WHAT
IS SLS?
| Process:
SLS
(Selective Laser Sintering) is a rapid prototyping/rapid
manufacturing process by which fine, heated powders are
melted by laser to produce fully functional parts. Your
parts will be built in the Vanguard Sinter Station 2500plus
which has a build envelope of 12" x 14" x 17".
Part tolerances are +/- .003" per inch for prototype
runs and can be adjusted for greater accuracy on subsequent
manufacturing runs. Most builds will be completed within
a 1-3 day time period getting |

your product
to market faster than your competitors'.
 |
Benefits:
Since
SLS parts are built layer by layer and uniquely sintered,
not machined or molded, you have the freedom to make design
adjustments for future runs. Parts can be designed without
regard for draft angles or machine restrictions. This
makes SLS a perfect candidate for parts with complex geometries
and detail. Parts can also be |
machined
or worked after the fact to add threads, holes, or other features.
Your parts will come out manufacturer quality in a fraction
of the time and cost. That means less out of pocket costs to
develop your parts.
| Uses:
SLS
is highly useful in Automotive, Aeronautical, Medical,
Outdoor rugged, and enclosure applications. SLS is especially
practical for In vivo, Form, Fit, Snap Fit, and Chemical
testing (SLS parts are 100% chemical resistant, and can
be sterilized with an autoclave). In addition to being
excellent for functional prototypes, SLS is one of the
only Rapid Prototyping processes that can double as a
Rapid Manufacturing Process. Your parts will go |
 |
from Solid
Works to production with the click of a mouse.
 |
SLS
vs. SLA: Since
SLA parts will absorb moisture, their material properties
are known to degrade over time causing parts to become
brittle. For that reason SLS parts are traditionally better
parts for mild to highly aggressive functional testing.
SLS parts will uphold their original material properties
from the time they leave the build chamber providing you
with a durable, reliable, rugged part. |
| SLS
vs. FDM: Both
SLS and FDM produce parts with similar qualities in accuracy,
detail and surface finish. Unlike SLS however FDM is unable
to mimic nylon material properties. In addition, though
it is true that FDM is available in ABS plastic, it does
not exhibit the same durability as injection molded ABS
and |
 |
therefore
is not reliable to mimic injection molded parts. SLS parts will
more accurately
mimic the strength of injection molded ABS. Finally, speed and
cost are also a consideration. SLS is a much faster process
and more cost effective where multiple parts are required.
