Proofgrade Draftboard is an engineered wood material designed to help you inexpensively draft structural and decorative wood projects. Its thickness matches Proofgrade hardwoods and plywoods, so you can run a trial print to work out the kinks and ensure hinges or other joinery fits flawlessly before printing a final version using finished materials. Proofgrade Draftboard cuts and engraves cleanly on its smooth, unfinished brown surface. While it’s humble in appearance, it takes paint well and can be used for some projects as-is. Like all Proofgrade materials, it is masked on both sides with a protective removable paper masking, and barcoded to ensure every print comes out perfectly. Details: Unfinished 12" x 20" overall size Medium: 1/8" thickness Engineered wood For use with Glowforge 3D laser printer and for any CO2 laser cutter / laser engraver (sold separately)
