Block modelling

Many models are carved out of a solid material or built up in blocks. They are particularly useful for exploring styling features, ergonomics etc.

Description of Materials:

Styrofoam

Styrofoam is one of the softest materials to shape by carving and sanding down. However, it is difficult to glue pieces together effectively. It can be painted with emulsion paints to give a reasonable impression of the final product. For a better finish, coat with a thin layer of decorator's filler, rub smooth and build up the paint layers.

Typical modelling applications include plastic bottles, hand held electrical products and vehicle bodies.

Balsa wood

Balsa wood is often used for block modelling as it will allow most traditional construction techniques, such as sawing and drilling, to be used. The fibrous nature of the material means that fine details are usually better glued on. Once smoothed and sealed, a range of paint finishes can be applied.

Typical modelling applications include some furniture and electronic products.

Medium Density Fibreboard (MDF)

MDF is much harder to work but will often give a more superior model, as it provides a much better surface for paint finishes, including spray paints, and allows fine details to be machined or applied.

Typical modelling applications include electronic products, buildings and furniture.

Acrylic blocks

Acrylic blocks (which can be acrylic sheets glued together) can be machined and are particularly effective where forms are mainly rectangular and precision is required. They will accept screw threads, so extremely durable models can be constructed. High quality spray paint finishes are possible.

Typical modelling applications include electrical and electronic products.
