Plywood is a manufactured composite sheet material consisting of thin layers of wood veneer that are bonded together with an adhesive. Plywood is also known as laminated or engineered wood. Plywood can be processed with a 9.3 or 10.6 micron CO2 laser without a noticeable difference in process quality. Plywood does not readily absorb the energy of the 1.06 micron fiber laser and is not recommended for use with this material. Laser cutting of plywood can be performed with a CO2 laser, producing a squared edge cut with some darkening at the cut surface. Laser engraving of plywood can be used to create features with depth and high contrast. Depending upon the process and specific material used, laser engraving and marking plywood can vary from a slight color contrast with the surrounding area to a high contrast dark effect on the material.
