Best Nylon Filament for 3D Printing 2026
Nylon is the toughest, most versatile engineering filament you can print at home — but it's also the most demanding. Moisture sensitivity, warping, and high temperatures make it unforgiving for beginners. When you get it right, nothing beats nylon for functional parts that need strength, flexibility, and heat resistance simultaneously. Here's how the best nylon filaments compare in 2026.
🏆 Quick Answer
Best Overall: Polymaker PA12-CF — reliable, low moisture absorption, stiff CF reinforcement. Community Classic: Taulman 910 — proven toughness, best inter-layer bonding. Best for Bambu: Bambu Lab PA12-CF. Premium: Prusament PA11 CF. Budget: FormFutura TitanX.
Why Choose Nylon — And Why It's Hard
Exceptional Strength
Nylon outperforms PLA, PETG, and even ABS in impact resistance and inter-layer adhesion. It's the go-to material for gears, living hinges, snap-fits, and load-bearing brackets.
Heat & Chemical Resistance
PA12 handles up to ~150°C HDT; PA6 up to ~180°C. Nylon resists oils, fuels, and many solvents — making it ideal for automotive, industrial, and outdoor functional parts.
The Moisture Problem
Nylon absorbs moisture faster than any other common filament. Wet nylon pops, bubbles, loses strength, and produces rough surfaces. You must dry it before every print.
Nylon is a material for makers who have already mastered PLA and PETG. If you're new to printing, get comfortable with those first. When you're ready, nylon opens up a new class of functional parts. For background on the material, see our Nylon material profile.
How to Choose a Nylon Filament: Key Criteria
1. PA12 vs PA6 (the most important decision)
PA12 absorbs much less moisture (0.25% vs 3.5%), warps less, and is easier to print. PA6 has higher heat resistance and tensile strength for demanding engineering applications. For most makers: start with PA12. See the full comparison below.
2. Carbon Fiber or Glass Fiber fill?
CF nylon (e.g. PA12-CF) adds stiffness and reduces warping — but it requires a hardened steel nozzle and reduces impact toughness slightly. Unfilled nylon is more flexible and tougher. Choose CF when you need rigidity; unfilled when you need impact resistance or living hinges.
3. Nozzle temperature range
Most nylons print between 250–285°C. Verify your hotend can reliably hold these temperatures — stock all-metal hotends on E3V3, MK4, and X1C are all capable. PTFE-lined hotends (Creality stock) are a fire risk above 240°C; upgrade before printing nylon.
4. Your drying setup
Without a filament dryer or food dehydrator capable of 70–90°C, nylon printing will be frustrating. This is non-negotiable. See our nylon drying guide for setup options and timing.

PA6 vs PA12: Which Nylon Is Right for You?
PA6 and PA12 are both polyamide nylons, but they have meaningfully different properties for 3D printing. PA12 has become the dominant choice for most desktop FDM applications — here's why, and when PA6 still wins.
| Property | PA6 | PA12 | Winner |
|---|---|---|---|
| Moisture absorption | ~3.5% (very high) | ~0.25% (low) | PA12 ✓ |
| Heat deflection temp (HDT) | ~180°C | ~150°C | PA6 ✓ |
| Tensile strength | ~80 MPa | ~55 MPa | PA6 ✓ |
| Flexibility / impact resistance | High | Good | PA6 ✓ |
| Warping risk | Very high | Low to medium | PA12 ✓ |
| Ease of printing | Difficult | Moderate | PA12 ✓ |
| Enclosure requirement | Mandatory | Recommended | PA12 ✓ |
| Cost | Lower | Slightly higher | PA6 ✓ |
✅ Choose PA12 when:
- • You're new to nylon printing
- • You don't have a fully enclosed printer
- • Dimensional stability matters (humid environments)
- • You need reliable repeated performance
- • Printing CF or GF reinforced nylon
✅ Choose PA6 when:
- • Part operates above 150°C
- • Maximum tensile or impact strength needed
- • Industrial or automotive application
- • You have a fully enclosed, temperature-controlled printer
- • Budget is the primary constraint

Nylon Print Settings: The Numbers That Matter
Nylon is the most setup-intensive common filament. Get these settings right and it prints beautifully. Miss one and you'll fight warping, delamination, or bubbling all session.
| Parameter | Value | Notes |
|---|---|---|
| Print Temperature | 250–285°C | PA12: 260–275°C | PA6: 265–285°C | Start mid-range, adjust for layer adhesion |
| Bed Temperature | 60–80°C | PEI with glue stick or Garolite (G10) recommended — best bed surface for nylon |
| Enclosure Temp | 40–60°C ambient | Required for PA6, strongly recommended for PA12 on large parts |
| Print Speed | 30–50 mm/s | Slow down for nylon — fast speeds cause delamination and stringing |
| Retraction | 1–3mm (DD) / 4–6mm (Bowden) | Too much retraction = jams; too little = stringing. Tune carefully |
| Layer Height | 0.2–0.3mm | Thicker layers improve layer adhesion on nylon — 0.25mm is a good default |
| Cooling Fan | 0–20% | Minimal or no cooling — nylon needs heat to bond layers properly |
| Nozzle Material | Hardened steel (CF nylon) | Brass OK for unfilled nylon; hardened steel mandatory for CF/GF variants |
| Drying | 70–80°C / 6–8h (PA12) | PA6: 80–90°C for 8–12h. Print directly from dryer when possible |
Critical Printing Tips
💧 Always dry nylon — every time, before every print
This is not optional. Even a 30-minute exposure to 60% humidity can degrade print quality enough to cause failures. Dry PA12 at 70–80°C for 6–8 hours; PA6 at 80–90°C for 8–12 hours. A food dehydrator or Bambu filament dryer works well. For the full protocol, see our Nylon Drying Guide.
🏠 Use an enclosure — especially for PA6
An enclosed build volume at 40–60°C reduces warping and improves layer adhesion dramatically. Bambu X1C and P1S have built-in enclosures that make them among the best printers for nylon. On open printers, a cardboard or foam enclosure is better than nothing.
🛏️ Use the right bed surface
Nylon bonds poorly to standard PEI and glass. Best options: Garolite (G10) sheet — the community favorite for nylon adhesion. Alternatively, use PEI with a generous glue stick layer. Some makers use sandpaper-textured PEI with glue. Clean the surface before each print; nylon oil contamination kills adhesion.
🔩 Use a hardened steel nozzle for CF nylon
Carbon fiber and glass fiber fillers are highly abrasive. A standard brass nozzle will wear out within a few hundred grams of CF nylon, leading to inconsistent extrusion and underextrusion. Use a hardened steel nozzle (0.4mm or 0.6mm) — the Bondtech CHT hardened steel and E3D ObXidian are community favorites.
Frequently Asked Questions
What is the best nylon filament for 3D printing in 2026?
Polymaker PA12-CF is the best all-around nylon for most makers — low moisture absorption, good stiffness from CF reinforcement, and reliable extrusion. If you want unfilled nylon with maximum toughness, Taulman 910 is the proven community benchmark. For Bambu printers, Bambu Lab PA12-CF gives you the least friction out of the box.
Is PA12 or PA6 better for 3D printing?
PA12 is better for most desktop printing scenarios. It absorbs far less moisture (0.25% vs 3.5% for PA6), warps less, and is more forgiving to print. PA6 has higher tensile strength and heat resistance — use it only when those specific properties are needed and you have a fully enclosed printer with proper temperature control.
Do I need to dry nylon filament before printing?
Absolutely — every time, without exception. Nylon absorbs moisture faster than any other common filament. Wet nylon produces popping sounds, rough surface finish, poor layer adhesion, and brittle parts. Dry PA12 at 70–80°C for 6–8 hours, PA6 at 80–90°C for 8–12 hours. Print directly from a filament dryer to prevent re-absorption during long prints. See our complete nylon drying guide.
Do I need an enclosure to print nylon?
For PA6: yes, mandatory. For PA12: strongly recommended, especially on parts larger than a few centimeters. An enclosed build volume at 40–60°C ambient reduces warping and dramatically improves layer-to-layer adhesion. The Bambu X1C and P1S with their built-in enclosures are excellent nylon printers. On open-frame machines, even a makeshift cardboard enclosure significantly improves results.
The Bottom Line
Nylon is not a beginner material — but for makers who have put in the time with PLA and PETG, it unlocks a new level of functional part quality. The key to success is setup: dry filament, enclosed printer, correct nozzle, and the right bed surface. Get those four right and nylon prints are surprisingly repeatable.
