The Extended Chroma Module (ECM) is designed to enhance the capabilities of the CX-I extruders by expanding their capacity to 16 CX-I extruders by adding four of ECM’s. Each ECM supports up to four CX-I extruders, this allows printing with up to 8 colors or more instead of the usual 4. To achieve this advanced color printing functionality, the ECM can be connected to either the KCM or the ChromaPad systems.
