Each Printer has one Material Delivery Module (MDM), which contains a material cartridge and supplies material to the resin tray via a pump and material-delivery tube. When your cartridge is close to being empty, the Controller GUI and Printer GUI will let you know so that you can prepare to install a new material cartridge.
WARNING: The SYSTEM operator is not authorized to modify the MDM configuration, unless specifically authorized by 3d systems to do so. Only a 3D Systems certified service technician is permitted to make such modifications. if the operator attempts such changes, it risks irreparable damage to the system.
Your MDM may have a different layout, depending on the type of material pump and MCO your printer has. Both versions are seen below:
When you open up the MCO Door to expose the Bottle Coupler, as in the Material Changeover procedure, you will also see a Material-Presence Sensor. This sensor detects if material is present in the Pump Delivery Tube.
|A||Eject Button - Press this button to release the material cartridge from the cartridge chute.|
|B||Cartridge Guide - Engages the cartridge Key to ensure the material cartridge is installed in the correct orientation|
|C||Cartridge Chute - The material cartridge is loaded into this area.|
|D||Material Cartridge Coupler - When the material cartridge is fully seated, this coupler attaches the cartridge to the MDM.|
|E||Material Cartridge Chip Reader - This reads the Cartridge Chip attached to the Material Cartridge.|
|F||MDM Handle - Grab the MDM by this handle to pull it out of the Printer and push it back in.|
The MDM slides in and out of the Printer on tracks. It does not come detached from the machine in normal operation. Only 3D Systems Service may remove the MDM from its tracks. Please see the images below, which show the MDM fully closed and fully open.
