What are the challenges of achieving deep undercuts in WPC sculptures?

Achieving deep undercuts in WPC (wood-plastic composite) sculptures presents several unique challenges. First, the material's fibrous nature can cause splintering or tearing during intricate carving, especially in delicate areas. Second, WPC's density and composition often lead to rapid tool wear, making it difficult to maintain precision over prolonged sculpting sessions. Additionally, the material's limited elasticity compared to pure wood or plastic restricts the depth and sharpness of undercuts without risking structural integrity. Design complexity also plays a role, as deep undercuts may compromise the sculpture's stability due to WPC's lower tensile strength. Finally, post-processing—such as sanding or finishing—becomes harder in deeply recessed areas, often requiring specialized tools or techniques. These factors collectively make deep undercuts a demanding aspect of WPC sculpting.
