10 Laser Cutting Materials You Need to Know

Why is Laser Cutting Used?

Many businesses and people seek out laser cutting services as its precision, speed and versatility are unmatched compared to traditional cutting methods. A focused beam of light is used to melt, burn and vaporise different materials with incredible accuracy. The technology allows for clean, detailed cuts on a wide range of materials, including metal, plastic, wood and composites.

Laser cutting is highly favoured for its high precision and repeatability, making it ideal for complex shapes, fine details and tight tolerances in stencils and profiles. Laser cutting is also a non-contact process, meaning there’s minimal risk of material distortion or contamination. This means that thinner materials for laser cutting are viable.

Sustainable laser cutting offers excellent efficiency, reducing waste and lowering production time thanks to fast processing speeds and minimal post-processing. It can also be automated and integrated with CAD/CAM design systems with ease, streamlining the entire process from design to production.

We’ve defined the technology in more detail in our informational guide: What is Laser Cutting?

Importance of Material Selection

With the range of laser cutting materials available, each one will react and cut differently. Choosing the right material is crucial to achieving the best results, especially for detailed work like stencil creation. You need to consider material thickness, burn risk, melting point and edge quality, as certain thicknesses are prone to burning and can lead to rough edges, warping or loss of detail.

It’s not just about the chosen laser cutting material either – the type of laser being used also plays a role.

•         CO2 lasers – ideal for cutting non-metallic materials like wood, acrylic and paper, offering smooth finishes and clean edges.
•         Fibre lasers – best for cutting metals with high speed and precision but may not perform well on softer materials.

Many say the best material for laser cutting stencils should be thin and heat resistant – think acrylics and Mylar, thanks to the minimal risk of melting and the benefit of maintaining sharp edge definition. For stencils, you should avoid materials that emit toxic fumes, such as PVC, or those with inconsistent density.

Choosing the right materials along with the right laser cutter is key to achieving the finished product you’re after. If you’re ever in any doubt about which material you need cutting, our experts are available to talk.

Laser Cutting Materials: FAQS

Which materials shouldn’t be cut with a laser cutter?

There are certain materials unsuitable and unsafe for laser cutting. PVC, polycarbonate and materials containing chlorine or formaldehyde release toxic fumes that can damage machinery and harm operators. Highly reflective metals, including aluminium, copper and brass, can also be challenging to cut without specialised fibre laser systems.

How do I choose which material to use?

A good starting point in choosing the right material for laser cutting is to identify your application. Does it require flexibility, strength, clarity or heat resistance? Consider the thickness, finish quality and how the material reacts to heat. If you’re cutting stencils, opt for Mylar or acrylic. For industrial parts, stainless steel and aluminium are ideal. Consulting with the laser cutting experts at Central Profiles can help you make the right choice.

What is the thickest material a laser cutter can cut?

The maximum thickness depends on the laser type and power output. High-powered fibre lasers, like the ones found at Central Profiles, can cut up to 25-30mm of mild steel, while CO2 lasers are generally suited for thinner materials. Always check machine capabilities and material compatibility to avoid poor cut quality. We operate both fibre and CO2 lasers to ensure compatibility with the widest range of materials possible.
