Proofgrade Plywood is an ideal choice for scale model designs, wall hangings, and desktop accessories. Proofgrade plywoods are custom fabricated with an engineered wood core surrounded by a micro-thin layer of natural hardwood, resulting in a strong, beautiful, and versatile material that you'll use every day. Glowforge matches hardwoods, plywoods, and veneers, so you can combine all three for a consistent and professional look. Each board is coated with a furniture-grade semi-gloss finish, and protected with a removable paper sheet, and encoded with a barcode for perfect settings. As a result, each print looks incredible straight out of the laser. Proofgrade plywood cores are engineered to be predictable from board to board, giving you the same consistent results from every print. The beautiful hardwood outer layer is a natural product, so each board will have a distinctive pattern and grain all its own.
