The ideal material for bringing concepts to life. Rigid yet lightweight, these fine-grain urethane foams cut cleanly in all directions, with no knots to work around like with wood. They’re a popular choice for production tooling, architectural models, 3D topographical maps, and other designs where the details matter. Machine them using standard high-speed steel cutting tools or carve them by hand using common woodworking gear. The foam’s closed-cell structure absorbs no moisture and won’t deform when wet, so you can paint them, too.
