3D print medical devices in high performance polymers with EXT 220 MED

The EXT 220 MED, formerly the Kumovis R1, is an open filament 3D printer designed to enable manufacture of medical devices with implant- and medical-grade polymers like PEEK and Radel® PPSU.

Temperature Management is Key to Excellent Mechanical Properties

The EXT 220 MED is equipped with a global laminar air flow, which allows users to heat the build chamber homogenously up to 250 degrees Celsius. The additional local air flow helps you improve the mechanical properties of your devices. The platform is designed to control temperatures during production. Medical devices produced using thermogenic polymers, like PEEK and Radel® PPSU, are temperature controlled during production resulting in high-quality printed parts.

  • Fully controllable build chamber heating

    Heat up to 250 degrees Celsius, prevent device warping, increase layer adhesion, and adapt build chamber temperature to suit specific polymers

  • Laminar airflow enabling homogenous temperature distribution

    Guarantee reproducibility with no temperature gradient within the build part

  • Adaptive local temperature management

    Adjust local cooling for each strand and layer individually, heat up to further increase layer adhesion, reduce the need for post-processing, and simplify removal of support structures

Make the Build Chamber a Clean Room

With the help of the integrated filter system, the build chamber can be turned into a clean room to avert contamination. What’s more, the 3D printer is “clean room ready” for production in existing sterile environments and meets medical standards.
