Laser-Based Additive ManufacturingFiber Reinforced Polyurethane FRPU Laser Cleaning Settings
When laser cleaning Fiber Reinforced Polyurethane, we typically begin with a gentle power setup to match its flexible yet tough composite structure. This material absorbs laser energy well, so it clears contaminants quickly without deep penetration. But watch out mid-process—its low heat spread can cause localized overheating, leading to fiber-matrix separation. We've found multiple light passes at steady speeds fix that, restoring the surface evenly for aerospace or automotive parts.

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.
