Product Overview:The EXT 220 MED, formerly known as Kumovis R1, is the only extrusion platform with an integrated cleanroom. It is validated by leading medical device manufacturers and hospitals worldwide. This filament-based extrusion technology enables 3D printing of implants and instruments using high-performance polymers, including PEEK and Radel® PPSU. The platform features an integrated cleanroom and temperature control to ensure high-quality production.Optimized for cleanroom operationFully controllable build chamber heatingValidated to meet ASTM F2026 standardsExcellent accuracy through delta kinematicsLaminar airflow enables homogeneous temperature distributionAdaptive local temperature managementApplications:CraniomaxillofacialSkull implantsMaxillofacial onlaysOrthopedicsBone platesSpinal cagesPPSU instruments made from Radel®Suture anchorsBenefits:Eight high-performance medical-grade polymersTemperature management ensures excellent mechanical propertiesCleanroom-capable build chamberMonitor and document your processes with real-time dataHomogeneous build chamber temperature up to 250°CTechnical Specifications:Manufacturing technology: Fused Layer Manufacturing (FLM)Machine dimensions: 823 x 985 x 1950 mmBuild volume: Ø 180 x 150 mmManufacturing accuracy: 100/100/100 μmLayer thickness: 50–400 μmPrint speed: 100–3500 mm/minTemperature Management:The EXT 220 MED is equipped with a global laminar airflow system, allowing users to heat the build chamber homogeneously up to 250°C. Additional local airflow improves the mechanical properties of the devices. The platform is designed to control temperatures during production, enabling high-quality 3D printing of medical products from thermogenic polymers such as PEEK and Radel® PPSU.Cleanroom Capability:With the integrated filtration system, the build chamber can be transformed into a cleanroom to avoid contamination. The 3D printer itself is cleanroom-capable, allowing production in existing sterile environments and meeting medical standards.Integrate the EXT 220 MED platform into standard medical production environmentsSupport for passing medical qualification processes (IQ, OQ, PQ)Use the exhaust hood to connect the printer to your cleanroom's exhaust systemFiltration System:Keeps particles out and prevents contaminationMeets ISO Class 7 cleanroom requirements according to DIN EN ISO 14644Advanced Contamination Protection:Eliminate the risk of contamination of filament and end-use partsSimplify cleaning and maintenance with smart design features like touch-to-open hingesProcess Monitoring and Quality Assurance:In addition to monitoring all relevant process parameters, the industrial-grade control system and software used in the EXT 220 MED enable process analysis and documentation, even in highly regulated industries.Example Applications:Craniomaxillofacial ImplantsMaterial: PEEKPatient-specific skull and orbital plates are 3D printed with a complete design-to-delivery workflow.
