Nylon melts at temperatures above 240 °C, which are not suitable for PTFE-lined hot ends. Although some blends of Nylon can melt at low temperatures of 220- 230 °C, these often have weak mechanical characteristics. To get the best results and a high-quality print, you need to use an all-metal hot end that can work at such high temperatures.

Nylon filament readily absorbs moisture from the environment, and it can get wet during the printing process itself. You need to store the filament in dry conditions and away from humid areas. When you’re not using it, a filament storage box with desiccant is an excellent option to store Nylon. If you notice bubbles or weak layer adhesion in your prints, your filament is most likely wet, and you will need to dry it before printing. 

To extract any moisture from the filament, you can dry it in an oven at 160°F – 180°F for 6 to 8 hours. While printing, too, if you print Nylon directly via the storage box, it will minimize the chances of filament absorbing moisture.

Nylon is prone to warping during 3D printing, so an enclosure will help keep it cool and reduce the warping phenomenon. An actively heated print chamber will be ideal for Nylon. But even a heated bed with an enclosure should be enough to minimize the Nylon’s warping.

While an enclosure helps reduce the warping of Nylon filament, using brims and rafts will also be helpful. A raft and brim will provide different print surfaces and prevent the lifting of corners and edges of the 3D print. Additionally, printing Nylon on a garolite surface or a glass bed with a glue stick gives excellent bed adhesion.
