How can you prevent laser reflections from damaging the backside of acrylic during cutting?

During acrylic cutting, the laser can penetrate the material and strike the honeycomb bed, causing reflections from the metal mesh that can damage the backside of the acrylic, leaving visible marks. To reduce these reflections and minimize damage, consider the following approaches:

1. Damp Paper Towels: For smaller areas, place damp paper towels on the honeycomb bed to absorb and weaken the reflected laser energy, protecting the acrylic.
2. Nailboards for Larger Areas: Use nailboards to elevate the acrylic, reducing the amount of reflected laser energy that reaches the backside of the material and preventing damage.
3. Knife Bar Cutting: Cutting on a knife bar is preferable as it is less dense than a honeycomb bed, which reduces the amount of laser reflection. This method works best when cutting from the inside out, though it may not be ideal for tiny parts.

Optimize Cutting Parameters: Increase the cutting speed and reduce the laser power to lower the energy reflected during the process, helping prevent acrylic damage.

Always consider the specific machine settings and acrylic thickness when adjusting for safety and optimal cutting results.
