Surface Preparation and Priming Methods
You’ll need to choose the right primer and determine whether sanding is necessary before painting your 3D printed miniatures.
Rattle can primers like Rustoleum greatly improve paint adhesion and create a durable finish, while matte PLA filaments often don’t require sanding due to their smoother surface texture.
Your primer selection should consider both the material you’re working with and the painting techniques you’ll use, as a strong colored undercoat enhances dry-brushing effects and overall depth.
Primer Selection Techniques
While many painters rush straight to applying color, proper primer selection and surface preparation form the foundation of any successful miniature paint job.
When painting 3D printed models, you’ll want to use a strong primer like Rustoleum to guarantee superior paint adhesion and durability. Your primer selection techniques should prioritize black undercoats, which create natural depth and enhance contrast for subsequent dry-brushing layers.
Rattle can primers offer the most convenient coverage for detailed miniatures.
Before applying any primer, clean your model thoroughly and sand rough areas to improve finish quality. Always test your chosen primer on a small section first to verify compatibility.
This preparation step prevents paint failure and guarantees your miniature painting project achieves professional-quality results.
Sanding Requirements Guidelines
Building on proper primer selection, understanding when and how to sand your 3D printed miniatures determines whether your paint job looks amateur or professional. You’ll need to assess your print’s surface quality before deciding on sanding requirements.
| Print Quality | Sanding Needed | Grit Recommendation |
|---|---|---|
| Rough/Layer Lines | Yes | 220-400 grit |
| Smooth PLA | Light sanding | 400-600 grit |
| Matte Filament | No | N/A |
Start with higher grit numbers for delicate details to avoid removing fine features. Always clean dust and residue after sanding before applying primer. For most PLA miniatures, light sanding with 400-grit sandpaper improves paint adhesion considerably. Skip sanding entirely if you’re using matte filaments, as their natural texture provides excellent paint grip without additional preparation.
Essential Tools and Equipment for Miniature Painting
Having the right tools makes all the difference between frustrating painting sessions and enjoyable ones that produce professional-looking results.
You’ll need various paintbrush sizes to handle intricate details and broader coverage areas effectively. A mixing palette lets you create custom colors and control how the best paint appears on your miniatures.
Keep a water container nearby for rinsing brushes between applications, preventing paint from drying on bristles and maintaining brush quality.
Don’t forget preparation tools like cutting implements, files, and sandpaper to smooth 3D print surfaces for better paint adhesion.
Set up adequate lighting and ventilation in your workspace. Good lighting helps you see fine details clearly, while proper ventilation guarantees safe use of paints and sealants during extended painting sessions.
