2. Rapid
prototyping
• is
a
machine
that
used
to
create
a
model
that
designed
by
using
3D
computer
aided
design
(CAD)
data.
• The
first
machine
of
rapid
prototyping
hit
the
markets
in
the
late
1980s.
• in
its
earlier
days
was
applied
to
produc=on
of
models
and
prototype
parts.
But
nowadays
with
the
advancement
in
technology,
rapid
prototyping
is
used
widely
for
many
applica=ons.

3. Rapid
Prototyping
machine
used
in
Jewelry
There
are
many
companies
out
there
that
developed
Rp
machine
for
jewelry
fabrica=on.
However,
I
will
specifically
talk
about
two
most
common
brands
and
types
that
use
in
the
jewelry
field
these
days.
I’m
not
including
the
CNC
machine
here
because
in
my
opinion
the
machine
does
not
work
fast
enough
to
use
the
word
‘rapid’!
2
types
of
the
RP
machine
in
focus…
•3D
prin=ng
from
solid
scape;
an
inkjet
printer
that
using
hot
wax
instead
of
using
ink
building
a
model
in
3D.
•Stereolithography
from
envision;
Uses
a
light-­‐sensi=ve
liquid
polymer.

4. “
Model
making
process
from
solidscape
”
• Transfer
the
finished
design
in
STL
file
that
created
from
CAD
to
the
machine
• Set
up
the
file
in
a
sodware
called
Modelworks
that
come
with
the
machine
• the
machine
will
apply
the
wax
layer
by
layer
to
create
3D
models
by
prin=ng
the
suppor=ng
surface
in
the
pink
wax
and
the
real
model
in
the
blue
wax.

5. • Take
the
plate
with
the
completed
models
to
the
hot
plate
so
you
can
remove
the
model
out.
• Then
place
the
pieces
into
a
cleaning
solu=on
to
clean
off
pink
base
wax
and
dry
the
pieces
to
get
ready
to
be
cast
or
making
a
mold
out
of
it.

6. “
Model
making
process
from
Envision
”
• This
machine
builds
the
model
up-­‐side-­‐down
by
laser
one
layer
at
the
=me
crea=ng
interior
and
exterior
feature
including
support
and
sprue.
• Clean
the
finished
pieces
in
a
cleaning
solu=on
and
the
piece
will
ready
to
be
direct
cast
or
make
a
mold

7. Machines
overall
• These
machines
make
the
jewelers’
lives
easier.
We
can
see
the
3D
model
from
the
CAD
program
and
then
transfer
the
file
to
the
RP
machine,
here
the
process
called
WYSIWYG
(What
You
See
Is
What
You
Get)
takes
place
wherein
the
final
product
is
same
as
the
image
created.
• The
materials
in
use
are
non-­‐toxic
thermoplas=c
for
the
solidscape
and
photopolymer
for
envisiontec
which
is
featuring
lost
wax
cas=ng:
fast
melt
out,
no
ash
or
residue
;
this
make
the
process
free
from
porosity
and
no
thremal
expansion.
• Such
a
machine
makes
no
more
=me
consuming
for
carving
wax

8. Machines
overall
• To
decrease
the
waste
of
wax
or
metal
and
also
decrease
the
development
=me
by
allowing
correc=ons
to
a
product
to
be
made
early
in
the
process
when
the
model
s=ll
be
a
STL
file.
• Increasing
product
complexity;
designers
can
be
more
crea=ve
as
the
computer
program
lead
them.
Unlike
CNC
machine
that
have
a
tool
limita=on
that
can
not
carve
a
hallow
form
and
too
complex
shape.
• To
Provide
clean
smooth
surface
of
the
prototype
and
also
precise
with
out
lower
the
speed.

9. Machines
overall
• Decreasing
delivery
=me;
3D
prin=ng
machine
and
stereolithography
(digital
wax)
works
a
lot
faster
and
making
more
pieces
in
the
same
period
of
=me
compare
to
CNC
machine.

10. Sustainability
and
environment
impact
• Non-­‐toxic
thermoplas=c
composites
will
not
harm
the
environment
where
they
are
placed.
Unlike
other
materials
that
release
chemicals
over
=me
• Thermoplas=c
is
a
polymer
that
can
remelted
and
remolded
many
=mes.
• Liquid-­‐Photopolymer
releases
26%
CFC-­‐11
equivalents
(
ozone
deple=on
factor)
• Liquid-­‐Photopolymeris
a
water-­‐base
so
no
chemical
that
harm
the
environment.

11. The
use
of
RP
machine
in
general

12. The
use
of
other
types
of
rapid
prototyping
in
many
applica=ons

13. Future
predic=on
for
the
machine
in
Jewelry
fabrica=on
• Be
more
faster
and
more
precise
• Bigger
in
size
that
could
make
the
bigger
piece
and
more
pieces
at
the
same
=me
• Become
a
main
tool
for
the
jewelry
produc=on
• No
Need
to
store
too
many
metal
models
