Figure 8-1: Balco WaterJet Cleaning Unit
To
clean
a
model
using
this
device,
you
place
it
in
the
chamber,
and
you
manipulate
it
and
the
jet
using
the
built
‐
in,
waterproof
sleeves.
A
pump
turns
ordinary
tap
water
into
a
high
‐
pressure
jet,
and
a
wiper
keeps
the
window
clear.
Removing Support Material with Caustic Soda
Soak
models
in
a
2
‐
percent
solution
of
caustic
soda
(sodium
hydroxide)
to
remove
support
material
from
difficult
‐
to
‐
reach
areas
and
to
give
the
model
a
smooth,
clean
finish.
The
amount
of
time
you
soak
the
model
in
the
solution
depends
on
how
delicate
it
is
and
how
much
support
material
needs
to
be
removed,
but
it
is
typically
between
half
‐
an
‐
hour
and
several
hours.
In
any
case,
you
should
remove
as
much
support
material
as
possible
before
the
caustic
soda
treatment,
and
rinse
the
model
thoroughly
(with
a
water
jet)
afterwards.
Storing Models
Models
are
cured
as
they
are
printed,
making
them
safe
and
stable
for
a
long
time.
However,
proper
storage
conditions
are
necessary
to
prevent
deforming.
•
Keep
printed
models
at
room
temperature
and
in
a
low
‐
humidity
environment.
•
Do
not
expose
models
to
direct
sunlight
and
other
heat
sources.
Use caution when cleaning delicate models with high-pressure water
systems.
WARNING:
Caustic soda may cause chemical burns, scarring and
blindness. Mixing it with water generates heat that could ignite other
materials.Take adequate safety precautions; always use nitrile gloves
when handling caustic soda and models soaked in it.
