Term Definition
Vacuum Pump Enable Controller (VPEC) A unit that houses contactors and fused circuits which
control the switching of power to the pump.
ESIO An assembly that provides inputs and outputs to the
system sensors and the VPEC.
Diverter Valve Assembly that diverts vacuum either into the tooling or
vents it to atmosphere.
Flow Controller A manually operated valve that is used to control the
flow rate of the vacuum to the tooling plate.
Tooling Plate The plate that sits on top of the modified tabletop. It
has channels cut into its base to direct the vacuum to
the table tooling.

5.1 SYSTEM OVERVIEW
The High Flow Vacuum system allows the printer to use low-cost flexible tooling with a high flow–
low pressure vacuum capability.
Bespoke board support tooling plates form a vacuum chamber around the perimeter of the product
or carrier. A table-mounted Tooling Plate assembly is secured to the existing rising table. A pump
provides the vacuum pressure. The option to switch the vacuum on or off is provided in software, it
controls the Vacuum Diverter Valve operation. In the ON state the system is placed under vacuum,
in the OFF state the vacuum is diverted to a port that vents the vacuum. The flow controller valve
allows the user to manually set a vacuum flow level by operating a variable aperture. The three op-
erational states are:
●
High flow vacuum OFF
●
High flow vacuum OFF during the Print Stroke
●
High flow vacuum ON
Unless disabled in the program file, the pump runs continuously during printing.
