Antero 840CN03

A PEKK-based material

Antero™ 840CN03 is a PEKK-based FDM thermoplastic combining the excellent physical and mechanical qualities of PEKK with electrostatic dissipative (ESD) properties. The material is filled 3% by weight with carbon nanotubes.

As a high-performance polymer, Antero 840CN03 exhibits exceptional chemical and wear resistance, ultra-low outgassing properties and consistent ESD performance. ESD values range from 104 – 109 ohms per square inch. This makes the material particularly suitable for space and industrial applications where these qualities are critical.

Produce prototypes and low volume, highly customized parts with consistent ESD (Electrostatic discharge safe) performance that are strong, temperature and chemical resistant, ultra-low outgassing, and with exceptional wear properties.

Fused Deposition Modeling (FDM) Service

Advantages of parts built with a Stratasys FDM 3D Printer

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.

FDM parts are tough enough to be used as advanced conceptual models, functional prototypes, manufacturing tools and production parts.

Meet production demands

Our FDM production machines are as versatile and durable as the parts they produce.

With the largest build envelopes and material capacities in their class, we can provide longer, uninterrupted build times, bigger parts and higher quantities than other additive manufacturing service providers.

Gain new possibilities

TriMech's FDM 3D printing service will help to streamline your business processes from design through manufacturing, reducing costs and eliminating traditional barriers along the way.

Industries we work with are able to cut lead times and costs, we help clients to deliver better products and get to market faster.
