FIL X – PA (Nylon) -1.75mm – Natural – 1Kg

A Polyamide (PA) is a Polymer consisting of amides joined by peptide bonds. Polyamides occur naturally, in the form of proteins, and synthetically. Nylon is one of the most common synthetic Polyamides.

Polyamide has been produced in filament form for quite a long time before the advent of 3D printing, this is because it is the plastic used in garden trimmers.

Polyamide is flexible and wear resistant with an excellent strength to flexibility ratio. It is also less brittle and more UV and chemical resistant than PLA or ABS. It also prints with a smooth finish that requires very little post processing.

Polyamide prints will absorb water which makes them unsuitable for some application. On the other hand, this also means that they can absorb some water-based dyes so they are easily coloured. This also means you have to be particularly careful when storing polyamide filaments to prevent them absorbing water.

Polyamide does not have great print bed adhesion and will not adhere to PEI at all. Cardboard or blue painters tape tend to be the best options for good print bed adhesion. A heated bed is usually required, depending on the filament in question. Polyamide is usually printed at around 245°C.

Polyamide is a great all round 3D printing filament as it is strong, durable and prints with a nice finish
