Product Overview: This premium 3D digital asset is a highly detailed, performance-accurate portrait bust sculpture of Michael Jackson during his peak live concert era. Meticulously engineered for the luxury jewelry sector, the model captures a highly expressive performance expression. Key structural highlights include realistic loose curls falling over the facial profile, a stage-microphone held firmly to the mouth, and an exceptionally detailed multi-layered costume consisting of a buckle-strapped pebble-grain leather jacket, a graphic inner t-shirt, a classic hoop earring, and a heavily buckled performance wrist glove.

INDUSTRIAL MANUFACTURING AND PRODUCTION GUIDE3D Printing Parameters: Recommended for use with high-precision industrial stereolithography (SLA/DLP) castable resins at a layer thickness of 15 microns. Due to the high details compressed into the 27.60 mm boundary frame as visualized in image_584ac8.png, maximum machine resolution is critical to cleanly execute the leather jacket textures, miniature buckles, and fine hair curls without losing definition.

Metal Casting Protocol: Engineered for vacuum pressure investment casting procedures. Given the lean and balanced 760 mm3 mass distribution, place the primary feeding sprue at the widest area of the lower chest boundary to guarantee a clean, unhindered upward fluid path into the microphone arm assembly and facial features.

Professional Bench Finishing Recommendations:

Mirror-Polishing: Apply a high-luster polish to the prominent anatomical planes of the face, jawline, neck, hand, and the smooth raised edges of the jacket metal buckles.

Antiquing/Oxidation Treatment: Apply a dark localized patina inside the deep recesses of the matted hair curls, the gaps between the microphone grille lines, and the pebble-grain fabric matrix to establish stark 3D shadow contrast.

Matte/Satin Contrast: Apply a light sandblast or satin-wheel brush finish to the inner t-shirt cloth areas to let the highly polished face and metal details detach visually for a premium multi-textured appearance.
