Product Overview:The EXT 220 MED, formerly Kumovis R1, is the only extrusion platform featuring an integrated sterile environment and is validated by leading hospitals and medical device manufacturers worldwide. It uses filament-based extrusion technology to enable 3D printing of implants and instruments with high-performance polymers such as PEEK and Radel® PPSU. It is the only platform with an integrated cleanroom and temperature controls to enable the production of high-quality devices.Optimized for operation in sterile environmentsFully controllable print chamber heating up to 250°CValidated to meet ASTM F2026 standardsExcellent accuracy thanks to delta kinematicsLaminar airflow for homogeneous temperature distributionAdaptive local temperature managementKey Features:Prints medical devices in high-performance polymersRapid and reproducible printing for a wide range of applicationsValidated by leading hospitals and device manufacturersOpen filament 3D printer for medical and implant-grade polymersTemperature Management:The EXT 220 MED is equipped with global laminar airflow, allowing users to heat the print chamber homogeneously up to 250°C. Additional local airflow improves the mechanical properties of devices. The platform is designed to control temperatures during production to enable high-quality 3D-printed medical devices made with thermogenic polymers like PEEK and Radel® PPSU.Fully controllable print chamber heating: Prevents device warping, increases layer adhesion, and adapts chamber temperature for specific polymers.Laminar airflow: Ensures reproducibility without temperature gradients within the printed part.Adaptive local temperature management: Adjust local cooling for each strand and layer, increase temperature for better layer adhesion, reduce post-processing, and simplify support removal.Sterile Environment:With the integrated filter system, the print chamber can be converted into a sterile environment to prevent contamination. The 3D printer is ready for production in existing sterile environments and meets medical standards.Integrate the EXT 220 MED platform into standard medical production environments.Support for medical qualification process approvals (IQ, OQ, PQ).Use the extractor hood to connect the printer to your sterilized environment's air outlet.Filtration and Contamination Prevention:Includes a filter system: Keeps particles out and prevents contamination. Meets ISO Class 7 cleanroom requirements according to DIN EN ISO 14644.Advanced contamination prevention: Eliminates the risk of filament and final part contamination. Simplifies cleaning and maintenance with smart design, such as one-touch opening hinges.Process Monitoring and Quality Assurance:In addition to monitoring all relevant process parameters, the industrial-grade software and control system used in the EXT 220 MED make process analysis and documentation feasible even in highly regulated industries.Application Examples:Cranio-maxillofacial ImplantsMaterial: ATISBARPatient-specific cranial and orbital plates are 3D printed using a complete workflow from design to delivery.
