Best Accessories for Finishing 3D Printed Models
In the world of 3D printing, the possibilities are virtually limitless. However, once a model is printed, the finishing touches can make all the difference. To enhance the aesthetic appeal and functional properties of 3D printed models, using the right accessories is essential. Here’s a guide to the best accessories for finishing 3D printed models.
1. Sanding Tools
Sanding is crucial for achieving a smooth surface on 3D printed models. Start with coarse grit sandpaper (around 80-120 grit) to remove any layer lines and imperfections. Gradually move to finer grits (up to 400 grit or higher) for a polished finish. Additionally, sanding sponges can help reach curved surfaces effectively.
2. Primers
Applying a primer is an important step before painting. Primers can fill in small gaps and create a uniform surface for paint adherence. Look for a primer specifically designed for plastics to ensure compatibility with your 3D printed materials. An aerosol primer can provide an even application and save time.
3. Paints
The choice of paint can dramatically affect the final look of your model. Acrylic paints are a popular choice due to their ease of use and quick drying time. For high detail models, consider using airbrush paints, which allow you to achieve fine detail and smoother finishes. Don't forget to use paint specifically designed for plastics to avoid adhesion issues.
4. Clear Coats
A clear coat is essential for protecting your finished model. It adds a layer of protection against scratches and UV damage while enhancing the overall appearance. Matte, satin, and glossy finishes are available, so choose one that best suits your aesthetic preferences. Spray-on clear coats are typically easier to apply for an even finish.
5. Filling Putty
For larger gaps and imperfections, filling putty can be a lifesaver. This material is perfect for smoothing out uneven surfaces. Once applied, sand it down to blend it with the model seamlessly before proceeding with priming and painting.
6. Adhesives
When assembling multiple parts of a 3D printed model, choosing the right adhesive is crucial. Cyanoacrylate (super glue) is commonly used for its fast bond and simplicity. For a more robust connection, consider using epoxy adhesives. Ensure that the adhesive is suitable for the specific type of filament used in your prints.
7. Tools for Details
To take your finishing to the next level, use detail tools like hobby knives, sculpting tools, and tweezers. These tools allow you to trim excess filament, scrape off supports, and refine small features on your model. The addition of tiny parts, like decals or tiny lights, can also enhance the realism of your finished piece.
8. Supports and Display Stands
Lastly, don’t forget about supporting your model. A good display stand showcases your work and prevents it from being damaged. Whether you’re displaying it in your home or preparing it for a trade show, a sturdy model stand can keep it secure and elevate its visual impact.
In conclusion, the finishing process of 3D printed models is just as important as the printing itself. By using these accessories effectively, you can transform your 3D prints from basic to breathtakingly beautiful. Experiment with different techniques and products to find what works best for your specific projects and make your models truly stand out.
