Directed Energy Deposition (DED) has long been a technology suited for the formation of functionally graded material (FGM) systems due to its ability to use multiple materials within the same build, open source parameters, and low material consumption. However, combining dissimilar materials can be a challenge. To reduce residual stresses between the materials, a gradient transition can be used. In the past, the DED process relied on on-the-fly blending or introducing additional feeder to deposit the transitions. But for intricate transitions, this is not a viable long term solution. With that in mind, FormAlloy developed their ADF Alloy Development Feeder. Within the ADF, up to 16 different compositions can be deposited quickly. A revolver style hopper systems enables rapid transition from 1 hopper to another, and feeder operation features help prevent cross-contamination between materials. Discover how the ADF and DED process looks to provide the means for detailed FGM systems. |
