• Wood: Natural wood coasters, such as bamboo, maple, or walnut, provide a warm, organic look. They engrave well and can showcase intricate designs while offering functionality.
• Leather: Leather coasters have a unique texture and can be laser engraved to create stunning, personalized designs. They are durable and provide a touch of elegance.
• Stone: Materials like slate, marble, or granite not only add luxury but also make excellent surfaces for laser engraving. These coasters are heat resistant, making them ideal for hot beverages.
• Acrylic: Acrylic coasters are lightweight and come in various colors. They engrave clearly and can be made to look like glass, providing a modern touch.
• Glass: Glass coasters can be beautifully engraved, offering a sleek and polished finish. They are perfect for showcasing detailed graphics and designs.

When selecting materials, consider the intended use, desired aesthetics, and the engraving capabilities of your laser machine to achieve the best results.
