💡 QC Insight for Buyers

In 3D printing, “support removal” is often treated as an afterthought, but it’s a critical step that determines the final quality of your product. If the supplier doesn’t have a standardized post-processing checklist, you can expect inconsistent results — some units will have sharp burrs, others won’t.

When briefing your supplier, don’t just ask them to “remove supports.” Explicitly request a post-processing quality control step where each unit is inspected for sharp edges and burrs. This simple addition to their workflow eliminates the risk of customer complaints and returns — one of the most common and preventable issues we catch during inspections.
