What happens when the laser beam shape changes during an additive manufacturing process?

In this simulation, the laser beam shape is dynamically changed every 0.3 milliseconds — transitioning from Gaussian → Elliptical → Ring.

The result is a fascinating change in the melt pool dynamics, solidified geometry, thermal behavior, and laser–material interaction.

Using the laser beam shaping capabilities of AM PravaH, we can simulate a wide range of conventional and advanced beam profiles, including:

• Gaussian

• Elliptical Gaussian

• Ring

• Bessel

• Double Ellipsoid

• Top-Hat

• Multi-Gaussian

• Star

• Fish

• Half-Moon

• And other customized beam shapes

Dynamic beam shaping can provide valuable insights into how changing the spatial energy distribution of a laser influences the additive manufacturing process.

This type of simulation can help researchers and engineers explore process optimization, melt pool control, thermal behavior, and novel laser-material interaction strategies before conducting extensive experimental trials.

Watch the simulation to see how quickly the melt pool responds when the laser beam shape changes.
