                    Laser cutters are increasingly relevant within many user contextsand have  
become an essential tool for model building and prototyping. While providing  
precision and flexibility, these tools are typically suited for expert staff  
in industrial settings. VAL (Visually Augmented Laser cutting) proposes a  
novel system utilizing spatial augmented reality techniques to provide visual  
augmentation directly on the work surface. VAL involves projection of the  
user’s model prior to and during laser cutting providing key benefits  
including minimizing idle time, reduction of errors, and support for new  
creative practices. We interview and observe laser cutter users to identify  
issues and concerns in the shared work context of a design school and  
describe the design process for our prototype, which aims to address these  
problems and unmet needs. Initial evaluation suggests VAL reduces complexity  
and raises user confidence. Our findings extend research on adapting new use  
contexts and creative practices with industrial fabrication tools.
