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

.
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 MDM’s 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 system’s 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
applicator’s 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 IPM’s (Image Print Modules) during the printing process. The IPM’s contain the UV light
source, drawing mirrors, power regulator and light source size configurator.
