Objective
Replace labor-intensive belt sanding with a more efficient, automated method for finishing cobalt chrome implants. Use slurry blasting and high-energy finishing to deburr and pre-polish “as-printed” surfaces, ensuring optimal surface preparation prior to final finishing or coating.

Solution
Bel Air developed a hybrid finishing process combining its Industrial 3D Print Smoother (slurry wet blasting) and Centrifugal Disc Finishing to replace the manual belt sanding process. This two-stage approach delivers consistent surface refinement across complex geometries, reducing cycle times and ensuring repeatable results. The slurry blasting stage gently removes residual powder and sharp edges, while the high-energy disc finisher pre-polishes the surface to a smooth, uniform finish—ideal for post-processing cobalt chrome 3D printed implants
