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 resin spills and drips out through the back of the MDM. If you notice that resin 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 resin 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-print-chamber door and pull the MDM toward you. There are hard stops built into the slides to keep the MDM 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) a full turn. The panel should now slide up and off.

  1. Wearing nitrile gloves, move the resin 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 resin 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 wast material into the can, spray IPA on any visible spots of resin. Continue until all visible resin is gone.
  2. Dry the drip tray with lint-free paper towels.

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

The Printer Drip Tray is designed to contain a large resin spill so that resin does not leak outside of the machine. It has many spill dikes throughout to help keep resin spills in one section of the tray. If there are only drops of resin 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 resin 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 resin 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 Spill 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 resin 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 resin. Continue until all visible resin is gone.
  2. Dry the drip tray with lint-free paper towels.

  1. Reinstall the Printer Drip Tray in the machine. Ensure the bottom of the sensor is flush with the tray.
