ESD PEKK

A PEKK-based material

ESD PEKK (electrostatic dissipative polyetherketoneketone) is a thermoplastic with static dissipative properties for applications where a static charge can damage products or impair performance.

It has excellent chemical resistance and favorable mechanical and thermal properties, making it appropriate for demanding applications that require resistance to electrostatic discharge.

Fused Deposition Modeling (FDM) Technology

Advantages of 3D printing ESD PEKK with a Stratasys FDM Machine

Tough long-lasting parts

FDM technology works with engineering-grade thermoplastics to build strong, long-lasting and dimensionally stable parts with the best accuracy and repeatability of any 3D printing technology. ESD PEKK parts are tough enough to be used as advanced conceptual models, functional prototypes, manufacturing tools and production parts.

Meet production demands

FDM systems are as versatile and durable as the parts they produce. Advanced FDM 3D Printers boast the largest build envelopes and material capacities in their class, delivering longer, uninterrupted build times, bigger parts and higher quantities than other additive manufacturing systems, delivering high throughput, duty cycles and utilization rates.

Gain new possibilities

FDM 3D Printers streamline processes from design through manufacturing, reducing costs and eliminating traditional barriers along the way. Industries can cut lead times and costs, products turn out better and get to market faster.
