At Kreysler we use a variety of materials, although for most projects we are machining one of three types of foam:
- Urethane
- Expanded Polystyrene (EPS)
- Dow Styrofoam construction billets
Each is manufactured in a range of densities and each has different strengths and weaknesses depending on the nature of the project and the budget.
Kreysler Digital Fabrication is part of Kreysler & Associates, a fiberglass and composites fabrication shop. We have a lot of experience with the machining of patterns and molds specifically for composites applications. See the Kreysler main site for more information about composites.

Urethane foam is an ideal material for machining high quality shapes for art and architecture. It is often yellowish-beige and sometimes is dyed blue, green, or any other color depending on the manufacturer. It is very homogeneous and once machined it is easy to modify by hand using typical sculpting tools, rasps, sandpaper, knives, and saws. Chemically it is very stable and therefore can accept a variety of coatings such as clays, paints, or resins, without dissolving. We use three and four pound per cubic foot (3# and 4#) density urethane foam for many applications. For larger sculptures 2# urethane may be applicable and for smaller sculptures or very high precision applications 6#, 10#, 15# or even higher densities might make sense. [Examples: bat, river prototype]
