Use this checklist when you need a consistent visual quality-control routine for FDM or resin prints. It works best when the same operator, stand, and lighting setup are used regularly.

For setup context, review the 3D printing use case and the accessories page.

1. Prepare the part for inspection

Before evaluating the print, confirm:

  • The part is clean enough to reveal the real surface
  • Residual powder, resin, or dust is removed
  • The part is positioned stably
  • Lighting is adjusted to show edges and surface texture clearly
  • The area of interest is chosen before changing magnification

2. Check layer consistency

Inspect for:

  • Irregular layer spacing
  • Layer banding
  • Visible interruptions
  • Uneven fusion between layers
  • Abrupt changes after parameter transitions

3. Check for delamination and separation

Pay special attention to:

  • Corners
  • Thin walls
  • Stress-concentrated transitions
  • Holes and slots
  • Large flat surfaces with visible lifting or separation

4. Review edges, holes, and critical features

Inspect whether:

  • Edges are chipped or rounded unexpectedly
  • Holes show tearing, burrs, or deformation
  • Small features are incomplete
  • Support removal has damaged functional geometry

5. Review resin-specific or finishing defects

For resin parts or post-processed parts, verify:

  • Surface tackiness or residue
  • Pits or bubbles
  • Incomplete curing marks
  • Surface haze after cleaning
  • Scratches or swirl marks from finishing

6. Capture images of nonconformities

When a part is rejected or borderline, capture:

  • One contextual image of the part zone
  • One closer image of the defect
  • Another angle if reflections could mislead interpretation

This makes it easier to compare lots, explain rejection reasons, and tune process settings later with the software workflow.

7. Escalate when visual inspection is not enough

Escalate the part when:

  • The defect appears structural, not only superficial
  • The issue could affect fit or function
  • The part needs dimensional confirmation
  • You suspect internal problems not visible from the surface

Quick daily rule

Inspect the same way every time: stabilize the part, choose the area, compare surfaces under controlled light, and document only what is useful. Consistency is what turns visual inspection into quality control.
