ProJet x60 Series User Guide ProJet x60 Series Overview
During printing, binder is first applied with a higher saturation to the edges of the part, creating a strong
"shell" for the part exterior. In a color printer, this shell will contain the colors. Next, an infrastructure that
works like strong scaffolding is created for the part walls, which are also built with a higher saturation of
binder for added strength. The remaining interior areas are printed with a lower binder saturation, which
gives the part its stability. See the illustration below.
When the part is finished printing, the user empties the Build Bed of most of the excess Core material
around and on the part by vacuuming with the integrated vacuum system. This "coarse cleaning" returns
the Core to the Feeder for reuse. After coarse cleaning, the part is ready to be removed from the printer
and undergo "fine cleaning". Fine cleaning consists of blowing off the remaining Core material using com-
pressed air and brushing the part to loosen any Core that adheres. Fine cleaning is easily accomplished in
the separate Core Recycling Unit, or in a printer equipped with a Post Processing Unit.
You can evaluate the part as it is, or you can choose to post-process the part with infiltration products to
give it additional strength and durability. With the finished part in your hands, you can start improving or
modifying your design within the same day, and usually within hours.

1.5 Important Terms

Binder - VisiJet PXL liquid binder is dispensed through the HP11 print head and applied to the VisiJet PXL
Core material. The binder saturation value will vary depending on the part geometry. The 3DPrint software
uses a default core and shell saturation value that is suitable for most part geometries.
Build Bed - The area in front of the Feeder where the part is printed. The platform of the Build Bed can be
raised or lowered using the appropriate command on the printer LCD menu. Before each build, the printer
fills the Build Bed with VisiJet PXL Core and then spreads a final layer of Core to ensure the surface of the
Build Bed is completely smooth.
Build Chamber - The interior of the printer that houses the Build Bed, Service Station, the Debris Separa-
tor, the Carriage, the Fast Axis assembly, the Vacuum Hose, and the Feeder.
Carriage - Assembly that houses the Print Head and its Pogo Pin Connectors.
Consumables - VisiJet PXL Core, VisiJet PXL binder, and the infiltrants that are used (wax, salt water,
ColorBond, StrengthMax). All consumables have been developed for the fastest printing speeds and low-
est materials costs.
Debris Separator - Located in the Build Chamber. Its function is to prevent chunks or particles from going
back into the printer Feeder during any vacuuming operation.
