Nylon filament is an odorless blended filament with brilliant strength with a glossy appearance.
Nylon filament has great layer adhesion, fusing each layer together well. The main benefit of this filament is its flexibility and flexural properties. The use of “zip ties” is almost exclusively made from nylon for this very reason. It can be flexible when printed finely and yet can withstand a lot of strength for that thickness. A printed object with greater thickness will however not share the same flexibility however will enjoy a significantly higher level of pull strength. Nylon has some flexible memory, allowing it to return to almost the same position after it is bent (with a greater yield than ABS or PETG). The printed filament allows for greater flexibility for deformation whilst holding layers firmly. For example, a screw can drive into an appropriately sized pilot hole of a printed object without causing the layers to split.
Once printed the filament can withstand higher temperatures compared to PLA, PETG, and ABS without deforming.
The printed object has a glossy finish however can be prone to warping and stringing. Achieving great results requires refinement of your printer settings. Please read the last section for printing tips.
This filament retains a great amount of impact resistance largely due to its relative softness. The shock impact absorption coupled with its strong layer adhesion allows the printed object to remain intact even when exposed to high impact force.
Nylon filament is very hygroscopic (more than PLA) and it is critical that it is kept in the resealable bag provided to ensure it continues to print well. The filament when produced was packed and sealed immediately to remain unexposed to moisture from the air. When the filament absorbs too much moisture from the surrounding air, the print quality will reduce, and the predictability of results diminish.
Nylon can be carefully dehydrated at 65 degrees Celsius for 4-5 hours. Ovens are often poorly calibrated so please remember to do a test sample of 5 meters first and where possible use an external oven thermometer (these are available at kitchenware shops).
Some helpful printing tips;
- Always print in a well-ventilated room.
- Part cooling is not necessary.
- Print using an enclosure
- First layer adhesion is key to stop the part lifting and failing. Minimize this by adjusting some of the following;
- Lower your z height
- increasing the first layer height and/or width
- use glue on the bed
- Stringing can be a challenge so you should adjust your retraction settings (print retraction spikes) and consider “Avoid crossing outline for travel movements” in Slicers like Simply 3D.
