MDF - Exterior Grade
This material is a game-changer in the world laser engraving! The quality of the plywood is exceptional, with a perfectly smooth, perfectly flat surface (no surprise here) that makes it a joy to work with. The finish feels a little plastic, but I understand it’s an acrylic coating over the maple fibre, which I love. Even laser-fog burn marks wipe off with a damp cloth — no masking needed. The maple grain is pronounced and it cuts cleanly and sands beautifully. 100% will purchase again.
These work well with my Festool 125 RO in the fine mode as they leave no sanding marks compared to non festool discs.
Very satisfied....the oak grain was beautiful...milling was A1 and glued together with no problems....will buy from here again
