What do I need to print Nylon filament?

Most stock machines are not able to print nylon filament right out of the box. You will need the following parts in order to print nylon on an Ender 3
1. All metal heatbreak
2. Firmware update to enable higher temperatures at the nozzle (300C)
3. 3D Printer Enclosure
4. PrintDry machine (the filament will need to be dried constantly, even while being used (while its
printing – filament in the PrintDry, feeding through a tube to the extruder)

Think you pretty much have it covered. I don’t think you’d need to update the firmware, I’m pretty sure the Ender 3 has a Max temp of 280°C, and you shouldn’t need more than 250-260 for Nylon.
