Direct Digital Manufacturing (DDM) is achievable utilizing the SLS
process, allowing you to quickly create durable parts that are heat and
chemical resistant. They are readily joined mechanically or with adhesives
and have an excellent surface finish. Feature definition and detail
coupled with high durability and stability make SLS an excellent choice
for producing both rapid prototype and production parts without the expense
of tooling.
Since the Selective Laser Sintering process is a Direct Digital Manufacturing
(DDM) process that does not involve tooling, the benefits of
the process increase as the complexity of the design increases. This
runs counter to traditional manufacturing processes where additional
design complexity usually involves greatly increased time and expense.
SLS production is economically viable for low complexity designs only
when the production volume is so low that the tooling and other NRE
expenses cannot be amortized over a large volume of parts. At the
other extreme, SLS production can be economically viable for even
large production volumes if the design is of sufficient complexity that it
would be difficult or impossible to fabricate the part with any other
method. SLS also becomes more viable if the product design is subject
to change going into manufacturing and avoids the additional costs and
delays of tooling changes.
