This FDM fan blade prototype, provided to a customer for evaluation, was built with ULTEM™ 9085 resin because its high temperature performance enabled functional testing.
This FDM part (top and side view) allows testing of four variations of a groove that mates with a rubber seal.
The FDM prototype of the four variations took only 2.5 hours and $10 of material. The Fortus system has reduced the cost of building the complete three-component housing by $2,000 and the leadtime by 3 weeks compared with using a service bureau. “The Stratasys solution of being able to make production-grade components one-off enables us to deliver functional prototypes to customers at a much faster speed,” Hansen concluded. “FDM prototypes are more useful than the SLA and SLS prototypes because they can be used for physical testing and even given to customers as components on valuation units. This means that we are nearly certain to get the design right the first time so we can keep customers happy and start generating revenues sooner.”
