Exploring the Advantages of Laser Engraving Acrylic Materials

In contrast, extruded acrylic sheets offer advantages in terms of thickness tolerances. They are suitable for single variety, high-volume production. With adjustable sheet lengths, it is possible to produce longer and wider acrylic sheets. The ease of bending and thermal forming makes them ideal for processing larger-sized sheets, facilitating rapid vacuum forming. The cost-effective nature of large-scale production and the inherent advantages in size and dimensions make extruded acrylic sheets a favorable choice for many projects.

However, it’s important to note that extruded acrylic sheets have slightly lower molecular weight, resulting in relatively weaker mechanical properties. Additionally, the automated production process limits color adjustments, imposing certain limitations on product color variations.

Acrylic Sheets: Optimizing Laser Engraving Parameters

When laser engraving acrylic, optimal results are achieved with low power and high-speed settings. If your acrylic material has coatings or additives, it’s advisable to increase the power by 10% while maintaining the speed used for uncoated acrylic. This provides the laser with additional energy for cutting through painted surfaces.

Different acrylic materials require specific laser frequencies. For cast acrylic, high-frequency engraving in the range of 10,000-20,000Hz is recommended. On the other hand, extruded acrylic may benefit from lower frequencies of 2,000-5,000Hz. Lower frequencies result in lower pulses, allowing for increased pulse energy or reduced constant energy in the acrylic. This phenomenon leads to less boiling, reduced flames, and slower cutting speeds.
