Polyisocyanurate foam has been a favorite material of pattern builders for years. Available in multiple sizes so you can cut, carve, sand, and sculpt any shape imaginable without gluing numerous sheets together or pouring your own block. Although this foam can be easily CNC machined, it should not be hot wired. Professional results can be achieved when working by hand. With the variety of tools available on our site, you can saw, carve, plane and smooth out your shape. You will then lay layers of fiberglass and resin to protect and strengthen your shape. Finally, you will spray Duratec® Surfacing Primer and buff to a perfect shine. A perfect plug allows for a perfect mold which makes the high gloss, perfect part you want.

Smaller block allow for making smaller projects or to practice on smaller pieces before buying a full block. Available in one foot and two foot cubes.
