4 Beginner Tips for Using Nylon 3D Printing Filaments


What do you need to work with nylon 3D printing filaments? Besides a 3D printer, you need special tools like a palette knife, a filament dryer or dry box, a deburring tool, and your filament of choice. As a beginner, you may struggle using nylon 3D printing filaments, and we want to improve the experience by providing four tips for you to use while 3D printing.

Get To Know Your 3D Printer

Your 3D printer creates objects from digital blueprints. The entire process works in layers, and the fiber you use for those layers can determine the quality of your product.

The instructor’s manual offers a more in-depth explanation of how all the controls work, how to insert your filament, and what you need to know about temperatures. However, it doesn’t mean you can use any filament. Some filaments require different 3D printer models.

The best printing technologies to use on nylon filaments include:

  • Multi-jet fusion (MJF)
  • Selective laser sintering (SLS)
  • Fused deposition modeling (FDM)

Learn the Temperatures for the Hot End and Print Bed

Print speed and settings can impact your entire creation process. Although not all 3D printer models support nylon, some models do. Usually, they will have a button to press if it supports the fiber. You need to know two sets of temperatures before printing anything: hot end and print bed temperatures.

When using the hot end, ensure the temperatures are between 240 and 260 degrees Celsius. Don’t go too low or high; you risk burning or not completely melting the fiber. For your first time, start at 245 degrees Celsius. This helps maintain the speed because the temperature increases the faster you print. Ensure you use a metal hot end before printing nylon, as it won’t stick because it doesn’t contain plastic parts.

For the print bed, a surface such as glass or garolite is ideal for getting your first layer to stick. Heating the print bed to around 70 degrees Celsius is a good starting point. Keep the cooling fan low or off to maintain warmth.

Learn Your Finishing Settings

These settings differ from filament to filament, so when working with nylon glass fiber, you’re going to use very fine sandpaper to smooth out the layer lines. Even after creating with nylon, it still attracts moisture, so apply epoxy after printing to protect the surface.

Understand the Properties of Nylon Filaments

Nylon is an excellent filament for 3D printing. It’s super light, flexible, and works well with other materials, like fabric and spray paint. However, the drawback is that it absorbs moisture fast, so you can’t leave spools sitting out for too long.

Here are the properties of nylon:

  • Creating thinner walls increases flexibility.
  • Making thicker walls enhances stability.
  • The material has high durability but no solubility.
  • It’s hygroscopic. Simply put, it absorbs moisture from the air.
  • It has heat and impact resistance.

As a beginner, nylon is a difficult material to work with, but by following the tips on working with 3D printing filament for the first time, your experience improves.
