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) .
