EXTEM™AMHH811F filament can resist highest temperatures on the market

The Italian manufacturer Roboze and the chemical company SABIC have unveiled the fruit of their recent collaboration: a new high-temperature 3D printing material, EXTEM™AMHH811F filament. Compatible with Roboze’s ARGO 500 3D printers, designed for production, this amorphous thermoplastic polyimide (IPT) has the highest temperature resistance of its class in the additive manufacturing market. It can withstand continuous operating temperatures of up to 230°C.

In recent years, the additive manufacturing market has seen the development of many industrial applications, made from plastics that are more technical than PLA or ABS. Among these polymers, we find the large family of high-performance thermoplastics such as PEEK, PEKK or ULTEM, which offer properties of interest to the industry in terms of mechanical strength, chemical resistance, dimensional stability and temperature resistance. Some of them can reach heat resistance of up to 260°C. The SABIC and Roboze new amorphous thermoplastic polyimide – EXTEM™AMHH811F – offers unprecedented temperature resistance in this polymer family.

Based on SABIC’s EXTEM resin, Roboze states that it has heat deflection performances of up to 230°C and excellent dimensional stability. Its glass transition temperature should reach 247°C, proof that this TPI offers high rigidity even at high temperatures. Keith Cox, Head of SABIC Operations adds: “To enable customers to print high quality parts for a range of demanding high temperature applications, SABIC and Roboze have worked closely together to optimize printing parameters and secure UL recognition of EXTEM™ parts printed on the ROBOZE solution.” This certification was launched as part of the UL Blue Card program for plastics in additive manufacturing. It is used to check whether the materials are suitable for use in 3D printing and for the user.
