Nylon (PA) Filament

Shop nylon and polyamide filament for wear-resistant mechanical parts, tooling and demanding functional components. The range includes unfilled PA6 and PA12, copolyamide, carbon-, glass- and microsphere-filled grades, plus a flame-retardant PA6 option. Select by polymer and reinforcement first, then confirm drying, chamber and nozzle requirements on the product page.

Which nylon grade should you choose?

PA12 Choose unfilled PA12 for wear resistance, flexibility and mechanical parts where an unfilled nylon is preferred. Browse pa12
Reinforced PA12 Choose carbon fibre when maximum stiffness is the priority; choose glass fibre when impact response and some additional flexibility are more important. Browse reinforced pa12
PA6 Choose unfilled PA6 when its mechanical, thermal and chemical-resistance data match the application. Browse pa6
Reinforced PA6 Choose CF for maximum stiffness, GF30 for hard dimensionally stable parts, or GK10 when lower weight and electrical insulation matter. Browse reinforced pa6
Flame-retardant PA6 Choose PA6-FR where documented flame behaviour is required, and verify the exact UL 94 rating and tested thickness in the technical data sheet. Browse flame-retardant pa6
CoPA Choose copolyamide when its balance of strength, toughness and heat resistance fits the application better than a PA6 or PA12 grade. Browse copa

Polyamide absorbs moisture. Dry each spool to its product instructions, keep it dry while printing and reseal it after use. Enclosure and nozzle requirements differ by grade. Filled materials can be abrasive, so follow the exact nozzle guidance.

When another material is a better fit

PCTG Choose PCTG for tough functional parts when lower shrinkage and printing without a heated chamber matter more than nylon wear performance. Compare PCTG PC Choose PC for rigid, impact-resistant parts with high thermal requirements when nylon's flexibility or wear behaviour is not needed. Compare PC PP Choose PP for lightweight clips, handles and snap-fit parts that need more flexibility and lower weight. Compare PP

Nylon (PA) buying questions

Is nylon the same as PA filament?

Nylon is the common name used for a family of polyamides, abbreviated PA. The exact grade matters: PA6, PA12 and CoPA do not have identical print or end-use behaviour.

What is the difference between PA6 and PA12?

They are different polyamide families with different moisture, shrinkage, thermal and mechanical behaviour. Reinforcement can matter as much as the base polymer, so compare the exact technical data rather than treating all nylon as one material.

Why must nylon filament be dried?

Polyamide absorbs moisture. Wet PA can cause stringing, bubbles, nozzle clogging and inconsistent extrusion. Dry to the product's stated cycle and keep the spool dry while printing.

Does nylon need an enclosure?

It depends on the grade and part size. Some grades recommend an enclosure; low-warp or reinforced grades may not. Follow the exact product guidance.

Does reinforced nylon need a hardened nozzle?

Carbon- and glass-filled nylon is abrasive. Manufacturers of filled grades in this range specify a hardened or ruby nozzle; use the exact nozzle requirement for the selected product.

Should I choose glass- or carbon-reinforced PA12?

Choose carbon fibre when maximum stiffness is the priority. Glass-filled PA12 retains more flexibility and can suit variable or impact loading; compare the exact technical data.
