How to speed up repair in sanding for 3D models?

To speed up sanding repairs for 3D models, prioritize tool matching, grit progression, stabilization, and detail tools—key steps to save time while fixing flaws. Match tools to your model’s material: Electric sanders work fast on large plastic parts, while sanding sticks suit resin or small sections. Use grit progression: Start with coarse (120–240) to remove layer lines/support marks quickly, then switch to finer (400–800) for smoothing—don’t waste time fine-sanding rough areas early. Stabilize the model with a clamp/vise: This prevents accidental damage and rework, cutting down on repeat steps. For small details, use sanding sponges or sandpaper-wrapped toothpicks: They fix tiny blemishes fast without tool changes.
