity) Poor (affected by humidity) Good

5. Transparency and Aesthetic Properties

Property PMMA Nylon PA-12 Nylon PA-6 Nylon PA-66 Nylon Blends (PA-CF/PA-GF)
Transparency Fully Transparent Opaque Opaque Opaque Opaque
Surface Finish Glossy and smooth Matte or semi-matte Matte Matte Matte

6. Ease of Printing

Property PMMA Nylon PA-12 Nylon PA-6 Nylon PA-66 Nylon Blends (PA-CF/PA-GF)
Ease of Printing Difficult (warping, adhesion issues) Easier Difficult Very Difficult Moderate
Print Temp. (°C) ~240–260°C ~240–260°C ~250–270°C ~260–280°C ~250–280°C

7. Applications

Material Typical Applications
PMMA Optical lenses, light covers, display cases, decorative parts
Nylon PA-12 Gears, hinges, medical devices, flexible functional parts
Nylon PA-6 Automotive parts, industrial components, durable mechanical parts
Nylon PA-66 Engine components, high-stress industrial parts, high-temperature applications
Nylon Blends Lightweight structural parts, drones, high-performance gears, aerospace components

Conclusion

PMMA is best for clarity and aesthetic applications, while Nylons are more suited for high-strength, high-temperature, and wear-resistant applications. Nylon PA-66 and PA-CF/PA-GF blends are ideal for industrial and mechanical parts, whereas PA-12 offers better flexibility and moisture resistance.
