bionic prosthetic arm 3d model

A sleek futuristic bionic prosthetic arm, full right arm, anatomically proportioned. Glossy matte-white armor shell panels covering the upper arm, forearm and hand, with exposed dark gunmetal-grey articulated joint mechanisms at the shoulder, elbow and wrist. Smooth flowing compound-curved surfaces with subtle muscle-like contours and clean panel seams between segments. Prominent circular dark pivot discs at the elbow and wrist. The hand has five fully articulated fingers, each with three segmented phalanges and visible knuckle joints, plus an opposable thumb; tendon-driven mechanical look with thin cables visible at the joints. Premium high-end cybernetic limb aesthetic, clean and seamless, like a flagship robotics prosthetic. Hard-surface modeling, subdivision -smooth shells, dark mechanical internals. Neutral studio lighting, plain background. Slightly bent elbow, fingers gently curled.
