Best nylon filament

Nylon makes the toughest parts a consumer printer can produce and it is ruined by moisture faster than any other common material. Every decision about nylon is downstream of that one fact.

Published drying temperatures and times. Prusa Research and Overture disagree on several materials; both figures are shown rather than averaged. A dash means that manufacturer does not publish a figure for that material. Where they differ, the lower temperature for longer is the safer starting point.

Moisture is the entire story

Nylon is the most hygroscopic filament in common use. It absorbs water out of ordinary indoor air fast enough to matter within hours, not days. A spool left out overnight can print visibly worse the next morning than it did the previous evening.

Wet nylon does not merely look bad. The water flashes to steam in the melt zone, which produces bubbling, voids inside the extrusion and a part that is dramatically weaker than the datasheet suggests. A wet nylon part is frequently weaker than a dry PETG part, which makes the whole exercise pointless.

The published drying figures, and the trap

Prusa publish drying below 90 C for polyamide, with 90 C for six hours for the carbon-filled PA11 grade Prusa Research Prusa Research. Overture publish 95 C for seven hours Overture.

Read those numbers against the dryer you own. Many popular consumer filament dryers top out at 55 to 70 C, which is fine for PLA and PETG and simply cannot reach nylon's published figures. This is the most common way people buy the wrong dryer: the spool capacity is advertised prominently and the maximum temperature is in the specification list. Our dryer roundup sorts on that column deliberately.

Printing it

Prusa publish 240 to 285 C at the nozzle and 70 to 115 C at the bed for polyamide, with an enclosure recommended Prusa Research.

  1. Print from a heated dry box if you can, not from a spool sitting on top of the printer. On a long print, a spool that started dry will not finish dry in an ordinary room.
  2. Enclosure closed. Nylon warps, and it is stiff enough when it does that it pulls plates rather than releasing.
  3. Adhesion needs a plan. Nylon does not stick to PEI well. A glue stick as a bonding layer, or a dedicated adhesive, is the usual answer.
  4. Hardened nozzle for filled grades. Carbon-filled nylon abrades brass quickly E3D.

What nylon actually buys you

What it does not buy is stiffness. Unfilled nylon is noticeably more flexible than PLA. If you want a rigid part, that is what the carbon-filled grades are for — the fiber restores stiffness that the base polymer does not have.

Every pick, in detail

01

Polymaker PolyMide PA6-CF

Polymaker

Genuine mechanical parts · 8.4/10 our fit score

A functional 3D printed part in a dark engineering filament (illustrative photograph of the product type)

Illustrative photo of the product type, not this exact item.

A genuine engineering material with genuine engineering requirements: a hardened nozzle, an enclosure, and a dryer you actually use.

Published specifications for Polymaker PolyMide PA6-CF
Nozzle240-285 C (PA range) Prusa Research
Bed70-115 C Prusa Research
DryingAt least 4 h below 90 C Prusa Research
Nozzle materialHardened required — carbon fiber abrades brass E3D

What it does well

  • Carbon fiber loading makes it dimensionally stable in a way unfilled nylon is not
  • Polymaker publish a full data sheet including drying guidance

What it does not

  • Prusa's polyamide page notes improper storage lets nylon absorb water "weighing up to 10% of filament weight"
  • Destroys a brass nozzle quickly; E3D document substantial wear on a new brass nozzle after 250 g of carbon-filled filament
02

Overture Easy Nylon

Overture

A first nylon · 8.0/10 our fit score

A functional 3D printed part in a dark engineering filament (illustrative photograph of the product type)

Illustrative photo of the product type, not this exact item.

Nylon tuned to print at temperatures an ordinary hotend can reach. Still nylon: dry it or do not bother.

Published specifications for Overture Easy Nylon
Nozzle240-285 C (PA range) Prusa Research
Drying95 C / 7 h (Easy PA guidance) Overture
EnclosureRecommended Prusa Research

What it does well

  • Overture publish a drying temperature and time for this exact product
  • Prints below the 285 C Prusa cite as typical for polyamide, which keeps it inside more stock hotends

What it does not

  • Prusa note polyamides "emit a strong odor with potentially dangerous ultrafine particles" and call ventilation or an enclosure a must
  • Absorbs moisture in hours once opened, not days
03

Creality Space Pi X4

Creality

Reaching nylon drying temperatures · 8.6/10 our fit score

A filament spool sitting inside a heated drying chamber (illustrative photograph of the product type)

Illustrative photo of the product type, not this exact item.

The only mainstream consumer dryer here that reaches the temperature nylon actually needs. That single number is the whole argument for it.

Published specifications for Creality Space Pi X4
Temperature range45-85 C Creality
Capacity4 spools; diameter <= 200 mm, width <= 150 mm Creality
Rated power360 W Creality
Drying time range1-48 h Creality

What it does well

  • 85 C clears Prusa's published 80 C for ASA and 85 C for polycarbonate, which a 70 C box cannot
  • Creality publish the exact temperature range, spool limits and rated power

What it does not

  • Creality's own page recommends drying thoroughly before printing rather than feeding straight from the box
  • 360 W is the highest draw in this list; the running cost is not trivial if you dry weekly
04

COSORI Food Dehydrator

COSORI

Capacity on a budget · 7.2/10 our fit score

A filament spool sitting inside a heated drying chamber (illustrative photograph of the product type)

Illustrative photo of the product type, not this exact item.

The cheapest route to real capacity, if you can live without a humidity readout and are willing to pull the trays out.

Published specifications for COSORI Food Dehydrator
Typical rangeAbout 35-75 C on consumer models
CapacitySeveral spools with the trays removed

What it does well

  • Costs less per spool of capacity than any purpose-built dryer here
  • Airflow across a large chamber is genuinely good, which is most of what drying is

What it does not

  • No humidity sensor, so you are drying on a timer and hoping
  • Food-dehydrator thermostats are calibrated for food, not for the 45-50 C ceiling PLA needs — verify with your own thermometer before trusting the dial

Common questions

How dry does nylon need to be?

Dry at the point of printing and staying dry throughout. Prusa publish drying below 90 C for polyamide and Overture publish 95 C for seven hours. On long prints, feed from a heated dry box rather than a spool sitting in room air.

Can my filament dryer handle nylon?

Check its maximum temperature against the published figures. Many consumer dryers top out at 55 to 70 C, which covers PLA and PETG but falls short of nylon's published drying temperatures.

Is nylon stronger than PETG?

When dry, substantially tougher under repeated load and impact, and better at sliding wear. When wet, frequently worse than PETG. The moisture state matters more than the material choice.
