As a material, acrylic requires a higher frequency when laser cutting compared to other common materials such as wood. The higher frequency distributes the energy evenly into the material. This causes an even melting of the laser cut acrylic edges creating a glass-clear, flame-polished edge.
- For GS materials, we recommend a frequency of 5,000-20,000 Hz
- For cutting XT materials, a frequency of a max. of 5,000 Hz.
If the frequency is too low, fine ridges, also known as chatter marks, become visible on the laser cut edges. To counteract these, increase or lower the frequency of the laser cutting speed. However, if the cutting speed is too slow, this can lead to a cutting kerf below which increases the risk of fire.
It is important to figure out the perfect parameters when working with acrylic to work safely and efficiently.
