What to consider when choosing a 3D printer nozzle

What are the properties of 3D printer nozzles, and what do they mean?
A long time ago the idea of a 3D printer nozzle for a FFF device was quite simple: it was a 0.4mm brass nozzle, hopefully with a thread pattern to match your hot end.
But times have changed and choosing a nozzle is a bit more complex.
Of course, many 3D printer operators don’t choose their 3D printer nozzle at all: they simply use the nozzle that came with the machine. That works, but often creates limitations in materials and possibly can result in the need for a replacement in the future.
The main characteristics of a FFF 3D printer nozzle are:
- Diameter
- Compatibility
- Durability
- Heat Flow
- Wear Resistance
