While nylon is traditionally moisture sensitive, our hydrophobic 3D printer filament addresses the issue by slowing down moisture absorption to help the filament stay as dry as possible. Our hydrophobic filament also goes one step further to minimize the effects of moisture on the print outcome. You still need special consideration, though, to guarantee the best results. Contact us for more information or read below for additional details.

Hydrophobic Nylon has very little warping, making printing a breeze. While Hydrophobic Nylon has drastic improvements over standard Nylons, some measures must still be taken to limit moisture uptake, as it will eventually begin to affect printing. Nylon materials inherently take up moisture from the surrounding atmosphere due to the nature of their chemistry. When most polymers are extruded with high moisture content, the chains in the polymer will break. When this happens, you may notice a change in viscosity and melt strength of the melted polymer. An obvious sign of your nylon being too wet is popping noises as the material is extruded, the moisture in the material vaporizing. All nylon materials are shipped in vacuum-sealed bags to prevent moisture uptake during shipping and storage.

Technical Specification

• Recommended nozzle temperature: 265-290 °C
• Recommended bed temperature: 50 °C
• Adheres to a variety of build surfaces (glass, Garolite, PEI, etc.)
• Nylon is moisture sensitive; measures should be taken to keep the filament dry
• Recommended drying temperature: 120 °C
• Generally, slower speeds, larger nozzles and layers are recommended as a starting point

Tips When Printing With Nylon Filament

Nylon prints will stick to blue painter’s tape. Because Nylon adheres to cellulose surfaces poplar wood can be used as a bed. Some users have used cardboard or hardboard (not to be confused with hardwood). Nylon also sticks extremely well to machinable garolite, but that may be hard to come by. Users have also said that using a glue stick on a glass bed works well. PVA glues (think of Elmer’s white glue all) can also be diluted and applied on with a sponge head. Please use in a well ventilated area or in a closed ventilated system.

Nylon filament absorbs a lot of moisture when left out in the open. Please bake the Nylon filament in the oven at 170°F for 3-6 hours just before printing to remove moisture. For detailed context, visit the link.

• Print speeds : 18 mm/s first layer, then 28mm/s – 34mm/s
• Heated bed of 110°C helps combat Nylon’s warp
• No cooling fans
• Only use in well ventilated areas
• Store dry when not in use, absorbs moisture
