Answer
For resin 3D print support marks, use 400 or 600, then refine with 800, 1000, and 1500.
Why it happens
Support points need gentle leveling and fine smoothing to avoid flattening small details.
Recommended grit
Use 400 or 600 for support marks, then 800, 1000, and 1500 for finer smoothing.
Wet or dry
Wet for fine smoothing after the print is fully cured.
Success check
Support marks are blended without losing surrounding detail.
What to do
- Make sure the resin print is fully cured.
- Level support marks with 400 or 600.
- Refine with 800 and 1000.
- Use 1500 for finer visible areas.
Avoid: Do not sand uncured resin dust without proper protection and dust control.
