Proofgrade Eco Thin acrylic takes your projects from start to finish quickly. Compared to Medium Acrylic, it's thinner, weighs less, and cuts twice as fast. Proofgrade Acrylic is waterproof, stronger than glass, works with superglue, and can be heated and molded into different shapes. We only source cast acrylic, which is more suitable for laser projects, so you get smooth, polished cuts with every print. With digitally encoded smart technology, your Glowforge instantly recognizes the material and inputs the ideal settings for perfect prints every time. A protective masking covers your materials through the printing process for sharp, clean results. When the print is done, peel it off to reveal your finished masterpiece.
