Wood & MDF Signage: CNC Laser Engraved & Cut

For instance, MDF signage offers a smooth, consistent surface that results in sharp, dark engravings. A laser can create a smoky effect on MDF, which can be either left as is for a rustic look or sanded down for a cleaner finish. Masking before engraving also helps achieve a crisp result. Comparatively, bamboo produces a much cleaner engraving without the smoky residue, offering a polished appearance right out of the laser. The choice between a smoky or clean finish ultimately depends on the aesthetic preference of the client.

However, real wood has its own unique advantages. Pine, for example, is lightweight, versatile, and easy to work with using laser cutting, CNC routing, and bandsawing. While pine is great for signage, it does have natural variations in grain, color, and density, sometimes resulting in knots or areas of dry rot. Bamboo, in contrast, is much denser and heavier, similar to MDF in its uniformity but significantly more durable.

When choosing wood for custom signage, durability and intended use are key factors. Hardwoods like oak, ash, and maple offer superior strength and longevity, making them ideal for outdoor signage that needs to withstand varying weather conditions. A live edge slab of ash, for example, adds a rustic, natural aesthetic, perfect for cottage signs or house numbers. However, live edge wood often contains natural imperfections such as wormholes or embedded nails, which can be revealed during the CNC routing process.

Another important consideration when selecting wood is whether or not knots are desirable in the final design. Some clients prefer the natural, organic look of knots, while others require a clean, flawless surface. If a knot-free sign is needed, specific wood species and high-quality cuts must be selected to achieve the desired finish.
