Nylon

Nylon is a premium 3D printing material intended for engineering applications. It combines very high strength, toughness, low friction, pliability, chemical resistance, and thermal durability. Depending on the printing parameters, the final part can be made to have some flex, or be more rigid. It comes in a natural translucent white, but can be dyed different colours with acid based dyes.

Nylon

Nylon is a great material for end use parts, machine parts, functional prototypes, and parts that need to support a load.

Material Properties

Please note that these properties are heavily dependant on part geometry and printing parameters. When submitting an order, be sure to indicate how the part will be used so we can help meet your needs!

Stress Strain Curve

This stress strain curve was created with the help of the materials testing lab here at McMaster University in JHE. Tensile tests were performed on samples 3D printed with 2 perimeters, 3 top & bottom layers, and 20% infill. As these results are unique to these parameters, only use the stress strain chart to compare materials. We cannot guarantee that your part will have the same properties.

We use nylon 3D printing filament from Taulman 3D, the industry leader in FDM nylon materials. The following material properties and notes are taken directly from their website.

Notes:

  1. Manufacturer ID is self assigned and used for Production and shipping references.
  2. Based on an average of reported values. Nominally 5C lower with SeeMECNC and E3D HE's due to their structures.
  3. Note on t-glase…If the platform cools faster than the part, then a glass platform may suffer cracks. Tg on Nylon can be missleading due to nylon's structure.
  4. Pyrolysis is basically "Boiling"….Check your thermistor!
  5. Print Bed temperature for nylons is a function of reducing the "shock" from layer to layer. Shock is defined as the time between layers such that the temp diff is at it's greatest.
  6. Small parts in t-glase need a fan on the part being printed due to it's Tg.
  7. Moisture plays a strong part in shrinkage. Less moisture = less shrinkage.
  8. To adhere nylon to nylon, use a soldering iron.
  9. Testing performed by St Louis Testing Laboratories.
    Unit = 5500R Instron with Bluehill Software.
    ASTM D412-0a E2
    5 pc's printed at rated temperature
    Bars are .1314" thick
    1 perimeter
    All surfaces (no fill, just surfaces)
    45 degree surfaces
  10. As natural is not a specific color, we are working on a Pantone equivalent.
  11. Living hinge is using the material flexible properties as a hinge assuming 2000 90 degree transitions.
  12. As nylon will take on water, only air cooling should be used.
