Nylon

Nylon
is extremely robust and will not crack or break the way ABS or
PLA might after some wear and tear. It also will hold up against
heat much better, as anyone who has ever left a PLA print in a hot
car can appreciate.
Flexibility: Nylon offers an incredible degree of flexibility without
breaking in thin-walled prints or very low z height prints that
allows for flexible constructions like straps or buckles that require
bending portions to lock in place.
Photo/chemical resistance: Nylon is UV resistant and much more
resistant to chemical attack than PLA or ABS.
Low coefficient of friction: Nylon is slippery and will work well when
mated parts need to glide along one another or at a hinged joint.
Unlike ABS, nylon is a 100% thermoplastic. It can be re-melted
and used again and again without loosing its bonding properties.
Nylon viscosity and thermoplastic properties require
that it be under a slight constant pressure during the
print. This pressure is controlled by the extrusion rate.
Nylon is hygroscopic and will absorb water from humid air and it's
storage environment. As the material enters the heater block, it
creates a seal with the added pressure of new material forced in
by the extruder. The temperature at the seal is just at or slightly
above boiling, so as the water steams, it tends to escape via the
nozzle.
Don't use high speeds for infilling objects when printing nylon, the
layers might get disjointed.
