What describes the additive sculpture technique?

The additive sculpture technique involves building up a form by progressively adding material, which distinguishes it from subtractive techniques where material is removed. In additive sculpture, artists work with various materials such as clay, wax, or even certain modern 3D manufacturing methods to gradually construct a sculpture from a smaller base. This allows for greater flexibility in shaping the form, as the artist can continually manipulate and refine the piece as it develops.

By focusing on the process of adding materials, artists can create intricate details and complex structures that may not be achievable through other methods. This technique can lead to dynamic and expressive works, reflecting the artist's vision as the piece evolves through layering and assembling different components.

The other options describe unrelated techniques or processes. Removing material is indicative of subtractive techniques, traditional tools do not specifically relate to the additive approach, and casting refers to a method of forming shapes through liquid material, which is distinct from adding solid materials together.
