THE
CHALLENGE
|
|
HP Multi Jet Fusion (MJF) technology is
helping HP streamline processes throughout
its supply chain and replace traditional
manufacturing methods. One example is a tool
in HP’s printhead manufacturing
line—a drill extraction
shoe.
The nozzles of HP printheads are manufactured
with a laser-cutting process, which uses
water to prevent overheating of the laser and
the silicon plates. The drill extraction shoe
is used during cutting to remove the silicon
sludge and water that continuously appear,
enabling a more efficient laser-drilling
process.

CNC Machine assembly vs Multi Jet Fusion topology optimised part
|
|
|
As shown in the image, the original CNC
Machined tool (on the left) is made of
seven sub-parts, most of which are
mechanized from an aluminum block. The HP
MJF redesigned part (as shown on the
right in the image) has been consolidated
into a single part.

RESULTS
|
Using HP Multi Jet Fusion technology to produce
this part helped enable:
|
|
|
-
The watertight properties required for
manufacturing aids that contain
pressurized fluids, without needing
to post-process or coat the
parts.
-
-
The optimization of the design
to reduce turbulence in the part using
finite element analysis. The shape of
the end of the pipe has been modified
to optimize flow during the section
transition.
-
-
Cost reduction of 95% compared
with the original part.
-
-
Weight reduction of 90% compared
with the original part due to topology
optimization and material
reduction.
-
-
Lead-time reduction: CNC
Machining required three to five days
of processing, while HP MJF completes
the same task in 24 hours.
-
-
Assembly reduction by
consolidating seven sub-parts into one
single part.
