MATERIAL DELIVERY MODULE (MDM)

The Material Delivery Module (MDM) manages all subsystems related to the print material including printing a part. It can hold
up to 414 liters (109.3 U.S. gal.) of print material. There are three different sizes available which are listed in the section
Capacity" on page 20. The maximum print volume is 650 x 750 x 550 mm (25.6 x 29.5 x 21.7 in).
The MDM allows for quick material changes without any material waste. Not only can you now change material in less than ten
minutes, you can also swap the 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 feature significantly reduces material swap time. In addition, you can warm up an MDM
offline, enabling you to swap one MDM for another that is ready to use.
This handling method ensures that all parts that come into contact with the material during normal operation are a part of the
active MDM.
When the MDM is removed from the printer, make sure to lock the wheel brakes to avoid hazard of any
uncontrolled movement .
For information on installing the MDM, refer to the section
Nitrile gloves are required to detach the print applicator, especially if there is any material left on the
applicator . See the section,
There are two operating modes for the MDM:

Print Mode

In this mode, the MDM is online and connected to the ProX 800 which provides the MDM's power and Input/Output
functionality. The ProX 800 monitors and controls the material temperature while connected with the active MDM. When the
MDM is online, it can pump and recirculate material. The suitable material temperature for printing is 28 °C (+/- 3 °C).

Stand-by Mode

In this mode, the MDM is offline and operates independently from the ProX 800. 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.
To put the MDM in stand-by mode, plug it into a wall outlet with a standard power cord and turn the MDM power switch on. The
MDM will heat the material.
NOTE: We recommend only heating the material up to 24 hours prior to use . Constantly heating the material
when not in use will prematurely age the material .

MDM Capacity

There are three models of MDM:
NAME
MDM 800-50mm
MDM 800-275mm
MDM 800-550mm

Material Container

The ProX 800 material containers incorporate smart cartridge technology that contains information about the material that is
in the container and the MDM. This information prevents use of the wrong material, incorrect material use, or use of empty
or expired containers, ensuring the material is safe to use. For more information, refer to the sections
