GLOSSARY The Glossary defines terms that describe the ProX 950 and its operations. After the glossary, you will find the Technical Specifications for your ProX 950 . 5 3D Systems, Inc. 3 ProX 950 PRODUCTION PRINTER FEATURES MATERIAL DELIVERY MODULE The Material Delivery Module (MDM) is the device that manages all subsystems related to the print material including printing a part. It can hold up to 935 liters (247 U.S. gal.) of print material. The maximum print volume is 1500 x 750 x 550 mm (59 x 29.5 x 21.7 in.) For more information on the MDM see Material Delivery Module (MDM) on Page 15 . The MDM allows for quick material changes without any material waste/scrap. Not only can you now change material in less than ten minutes, you can also swap the material delivery module (MDM) easily, with no tools required. All components that come into contact with the material are moved with the module itself. One person can remove the MDM and replace it with another active MDM, without having to clean any wet material surface. This new feature significantly reduces material swap time. In addition, you can warm up an MDM offline, enabling you to swap one material delivery module for another that is ready to use. This new handling method ensures that all parts that come into contact with the material during normal operation are a part of the active MDM . Nitrile gloves are required to detach the Zephyr print applicator, especially if there is any material left on the applicator . There are two operating modes for the MDM:

Print Mode In this mode, the MDM is online and connected to the ProX 950 which provides the MDMs power and Input/Output functionality. The ProX 950 monitors and controls the material temperature while connected with the active MDM. When the MDM is online, it can pump and recirculate material. Stand-by Mode In this mode, the MDM is offline and operates independently from the ProX 950. When the MDM is plugged into a standard wall socket the module self-regulates the temperature keeping it stable and at operating temperature. The material can warm effectively in this mode, enabling the user to print a part while warming material for future use, allowing for no down time. MDM Capacity The ProX 950 is the largest commercially available 3D printer, the extra large material delivery module accommodates a print zone of 1500mm x 750mm x 550mm. Refill Container The ProX 950 refill containers incorporates smart cartridge technology that contains information about the material that is in the bottle and the MDM. This information enables the ProX 950 to verify that the user does not use the wrong material, use material incorrectly, or use an empty or expired containers, ensuring the material is safe to use. PRINT APPLICATOR The print applicator system either applies material to, or removes excess material from the part during the printing process as the applicator moves across the material surface. The print applicator system has a Zephyr applicator with four axes of motion: The y-axis moves the applicator from the front to the rear. Other motion systems are utilized to ensure the exact amount of material is deposited, resulting in the high part accuracy produced on this system. The applicator systems liquid level sensor maps the material surface by moving around the material surface. The sensor calibrates the position of the applicator so that it moves perfectly parallel to the material surface, enabling the print to be accurate and precise. The applicator system uses the motion axes that are connected to the applicator, enabling the system to self-

calibrate and permitting a customized setting of the applicator gap, or distance from the applicators bottom to the material surface, for different materials. POLYRAY PRINTHEAD The ProX 950 Polyray Printhead allows for the output of the largest parts quickly and accurately. It does this by operating and seamlessly aligning two separate IPMs (Image Print Modules) during the printing process. The IPMs contain the UV light source, drawing mirrors, power regulator and light source size configurator. 6 3D Systems, Inc. 4 ADDITIONAL DOCUMENTATION The following documents will help you to achieve maximum proficiency with your ProX 950 .

The applicator process combines elevator and applicator movements to apply material to the top of the part so that the next layer can be built. The applicator, which contacts the material, can be removed from the ProX 950. The applicator should be kept with the MDM so that when the material is changed, the applicator remains with the material that it has been in contact with. Note: applicator tabs are delicate . Extra care should be taken to prevent damage to them . If tabs are damaged, the applicator calibration process will not perform properly, resulting in print failures . To install the applicator, do the following:

1 Take applicator off of the applicator rest that is on the MDM. 2 3 Place the applicator onto the two locating pins. Secure applicator with the thumb screws which are present. To remove the applicator, do the reverse of above:

1 Loosen the thumb screws . 2 3 Remove the applicator from the two locating pins. Place applicator onto the applicator rest located on the MDM. 1 3 2 Note: During printing, if the print completes or stops, or if the applicator stalls, the applicator automatically moves back to the home position . PRINT APPLICATOR CLEANING The print applicator will need to be cleaned periodically. Remove the print applicator, wipe print applicator off with a paper towel with some isopropyl alcohol. Be careful not to get any isopropyl alcohol in the material in the MDM. Be sure to wear nitrile gloves when handling print applicator. 37 3D Systems, Inc. PRINT PLATFORM INSTALLATION Verify the MDM is installed in the machine before starting this process. When correctly installed, the print platform sits on the elevator platform mount.
