Clean Drip Trays

There are two different drip trays in the printer: MDM Drip Tray and Printer Drip Tray. This section shows how to clean both trays.

MDM Drip Tray

The MDM Drip Tray is designed to channel material spills and drips out through the back of the MDM. If you notice that material is leaking out the back of the MDM from the drip tray, cease printer operation immediately. You must find out if the leak is due to component leakage and contact 3D Systems immediately. For simpler spills, such as incidental material drips from a material changeover, simply wipe the drips away with a paper towel moistened with IPA. For significant leaks, use the following instructions:

  1. Power down the printer by pressing the power button.

  1. Open the lower-build-chamber door and pull the MDM Drawer toward you. There is a hard stop built into the slides to keep the drawer from coming completely out.
  1. Use a T20 screwdriver to remove the bottom two M4 screws (in red, below) on the MDM front panel. Loosen the top two M4 screws (in green, below). The panel should now slide up and off.

  1. Wearing nitrile gloves, move the material tubing up to clear the drip tray, and carefully remove the tray with your other hand.

  1. When carrying the drip tray to your hazardous waste bin, tilt it slightly away from the spout on the far side of the tray, so as not to accidentally pour material out of the spout.

  1. Empty the contents of the MDM Drip Tray into your hazardous waste container, according to all government regulations. Pour slowly from the tray's spout.

  1. While holding the tray above your hazardous waste can, with the spout channeling waste material into the can, use a lint-free paper towel and wipe excess resin into the waste can. Wet the drip tray with IPA and wipe problem spots until entire drip tray is clean. Wipe entire drip tray with an IPA-soaked, lint-free paper towel.
  2. Dry the drip tray with lint-free paper towels. Allow tray to air dry for at least 30 minutes before reinstalling in the MDM.

Your MDM Drip Tray is clean and ready to be reinserted into the printer. Remember to reinstall the MDM front plate before resuming printer operation.

Printer Drip Tray And Leak Sensor

The Printer Drip Tray is designed to contain a large material spill so that material does not leak outside of the machine. If there are only drops of material near the center of this tray, it could indicate a slow leak inside the MDM. Cease printer operation immediately and follow the instructions in the previous section to check the MDM Drip Tray. If there is a significant amount of material in the Printer Drip Tray, it indicates a major leak. Cease printer operation and contact 3D Systems Service immediately. For simpler spills, such as incidental material drips from a material changeover, simply wipe the drips away with a paper towel moistened with IPA. For significant leaks, use the following instructions: drip-tray-out.jpg
  1. Open the Lower-Build Chamber Door and, wearing nitrile gloves, gently remove the Leak Sensor from its bracket, being sure to grab the sensor itself and not the cord. Clean the sensor with a paper towel moistened with IPA.

  1. Carefully pull the Printer Drip Tray out with both hands. When carrying the tray, be sure to keep it level, parallel to the ground so that no material spills over the edges. Empty the contents of the Printer Drip Tray into your hazardous waste container, according to all government regulations. Pour slowly over one corner.

  1. While holding the tray above your hazardous waste can, with the far corner channeling wast material into the can, spray IPA on any visible spots of material. Continue until all visible material is gone. Be sure to also spray the Leak-Sensor Bracket with IPA.
  2. Dry the drip tray with lint-free paper towels.

  1. Reinstall the Printer Drip Tray in the machine and reinstall the leak sensor. Ensure that the bottom of the sensor is flush with the tray and that the light on the sensor turns green.
