Painting transforms 3D printed figurines from single-color prints into museum-quality display pieces. Even beginners can achieve impressive results with the right preparation, paints, and techniques.
Surface Preparation
Start by removing any support material and sanding rough spots with 220-grit sandpaper. For a smooth finish, apply filler primer spray — this fills layer lines and creates an ideal painting surface. Two light coats with sanding between them gives professional results.
Paint Selection
Acrylic paints are the standard for PLA figurines. They adhere well, dry quickly, and are available in hundreds of colors. Miniature painting brands like Citadel and Vallejo offer specialized formulations designed for detailed figure painting.
Basic Techniques
Base coating provides the foundation color. Dry brushing highlights raised details by lightly dragging a nearly-dry brush across surfaces. Washing — applying thinned dark paint into recesses — adds depth and shadow.
Advanced Methods
Airbrushing creates smooth gradients impossible with brushes. Zenithal priming (black base, white from above) creates natural-looking shadows before color is applied. Metallic pigment powders add realistic metal effects.
Sealing Your Work
Always seal painted figurines with a clear coat. Matte varnish gives a natural, non-reflective finish. Satin varnish provides subtle sheen. Gloss varnish creates a high-shine effect. Two thin coats protect your paintwork for years.
