3D printing has revolutionized the world of art, design, and prototyping, allowing creators to produce intricate and personalized objects with ease. However, when it comes to finishing your 3D prints, the material and texture of the print can sometimes leave the surface looking unfinished. One of the most effective ways to enhance the appearance and longevity of your 3D prints is by using acrylic paint. Acrylic paints are versatile, easy to work with, and offer a wide range of finishes, making them perfect for a variety of 3D printing materials.
We’ll cover everything you need to know about the best acrylic paints for 3D prints, why they are ideal for this application, and how to properly paint your 3D creations for the best results. We will also answer some frequently asked questions to help you get started.
Why Use Acrylic Paint for 3D Prints?
Acrylic paint is the go-to option for most artists and hobbyists working with 3D prints. Here’s why:
1. Quick Drying
Acrylic paints dry faster than many other types of paint, which is beneficial for those who want to complete their project quickly. The quick drying time also means you can apply multiple coats of paint in a shorter period, making it easier to achieve the desired finish.
2. Easy to Use
Acrylic paint is water-based, making it easier to clean brushes, palettes, and other tools. It is also forgiving, allowing you to correct mistakes with ease. If you’re new to painting 3D prints, acrylic paint is a great choice because of its user-friendliness.
3. Durability
Acrylic paints create a hard, durable finish when applied to 3D prints. They are resistant to cracking and fading, which is important for items that will be handled frequently, like figurines, toys, or models.
4. Versatility
Acrylic paint can be used on a wide range of materials that are common in 3D printing, such as PLA, ABS, PETG, and resin. It adheres well to these surfaces without the need for special primers or treatments, making it a convenient option.
5. Variety of Finishes
From matte to glossy, satin to metallic, acrylic paints are available in a wide variety of finishes. You can achieve your preferred aesthetic by selecting the right type of acrylic paint for your project.
6. Non-toxic
Since acrylic paint is water-based, it is generally non-toxic, making it safer to use, especially in a well-ventilated area. This is important if you are painting in small spaces or if children are involved in the process.

How to Paint 3D Prints with Acrylic Paint
Painting your 3D prints can be a fun and rewarding process. Here’s a step-by-step guide to ensure you achieve a smooth, durable finish:
Step 1: Prepare Your Print
Before painting, ensure your 3D print is clean and free from any dust or oil. Use a mild soap solution or isopropyl alcohol to clean the surface. If your print has visible layer lines or imperfections, sand the surface lightly with fine-grit sandpaper to smooth it out.
Step 2: Prime the Print (Optional)
Priming is an optional but recommended step, especially if you’re working with an unpainted 3D print. Apply a thin layer of primer to help the paint adhere better and create a smoother finish. Use a spray primer designed for plastics or 3D prints for the best results.
Step 3: Choose the Right Paint and Apply the First Coat
Select the acrylic paint that suits your project. Apply the first coat of paint using a paintbrush, airbrush, or spray. Use thin layers to prevent the paint from pooling or dripping. Let each coat dry fully before applying additional layers.
Step 4: Add Details
If you’re working on a detailed print, you may want to use a fine-tipped brush to add accents, highlights, or shadows. Acrylic paint is great for layering and blending, so you can build up intricate details.
Step 5: Seal the Paint (Optional)
To protect your painted 3D print, consider applying a clear acrylic sealant or varnish. This will help preserve the paint job and provide an extra layer of protection against wear and tear.
