The Challenges of Laser Cutting Acrylic
Laser cutting technology is widely used in the processing of various materials, including acrylic. Acrylic is a common plastic material with excellent transparency, toughness and weather resistance, so it is widely used to make furniture, decorations, display stands, etc. However, there are some challenges when laser cutting acrylic with the Atomstack. This article will explore the challenges of laser cutting acrylic and suggest solutions.

First of all, acrylic material is very sensitive to optical radiation. High temperatures are generated during laser cutting, which can cause annealing and discoloration of acrylic materials. Not only will this result in uneven cut edges, but it will also reduce the quality and aesthetics of the acrylic. To resolve this issue, the following actions can be taken:

Control Atomstack S20 Pro laser power and speed: Properly reduce laser power and speed to reduce local heat accumulation, thereby reducing the temperature of acrylic materials.

Improve cutting quality: By optimizing the parameters and focal length of the laser beam, reducing the cutting gap and reducing local heat accumulation, thereby improving the cutting quality.

Secondly, acrylic materials are prone to cutting tails. Due to the characteristics of acrylic, the laser is prone to air film and pores when cutting the material. These air films and pores can cause uneven or uneven tailing on the cut edge. To solve this problem, we can consider the following methods:

Pretreatment of the surface of the acrylic material: Before cutting, the surface of the acrylic should be specially treated, such as spraying, cleaning or coating with cutting aids. These methods can reduce the air film and porosity produced during cutting.

Adjust laser parameters: By optimizing laser power, speed and focus, control heat transfer and gas removal during cutting, and reduce the generation of cutting tailings.

Finally, acrylic has a relatively low melting temperature. It is easy to quickly reach and exceed the melting temperature of acrylic during laser processing, resulting in material melting and damage. To avoid this from happening, consider the following:

Use gas purging technology: During the cutting process, the cutting area is cooled by spraying nitrogen or other inert gases, thereby reducing the temperature of the acrylic material and the risk of melting.
Pay attention to the material thickness and cutting speed: according to the thickness of the acrylic material, choose the cutting speed reasonably to keep the balance between the laser power and the thermal conductivity of the material. Appropriately reducing the cutting speed can reduce the temperature of the material.

To sum up, the challenges faced by laser cutting acrylic mainly include problems such as heat affected zone, cutting tailings and melting risk. By reasonably adjusting Atomstack S10 Pro laser parameters, processing surface pretreatment and using gas purging technology, these problems can be effectively solved and the quality and efficiency of acrylic cutting can be improved. At the same time, continuous exploration of innovative processing methods and new technologies to improve material properties are also important ways to solve these challenges.
