4 cards from this section. Quick, good the night before a test.
What is one key parameter that affects melt pool dynamics in PBF?
Think about the energy source used in the process.
How does layer thickness influence the final product?
Consider how thicker layers might change the way parts fit together.
What is the impact of increasing the laser power in PBF?
Consider what happens to the energy distribution with higher power.
Is it true that higher scan speed always leads to improved surface finish?
Think about how all aspects of PBF interact.
Evaluate how different materials (metals vs. polymers) will react to identical PBF parameters. Discuss the expected differences in grain structure and mechanical properties.
Consider thermal characteristics of both categories.
Design a controlled study involving PBF parameters to optimize for minimal residual stresses in a titanium alloy application. Outline the methodology and expected outcomes.
Think about the control of cooling and how it can affect stress.
