Laser cutting machines can cut a diverse range of materials, providing versatility for various applications.
Materials Suitable for Laser Cutting
The following materials are commonly cut with laser cutting machines:
- Acrylic: Also known as PMMA, acrylic is a transparent plastic known for its strength and clarity.
- It's often used for signs, displays, and protective covers.
- Plywood: Made from bonded wood veneers, plywood is a versatile material suitable for laser cutting.
- It’s used in model making, furniture, and packaging.
- MDF (Medium-Density Fiberboard): MDF is an engineered wood product that cuts cleanly with lasers.
- It's frequently used in furniture and decorative items.
- Cardboard: Cardboard is a cost-effective material perfect for laser cutting prototypes and packaging.
- It's easily cut and ideal for various design projects.
- POM (Polyoxymethylene): A strong engineering thermoplastic, POM is used for parts that require high precision.
- Its stability and mechanical properties are well-suited for laser cutting.
- Foam: Different types of foam can be laser cut for packaging, inserts, and crafts.
- Its flexibility makes it a great choice for protective padding.
- Metal: Certain metals can be cut using laser cutters, especially when equipped with powerful lasers.
- Commonly cut metals include stainless steel and aluminum.
- Leather: Leather is often laser cut to make products like wallets, belts, and decorative items.
- The laser allows for detailed and intricate patterns.
