Our walnut veneer has a walnut veneer face and a medium-density fiberboard core.
The exterior A face is furniture-grade hardwood, but because the veneers are laminated to an MDF core, the material is very smooth, solid, and dimensionally stable. The back, or B side, can vary, but is typically an oak, maple or birch face.
MDF (Medium-Density Fiberboard) is made from pre-consumer recycled wood, usually sawdust from a sawmill or wood chips from lumber operations. The wood particles are mixed into a dough with a polymer binder (e.g., glue or resin) and consolidated under heat and pressure to form a panel.
Laser Cutting
Laser cutting walnut with MDF Core works beautifully, with most lab cutters cutting up to 1/4in and many cutting up to 1/2in or more. The laser does leave a dark charred edge. Most people leave it as is, but if you prefer, you can easily sand the edges
