How to Sand 3D Prints Smooth: Materials You’ll Need

Step 1: Safety First

Before you begin, put on a dust mask to protect yourself from inhaling particles. Ensure your workspace is well-ventilated.

Step 2: Prepare the 3D Print

Inspect your 3D print for any large imperfections that may require more aggressive sanding. Identify these areas as you’ll focus on them first.

Step 3: Start with Coarse Sandpaper

Use a coarse sandpaper, around 100-200 grit, to work on the identified problem areas. Make sure to apply consistent pressure and sand in a circular motion. This coarse sandpaper will remove the bulk of the imperfections.

Step 4: Move to Medium Grit

After working with the coarse sandpaper, switch to a medium-grit paper (around 400 grit). Again, sand in circular motions, applying even pressure. At this stage, your aim is to smooth out the areas you’ve sanded previously.

Step 5: Finish with Fine Grit

Lastly, use a fine grit sandpaper, like a 800-1000 grit, for the final touches. This will give your print a smooth finish. If you wish, you can also opt for wet sanding at this stage for an even smoother finish.

Step 6: Clean the Object

Once you’re satisfied with how smooth your 3D print is, use a clean, soft cloth to wipe away any residual dust or sanding particles.
