If you’re looking to master how to sand detailed 3D prints, you’ve come to the right place. Sanding is an essential step in the post-processing of 3D prints, particularly those with intricate details. This comprehensive guide will take you through each step in the process, ensuring a smooth and polished finish.

How to Sand Detailed 3D Prints: Materials You’ll Need
- Sandpaper in various grits (120, 220, 400, 800)
- 3D printed object
- Soft cloth
- Water for wet sanding (optional)
- Mask and goggles for safety
Preparation
Before you dive into the sanding process, it’s crucial to prepare your workspace and the 3D printed object.
Workspace Setup
- Choose a well-ventilated area for sanding.
- Place a soft cloth or mat on the table to protect the 3D printed object from scratches.
- Wear a mask and goggles to protect yourself from dust and particles.
Step-by-Step Instructions: How to Sand Detailed 3D Prints
Here’s a step-by-step guide…
Step 1: Start with Coarse Sandpaper
Begin by using a piece of 120-grit sandpaper. Apply even pressure and make circular motions over the surface of the 3D print. Pay special attention to seams or lines.
Step 2: Progress to Finer Grits
After using the 120-grit sandpaper, move on to a 220-grit. Repeat the process and focus on smoothing out any remaining rough areas.
Step 3: Wet Sanding (Optional)
If you wish to wet sand, soak a piece of 400-grit sandpaper in water for a few minutes. Lightly sand the 3D print using the wet sandpaper. This will result in a smoother finish.
Step 4: Finishing Touches
For the final touch, use an 800-grit sandpaper to polish the surface. Be gentle and take your time to ensure you don’t ruin the details.
