How do artists create lightweight, hollow structures in PVC animal sculptures?

Artists craft lightweight, hollow structures in PVC animal sculptures through a combination of innovative techniques and material choices. First, they often use thin PVC sheets or foam, which are easy to shape and inherently lightweight. By heating and molding the PVC, they can create smooth curves and intricate details without adding excess weight.

To achieve hollowness, artists employ methods like layering or constructing internal armatures. A common approach involves building a wire or mesh framework, then covering it with PVC layers. This not only reduces material usage but also ensures structural stability. Some artists even use inflatable molds or 3D-printed templates to guide the hollow design.

Additionally, strategic cutting and joining techniques, such as welding or adhesive bonding, help maintain the sculpture’s integrity while keeping it light. The result is a durable, visually striking piece that’s easy to transport and display. These methods highlight the blend of creativity and engineering in modern PVC sculpting.
