With dozens of filament types available, selecting the right material is the most consequential decision in any 3D printing project. PLA, PLA+, PETG, and nylon each occupy distinct positions in the performance spectrum — and understanding where they overlap and differ prevents costly material mismatches. This comparison covers the mechanical, thermal, and practical differences to help you make confident filament choices.

| Price per kg (USD) | $15-25 | $20-35 | $20-30 | $40-80 |
PLA: The Universal Starting Point
PLA is the best entry point into 3D printing for three reasons: it prints flawlessly on nearly any printer, it is affordable, and it produces parts with excellent surface finish. The material shines in visual prototypes, educational models, and decorative prints where appearance matters more than strength. PLA’s limitations — brittleness, low heat resistance, and poor creep resistance — are rarely relevant for display or learning applications.
PLA+: The Practical Upgrade
PLA+ occupies a “sweet spot” between beginner-friendly PLA and more demanding materials. Its improved impact resistance transforms PLA from a brittle display material into a viable solution for many functional applications. The extra 5-15°C on the nozzle is minor, and the printing experience remains nearly as forgiving as standard PLA.
Choose PLA+ when your parts will experience handling, assembly, or occasional impact. The 30-40% price premium pays for itself on the first critical part that does not shatter during testing or shipping.
PETG: The Workhorse Material
PETG offers a significant step up in heat resistance and durability compared to PLA and PLA+. It softens around 75°C — hot enough for automotive interiors, dishwasher-safe parts, and outdoor enclosures in most climates. PETG is considerably tougher than standard PLA and bridges the gap between easy-to-print and engineering-grade materials.
The trade-off is printability. PETG requires a higher bed temperature (70-85°C), is stringier, and is less forgiving with first-layer height. Once dialed in, it produces consistently strong, functional parts at a reasonable price point.
Nylon: The Engineering-Grade Option
Nylon (PA6/PA12) is the top-performing filament in mechanical and thermal capability. It offers up to 80 MPa tensile strength, survives temperatures above 100°C, and delivers exceptional layer adhesion when printed correctly. It is the only material in this comparison suitable for genuine end-use production parts.
Successful nylon printing requires specific hardware: an all-metal hot end, a heated bed capable of 80-100°C, an enclosure to prevent warping, and active filament drying (nylon absorbs moisture so aggressively that it can become unprintable within hours of exposure to ambient air).
For industrial B2B applications — such as production jigs, machine components, and durable prototypes — nylon is the material of choice. Nylon Plastic offers PA6 and PA12 filament with consistent diameter tolerance and batch-tested mechanical properties for professional applications.
Material Selection Decision Guide
| Заявка | Recommended Material | Причина |
|---|---|---|
| Visual prototypes | PLA | Cost-effective, excellent surface finish |
| Snap-fit enclosures | PLA+ | Impact resistance prevents cracking |
| Outdoor brackets | PETG | UV and heat resistance for exterior use |
| Production jigs | Nylon (PA6/PA12) | Maximum durability for repeated use |
| Gears and bearings | Нейлон | Self-lubricating, wear-resistant |
| Automotive interior | PETG or Nylon | Must survive 60-80°C interior temps |
