Additive Manufacturing (Page 18)

In the manufacturing world, robotic welding systems are making their way into directed energy deposition (DED) AM production. EWI recently converted, demonstrated, and validated an IPG Genesis robotic welding cell for DED AM use. The system is dimensionally accurate and ready to build large-scale AM parts. This project is described in IPG Genesis Robotic DED...

Wire DED as a large-scale additive manufacturing method is highly promising, but until now there has not been an effective robotic system for wire delivery. That has changed with the development of EWI’s coaxial laser wire DED solution which has demonstrated one of the highest build rates in AM. You can learn about this project...

Inconel 718 components produced using additive manufacturing (AM) generally require heat treatment to form strengthening precipitates and optimize the phase fractions of all precipitates. Work done at EWI has been focused on developing a heat treatment procedure specifically for AM-generated IN718 parts. The results of this research are discussed in Optimization of the Post Heat...
