Light Plywood takes your projects from start to finish quickly. Compared to Medium Plywood, Light Plywood is thinner, weighs less and cuts twice as fast. The core is natural hardwood, rather than engineered material, so it's stronger in one direction than the other. That makes it ideal for structural designs, but less suitable for delicate cuts like living hinges. Proofgrade plywoods are custom fabricated with a hardwood core (for Light and Thick) or an engineered wood core (for Medium) surrounded by a micro-thin layer of natural hardwood, resulting in a strong, beautiful, and versatile material that you'll use every day. 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.
