Laser-Based Additive ManufacturingAlabaster Laser Cleaning Settings
When laser cleaning alabaster, you must prioritize its softness compared to harder stones like marble, as it scratches easily under aggressive energy. This low durability means the material absorbs heat unevenly, risking cracks if you push too hard right away. Start with gentle passes at lower intensities to lift surface dirt without stressing the pores, which trap residues but also make it fragile. Watch for discoloration mid-process—dial back if you spot yellowing, and follow up with a cooling interval between sweeps. This approach preserves the fine texture alabaster brings to sculptures and heritage pieces, restoring clarity without harm.

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. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
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.
