ProX MATERIAL QUALITY CONTROL (MQC) SYSTEM
The MQC System is designed to be used as the material handling unit for the ProX 500 SLS line of printers . It is responsible for
delivering material to the printer, storing and mixing fresh and used material, and breaking out the SLS parts from the print cake which
is produced by the printer . One MQC System can handle material for up to two printers .
Blended Material Bin:
Material which is a combination of used material and fresh material is stored for production use in
this hopper . The system handles this automatically .
Recyled Material Bin:
Material which has gone through the system is stored here for production use . The used material
is reclaimed through the sifter .
See letter ‘F’ below
.
Fresh Material Input:
Fresh material is loaded at this location . The user must scan the material tag on the container
across the Reader
(See letter ‘I’ below)
to open the doors .
Breakout Controls:
This wheel switch allows the user to turn the sifter on and off .
Reject Chute:
Spent material (as determined by the user) is loaded into the reject chute .
Sifter:
The user removes the parts from the print cake in the breakout area and places the material for reuse into the
sifter . After sifting, the material will be transported to the used material hopper .
Breakout Area:
The print cake is brought here using the
Part Transfer Cart Assembly
.
Thermocouples:
Two temperature gauges for the print cake used to determine whether or not the print cake has cooled
sufficiently to break out the parts.
Nitrogen Cooling Lid:
This lid is placed on top of a filled print cake extraction cylinder to control the cooldown of the print
cake when using nitrogen for cooling .
