Laser-Based Additive ManufacturingPlywood Laser Cleaning Settings
When laser cleaning plywood, unlike solid hardwoods, its layered structure and high porosity make it more forgiving on heat buildup, so it tends to clean evenly without deep charring if you keep passes light and quick. I've seen this layered makeup absorb contaminants well, restoring surfaces in furniture or heritage pieces, but watch midway—too much dwell can delaminate edges, so adjust speed up to avoid that pitfall and preserve the glue bonds.

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.
