To clean a 3D printed model, start by removing support structures or excess material with tweezers or a hobby knife, then use material-specific methods—like isopropyl alcohol for resin prints or compressed air for filament (PLA/ABS) prints—to clear residue.
- **Remove physical obstructions**: Gently take off supports or stringing with precision tools to avoid scratching the model. - **Use material-specific cleaning**: Resin prints need 90%+ isopropyl alcohol to dissolve uncured resin; filament prints benefit from compressed air to blow away fine debris.
For beginners, test cleaning solutions on a small area first and stick to basic tools to prevent damage.
