Materials

EPS (expanded polystyrene) is a lightweight, insulating and easily machined material often used for insulation and packaging. Advantage: Insulation, lightweight, easy to machine, wide range of different densities from very soft to hard. Disadvantage: Spherical texture.

XPS (extruded polystyrene) is a strong and durable material often used for insulation, cladding and roofing. Advantage: Strong, durable, good insulation, no ball texture but smoother appearance than EPS. Disadvantage: Only one hardness available and limited in dimensions.

PU (polyurethane) is a plastic material often used for insulation, cladding and foam. Advantage: Good insulation, lightweight, PU80 is firmer and finer to finish than EPS or XPS, well sandable and can hold a lot of detail. PU40 is easier to process than PU80. Disadvantage: Not recyclable.

Biofoam is an eco-friendly foam based on biological raw materials, often used as an alternative to traditional foams. Advantage: Biodegradable, environmentally friendly. Disadvantage: Can be more expensive than traditional foams.

Wood fiberboard is a material made from compressed wood fibers, often used for insulation, wall covering and as a substrate for floors. Advantage: Environmentally friendly, natural insulation material. Disadvantage: Not moisture-resistant.

MDF (Medium-Density Fibreboard) and is a material made by pressing wood fibers together with a binder under high pressure and temperature. The result is a smooth and dense board material used in the furniture and construction industries. Advantage: Smooth surface, uniform structure. Disadvantage: Sensitive to moisture and not suitable for outdoor projects.
