Your 3D printed parts come off the build plate looking rough — visible layer lines, support marks, and surface inconsistencies that make them look unfinished. Manual sanding is slow, inconsistent, and doesn't scale. Chemical vapor smoothing only works on specific plastics and introduces safety and compliance complications. If you're producing 3D printed parts in any volume, you need a post-processing method that is repeatable, batch-friendly, and doesn't require skilled labor.
Choosing the wrong tumbling media costs you time, money, and surface quality. The wrong compound pairing can leave parts under-polished, over-abraded, or contaminated. This guide gives you a practical 5-step framework — no engineering degree required — so you can match media type, size, and compound to your specific part material and surface goal.
