General Operation Principal
All pellet head extruders from Massive Dimension operate on a similar principle, with four main
functions. These functions all have to work together in unison to have a successful print. Since
all customers movement systems are different, care will need to be taken into account during
integration.
1. Pellet Feeding - This covers the feeding of pellets from the storage bin to the pellet
head feed throat, where the feed tube enters the extrusion screw section. The Massive
Dimension Pellet Head 2 (MDPH2) can extrude powders to 1/8in diameter pellets.
Issues with feeding material will cause inconsistent output.
2. Screw - Extrusion and screw speed are controlled by the movement controller, supplied
by the customer and depended on the customers movement setup. The MDPH2 motor is
setup to have a torque limit so the screw cannot be over torqued. The screw is
removable by taking off the nozzle. The drive motor uses step and direction
input signals
or Quadrature A/B
.
3. Nozzle - With the MDPH2 nozzles sizes can range from 1mm up to 5mm. The larger the
nozzle size the slower the print speed with the same volume output rate.
4. Movement System - Customer movement systems such as robotic arms or XYZ
systems need to be sturdy and large enough to move the pellet head around. The
MDPH2 in stock configuration weights 8.39kg (18 pounds) .

Mounting Unit
The MDPH2 has a four hole bolt pattern outlined in the drawing below. Four ¼-20 bolts are
provided with the pellet head for mounting.
General Setup
Setup of the MDPH2 is highly dependent on the end users setup. The MDPH2 is designed to be
a retrofitted on customer pre-existing movement systems. Slicing and printing are also
inherently dependent on the movement system setup and will not always be the same setup or
process for printing. The following steps are to help customers mount and setup the motor for
the first time.
Step 1: Mount MDPH2 onto movement system using all four mount holes
Step 2: Wire in controls to your movement system and check all electrical connections are
secure. See wire diagram on following pages.
Step 3: Unscrew and remove nozzle.
Step 4: Remove feed screw
Step 5: Follow the “CLEARPATH QUICK SETUP” from page 8 to 21. This will setup the motor
for the first run. Click Here for Clearpath Manual

Step 6: Once “Auto-Tune” is complete you reinstall the feed screw and nozzle.
Wiring Setup / Diagram
Note: The pellet head will come pre-wired with either 110VAC OR 220VAC. It is not a dual
voltage system.
Care and Maintenance
The MDPH2 is designed to need minimal maintenance. Care should be taken to make sure the
nozzles and system as a whole is fully warmed up before any printing extrusion takes place.
~ Always empty the screw by running the system out of pellets.
~ The screw can be removed and manually cleaned if needed. This is not always required
Warranty
The MDPH2 comes with a 1 year warranty on all parts. Contact us for more details.
