Preparing Files for Use with Objet30 3-D Printing Systems
Before
using
files
with
Objet30
3
‐
D
printing
systems,
you
must
convert
them
in
your
CAD
program
to
either
STL
files
or
SLC
files.
(For
an
explanation
of
these
file
formats,
see
After
converting
the
model
files,
it
is
recommended
that
you
check
them
for
defects
in
an
STL
‐
repair
application
(such
as
Magics,
by
Materialise)
before
opening
them
in
Objet
Studio
and
producing
the
model.
You
can
several
models
or
parts
at
the
same
time,
after
arranging
them
on
the
build
tray
in
Objet
Studio.
The
following
are
the
maximum
dimensions
for
a
single
model
printed
on
the
Objet30
printer:
•
With glossy finish—
X
axis:
294.
0
0
mm
(11.5
7
inches)
Y
axis:
192.
00
mm
(7.5
5
inches
)
Z
axis:
148.60
mm
(5.85
inches)
•
With matte finish—
X
axis:
293.
0
0
mm
(11.5
3
inches)
Y
axis:
191.
00
mm
(7.5
2
inches
)
Z
axis:
148.30
mm
(5.83
inches)
Converting
CAD Files to
STL Format
This
procedure
may
vary
slightly,
depending
on
the
CAD
software
used,
but
the
following
instructions
generally
apply.
To convert a file to STL format (in a CAD program):
1. From
the
File
menu,
select
Save As
.
2. In
the
Save As
dialog
box,
open
the
Save As Type
pull
‐
down
menu
and
select
*.STL
.
3. Click
Options
and
set
the
following
parameters:
•
Total
Quality—approximately
0.1
mm
(deviation
tolerance
/
linear
‐
dimension
tolerance)
•
Detail
Quality—approximately
4°
(angle
tolerance)
Note:
Lowering these values produces more accurate models, but
results in larger files and longer loading and processing times. For this
reason, it is generally not recommended that you use lower values.
4. In
the
file
format
option,
choose
binary
or
ASCII
.
(Both
binary
and
ASCII
formats
can
be
used
in
Objet
Studio.
However,
binary
files
are
smaller,
so
this
option
is
recommended.)
5. Click
OK
or
Save
.
Converting
Files to SLC
Format
When
converting
files
to
SLC
format,
it
is
recommended
that
you
set
a
layer
thickness
of
15
microns
(0.015
mm).
Since
SLC
files
cannot
be
orientated
in
Objet
Studio,
it
is
important
that
models
are
properly
orientated
before
being
saved
as
SLC
files.
Considerations
for
suitable
model
orientation
are
explained
in
