What to Consider When Choosing Materials for Laser Cutting
Laser cutting is a versatile and precise cutting technique that can be used on a variety of materials. However, before sending a request for laser cutting, it's essential to know what kind of material you want to use. Each material has unique properties that may affect the laser cutting process, such as its thickness, density, and flammability. In this blog post, we'll review some things to consider when choosing materials for laser cutting.
Acrylic
Introduction to Acrylic for Laser Cutting
Acrylic is a popular material for laser cutting because it is a thermoplastic with many uses, including in manufacturing signs, displays, point-of-sale items, and protective barriers. Its popularity stems from the fact that it is versatile and comes in a variety of colors and thicknesses. It is also known for its high clarity and transparency, making it ideal for applications that require optical clarity.
Importance of Acrylic Quality for Laser Cutting
One of the key considerations when laser cutting acrylic is the quality of the material. Acrylic can be prone to warping or melting during the laser cutting process if it contains impurities or if the material has been improperly stored. Therefore, ensuring that the acrylic you use is high quality and free from impurities is crucial.
Considering Acrylic Thickness for Laser Cutting
The thickness of the acrylic is a critical factor to consider when laser cutting. Thin acrylic sheets can be cut swiftly and precisely, yielding excellent results. However, thicker acrylic requires multiple passes to complete the cut, which poses a higher risk of charring or melting the material. Such undesirable outcomes can significantly impact the final appearance and functionality of the product. For optimal outcomes, we recommend a maximum thickness of ¼". It is important to note that anything thicker than that would require multiple passes, making it challenging to cut properly. Hence, exceeding this thickness for optimal cutting results is not recommended.
Ensuring Acrylic Durability for Laser Cutting
Acrylic can be sensitive to temperature changes and become brittle over time. Therefore, it's important to choose the right acrylic thickness for your project and store it properly to ensure that it retains its strength and shape.
Benefits of Laser Cutting with Acrylic
Overall, acrylic is an excellent material for laser cutting because of its versatility, clarity, and durability. By choosing the right quality and thickness of acrylic and taking appropriate safety measures, you can produce precise and beautiful cuts for various applications.

Wood
Introduction to Wood for Laser Cutting
Wood is a popular laser-cut material because of its natural beauty and versatility. However, it's important to consider the type of wood and its density when choosing it for laser cutting.
Considering Wood Type and Density for Laser Cutting
Hardwoods like maple and cherry are dense and can be more challenging to cut than softer woods like pine or balsa.
Wood Thickness and Laser Cutting Considerations
The thickness of the wood plays a significant role in the laser-cutting process. When the wood is excessively thick, it may necessitate multiple passes to achieve a complete cut, increasing the risk of charring or burning the material. For optimal results, we generally recommend a maximum thickness of ¼". This guideline ensures more precise and controlled cuts while minimizing the potential for undesired charring or burning effects.
Achieving the Desired Finish on Laser-Cut Wood
When laser-cutting wood, achieving the desired finish requires careful consideration. The process can result in either a smooth, polished edge or a charred appearance, depending on the calibration of the settings. While it may seem possible to cut wood without charring the edge by adjusting the settings, this is actually not the case, especially with organic materials like wood. This misconception often arises when clients expect a char-free edge, which is not achievable.
However, there are techniques that can help minimize the appearance of charring. If you prefer a natural, unfinished look, you can try using a lower power setting or applying masking tape to the wood before cutting. While tape can reduce burn marks on the surface, it may not entirely prevent charring along the edges. It's important to note that even with multiple passes at lower power settings, some charring may still occur since the laser is repeatedly passing over the same area.
In my experience, regardless of the precautions taken, some degree of charring is inevitable along the edges. However, by adjusting the settings and employing techniques like tape masking, you can achieve a more controlled and desirable finish for your laser-cut wood projects.
Warping and Distortion: Considerations for Laser Cutting Wood and Acrylic
Another crucial factor to consider when laser cutting wood is the possibility of warping or distortion of the material. Wood is known to be sensitive to fluctuations in temperature and humidity, and the introduction of heat through laser cutting can exacerbate this issue, leading to warping or bending of the wood. To mitigate this risk, it is essential to select stable and well-seasoned wood that has been stored correctly to minimize its susceptibility to environmental changes. It's worth noting that similar considerations apply to acrylic when it undergoes laser cutting, as various factors can contribute to the material starting to bend or warp due to the intense heating it experiences
Creating Stunning Laser-Cut Wood Products
Wood is a beautiful and versatile material for laser cutting, but it requires careful consideration of its type, density, finish, and safety implications. By selecting the correct type of wood, calibrating the laser cutter properly, and taking appropriate safety measures, you can create precise and stunning cuts for various applications.

Fabric
Introduction to Fabric for Laser Cutting
Fabric is a versatile and popular material for laser cutting. It can be used in various applications, including manufacturing clothing, upholstery, and decorative items. However, it's important to consider the type of fabric and its thickness when choosing it for laser cutting. Thicker fabrics, such as denim or canvas, can be more challenging to cut than thinner fabrics, like silk or chiffon.
Considering Fabric Type and Thickness for Laser Cutting
When laser-cutting fabric, it is crucial to consider the desired finish for the final product. Laser cutting offers the advantage of producing a clean and sealed edge on fabrics, making it an ideal technique for creating patches or appliques. However, if the laser settings are not properly calibrated, it can lead to a burned or melted appearance, similar to wood cutting. In such cases, adjusting the settings may not rectify the charred edge, as it depends more on the fabric's composition. Fabrics with higher synthetic content, containing more plastic, are prone to melting easily and can result in rough, sealed edges.
To prevent these undesired effects, it is essential to conduct a test by laser cutting a small piece of fabric with the intended settings before cutting the entire design. This enables you to assess the outcome and make any necessary adjustments to achieve the desired finish while minimizing the risk of burning or melting the fabric. By taking this precautionary step, you can ensure that your laser-cut fabric projects result in professional-looking and well-finished products.
Achieving the Desired Finish on Laser-Cut Fabric
Another consideration when laser cutting fabric is the potential for warping or distortion of the material. Some fabrics can be sensitive to heat and moisture, which can cause them to shrink or stretch. To minimize this risk, choosing a stable and well-maintained fabric that has been properly stored is important.
Creating Beautiful and Precise Laser-Cut Fabric Products
Overall, the fabric is a versatile and attractive material for laser cutting, but it requires careful consideration of its type, thickness, finish, and safety implications. By selecting the right kind of fabric, calibrating the laser cutter properly, and taking appropriate safety measures, you can create precise and stunning cuts for a variety of applications.
Don't let fabric thickness or warping hold you back.
Fabric Types for Laser Cutting
