Abstract: 
The automotive industry is largely driven by stringent emission requirements to meet the sustainability aspects. Novel manufacturing methods are continuously probed to provide light weight transportation solutions to meet emission requirements without any compromise on crashworthiness of the vehicles. 
Selective laser heat treatment is one such novel process having great potential in serving the automotive industry. Enhanced formability and tailored material properties are possible to achieve in comparison to traditional methods. However, the process distorts the material from its nominal geometry. The nature of geometrical distortion arising from selective laser heat treatment, and from combination of selective laser heat treatment and forming process is a domain that requires further exploration. 

The presentation discusses geometrical distortion arising from selective laser heat treatment of boron steels. Results from industrial case studies highlight the need for geometrical assurance to minimize effect of variation in the final product that may arise from the process.
