Laser-Based Additive ManufacturingWillow Laser Cleaning Settings
When laser cleaning Willow, start with low power and slow scan speeds to gently lift surface grime without scorching its delicate fibers. This wood's high porosity soaks up contaminants deeply, which helps the laser absorb well and clear buildup effectively, but it also traps heat locally due to poor conductivity, so you must overlap passes carefully midway through to prevent uneven charring or cracking. Avoid rushing the process—multiple light treatments bring back that natural grain safely.

Parameter Relationships
Shows how changing one parameter physically affects others. Click any node to see its downstream impacts and role.
Power Range
Amplifies damage risk in Pulse Width and Energy Density. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
Energy Density
Higher power delivers more energy per pulse, removing more material.
Pulse Width
More power means higher peak intensity. Too much can damage the material.
Pass Count
Using more passes means you can use lower power and still get the job done.
