Why Choose PA/PET

Performance where it really matters.

Nylon (PA) excels where parts flex repeatedly, wear against other parts, or need toughness. PET adds strong toughness and chemical resistance with easier printability, making both ideal for functional, long-lasting parts.

Excellent Fatigue Resistance

Withstands repeated bending, flexing, and cyclic loads without cracking.

Abrasion Resistant

Holds up against friction, wear, and moving parts.

Chemical Resistant

Performs well with oils, fuels, solvents, and many industrial chemicals.

High Layer Adhesion

Strong, durable parts with reliable interlayer bonding.

Long Flex-Life

Built for parts that need to bend, flex, and keep working over time.

Things to Keep in Mind

Not for every application.

Highly hygroscopic

Must be dried before (and sometimes during) printing, or parts turn weak and stringy.

Prints hot and can warp

Requires high temperatures and an enclosed setup. Larger parts may warp without proper control.

More demanding material

Among the most demanding and highest-cost materials we offer, due to printing requirements.
