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 s tep and direction input signals

or Q uadrature A/B .

3. Nozzle - W ith 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 - C ustomer 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) .

Page 3 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.
Page 4 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.
Page 5 Wiring Setup / Diagram Note: T he pellet head will come pre-wired with either 110VAC O R 220VAC. It is not a dual voltage system.
Page 6 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.
