MDM MAINTENANCE
The following general maintenance procedures provided must be accomplished to help maintain high part yield and to reduce the
printer down time.
When changing material cartridges, material may be present in the MDM holder after the cartridge is removed. If a large pool of material
is present (bottom is submerged and walls of the cartridge holder are reached), do not place a clean material cartridge into the holder.
The holder will require cleaning before inserting a new cartridge.
CAUTION: The MDM cartridge receptacle and material will be warm; avoid touching the sides of the holder during the
cleaning process. Wear heat resistant gloves and goggles.
Cleaning MDM Cartridge Receptacle
1. Insert a lint free cloth to absorb the material in the MDM receptacle.
2. Using a long tool, such as tongs; remove the saturated cloth from the receptacle and place in a waste bag. Continue to clean the
receptacle until all material is removed.
3. After the receptacle is clean, ensure there is no debris or lint left inside of receptacle.
4. Dispose of waste material according to local rules and regulations.
Cleaning the MDM Drawer
Using Isopropyl Alcohol and a lint free cloth, dampen cloth with the alcohol and clean around the cartridge holders’ surfaces.
NOTE: Do not clean cartridge receptacles when the 3D printer system is warm. Allow cartridge receptacles to cool
before cleaning the interior of receptacles.
Cleaning Metal Surfaces
1. Do not remove any outer panels when cleaning the printer. Panels must only be removed by qualied 3D Systems Technical
Support Representatives.
2. Remove dust from outer surfaces of printer by wiping with a clean, dry, lint-free cloth.
3. Remove dirt and grease from printer outer surface by spraying all-purpose cleaner on a clean cloth and gently wiping it down.
CAUTION: Use only non-abrasive, alcohol-free cleaners to clean surfaces. Do not use all-purpose cleaners containing
petroleum-based polishing agents such as liquid wax. Spray cleaner on cloth, not on surface. Do not use cleaning
solvents on build chamber window, doing so can damage the protective UV coating.
4. Gently wipe dirt and part material residue from operator control panel using an ammonia-based glass cleaner on a clean, lint-free
cloth.
5. Remove print platform before cleaning the operator panel. This will prevent the printer from initiating any actions if controls are
accidently pressed.
Cleaning Polycarbonate Top Door
CAUTION: Do not use cleaners such has Windex and paper towels to clean polycarbonate surfaces. Use only a non-
abrasive cleaner and a chem wipe or a lint free cloth. Using anything else will scratch the polycarbonate surface.
Cleaning the User Touchscreen
• Spray a water-based solvent such as Simple Green onto a lint-free soft cloth; do not wipe with a dry cloth or spray cleaner
directly onto touchscreen.
• Gently wipe the touchscreen to remove debris.
Do Not Use:
• A dry cloth on the touchscreen*
• Any cleaning products that contain acetone, MEK or alcohol
• Any abrasive cleaning products
• Using these cleaning products can damage the touch screen.
NOTE: Before cleaning, the 3D printer system must be idle to avoid aborting a build.
