AS NEEDED MAINTENANCE

CLEANING THE LIQUEFIER TIPS

The system automatically cleans the tips before and during each part build - using the tip cleaning assembly.

However, occasionally, material may build up on the tips that cannot be removed during the auto-cleaning process. Remove excess material manually using a brass, wooden-handled brush (included in the Startup Kit).

CLEANING THE CABINET

Use a soft cloth moistened with mild soap and water to wipe down the outside of the cabinet. Do not use abrasive or high alkaline cleaners on the system. Vacuum all air vents of dirt and debris that would block airflow through the system.

CLEANING PLASTIC COMPONENTS

Clean the oven door and all plastic components on the outside of the system using mild soap and water.

Commercially available products made for cleaning plastic are also acceptable. Do not use abrasive or high alkaline cleaners on the system. Avoid streaks by rinsing with clear water and then drying with a soft cloth.

In addition to the above noted user maintenance tasks, Stratasys recommends all 900mc systems go through a

1 year PM which addresses lubing and the replacement of wear components and filters, which if not replaced, may contribute to diminished component life. In addition, Stratasys recommends a 6 month PM on systems with serial numbers lower than L0140 AND serial numbers listed L0148 through L0151. The 6 month PM primarily involves lubing of all the moving XYZ axis components.

Please contact Stratasys Customer Support if you are interested in receiving a quote for these services or would like additional information. Failure to adhere to this schedule could lead to reduced life of XYZ components such as lead screws and bearings.

CLEANING THE OVEN DOOR, CAMERA/LAMP, AND TOUCHSCREEN DISPLAY

Commercial glass cleaner can be used on the outer surfaces of the oven door and touchscreen bezel because these items have an anti-scratch coating applied.

Note: Never apply a glass cleaning product to the high temperature glass inside the oven because discoloration may occur at elevated temperatures.

Use only a 50-50 mix of isopropyl alcohol and water to clean the high temperature glass windows of the oven door and camera/lamp assemblies.

Use the following guidelines for cleaning the polycarbonate oven door window insert:

• Do not use abrasives or high alkaline products.

• Do not apply cleaners in direct sunlight or at elevated temperatures.

• Do not use scrapers, squeegees, razor blades or other sharp instruments.

• Do not clean with gasoline, acetone or carbon tetrachloride.

• If scratching should occur, minor abrasions can be removed or minimized using a mild automotive polish.

• The glass on the oven door should only be cleaned with isopropyl alcohol. This prevents the glass from producing a film at high temperatures.

SUPPLEMENTAL INFORMATION

ELECTRICAL PANEL COMPONENTS (GEN 2 ONLY,

SERIAL NUMBER > 1030)

The electrical panel is located in the back of the system and accessed from behind two hinged access panels.

These can be either opened or removed by a service representative when they are servicing the system.

Virtually all system communication, interface and control takes place or originates from within electrical panel of the Fortus 900mc system. The electrical panel is not intended for customer/user access because potentially deadly electrical power sources are present. Safe electrical practices must be followed when performing service within this enclosure.

Electrical panel components include the following:

• Motor Amplifiers

• 120V DC Power Supply (3X)

• Computer

• AC Filters

• 24V DC Power Supply

• AC Distribution Bus

• UPS

• Oven Thermal Breaker

• Heater Solid State Relay

AUXILIARY PANEL (GEN 2 ONLY, SERIAL NUMBER >

1030)

The auxiliary panel is located on the right side of the system and accessed from the access panels. With the

MAC board interface and control, the auxiliary panel provides two primary functions; vacuum generation and air drying. These functions are performed using an external compressed air source (non-lubricated) at 90-120 psi).

Because of the large build area offered by the Fortus 900mc, two separate vacuum zones on the vacuum platen are provided. The zones are identified as the “inner” and “outer” and permit use of either large or small build sheets. Dried air is supplied to the filament feed path of the system making sure that material delivered to the head does not become contaminated by moisture that could cause part quality issues.

Auxiliary Panel Components:

• Relief Valve

• Solenoid Air Valve

• Input Regulator and Filter

• Coalescing Water and Oil Filter

• Input Manifold and Dual Pressure Sensor

• Vacuum Generators

• Air Dryer

• Dry Air Filter

• Output Manifold and Gauges
