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.
