Over the past few years, the AM industry has shown that with the right controls in place consistent mechanical properties can be achieved. The clear majority of this testing has been performed according to ASTM standards that drives to a fully machined surface. Little research has been performed on the effect surface finish has on mechanical properties. The presentation will focus on how surface finish can affect mechanical properties (fatigue and tensile) and how these variables can be overcome in the design stage to lower overall part cost.
- Understand to how better design AM components with as fabricated surfaces as compared to fully machined
- Determine how various mechanical properties are affected by various surface conditions
- Analyze the cost benefits of utilizing as fabricated AM components vs. fully machined
