Abstract sculpture involves crafting a shape or form using a combination of lines or a simple shape, without the use of colour.
In the early 20th century, avant-garde sculptors moved away from realistic representation to explore abstraction. They aimed to express life's realities through forms rather than replicating the visible world. Abstract sculpture became a fertile ground for experimenting with shape, proportion, and techniques, including unconventional methods like industrial manufacturing, plastic moulds, and 3D printing. Modern abstract sculpture includes Concrete Art's precise forms, Minimalist sculptures with strict geometry, and Kinetic Sculpture embodying movement and physical forces.
