After the printing process, finishing a 3D-printed object is often the most exciting part. This is where paints and brushes come into play as indispensable accessories for 3D printing. With the right painting and surface treatment, you can give your 3D prints a unique and professional look. Paints and brushes allow you to highlight details, create textures, or give your models a realistic surface that transforms them from mere plastic objects into true works of art.
Whether you are a collector painting miniatures, an artist creating sculptures, or an engineer looking to visually enhance prototypes – choosing the right paints and brushes is essential to unlock the full potential of your 3D prints.
Top features when buying paints and brushes for 3D printing
-
Paint type
The choice of paint is crucial. Acrylic paints are best suited for 3D prints because they have high coverage, dry quickly, and adhere well to most 3D printing materials. -
Coverage
Make sure to choose paints with high coverage, especially for dark or translucent 3D prints. This saves time and effort as fewer layers are needed. -
Quick-drying
Fast-drying paints are ideal for applying multiple layers quickly without having to endure long drying times. -
Water-based or solvent-based paints
For most home projects, water-based acrylic paints are the easiest to handle and clean. Solvent-based paints offer a more durable surface but require more preparation and caution. -
Brush assortment
A versatile set of different brushes (fine, wide, round) is important to precisely paint both large areas and delicate details. -
Grip and ergonomics
Brushes with ergonomic handles allow longer working times without fatigue and provide better control for detailed work. -
Durability
Choose high-quality brushes that do not lose hairs quickly or lose their shape. Synthetic brushes are often more durable and offer good control. -
Compatibility with primer
Make sure the colors are compatible with the primer to achieve an even and durable surface. -
Finish options
From glossy to matte surfaces – choose colors that provide the desired finish to give your 3D print the final touch.
Advantages of using colors and brushes for 3D prints
-
Personalization
With colors and brushes, you can give your 3D prints a personal touch. This is especially useful when creating custom objects or gifts. -
Detail fidelity
Colors allow you to highlight the finest details that are not visible through printing alone. This is ideal for miniatures, models, and artworks. -
Surface finishing
With the right painting, you can smooth rough surfaces or mimic the look of materials like metal, wood, or stone. -
Enhanced aesthetics
An unpainted 3D print often looks plastic and raw. Colors and finishing can give a model a high-quality and professional appearance. -
Protective function
Some colors and coatings not only offer aesthetic benefits but also protect the print from wear, UV light, and moisture. -
Diverse design possibilities
With a wide color palette and various techniques, such as washes, drybrushing, or airbrushing, you can achieve almost any desired look. -
Correction options
Small printing errors, such as lines or unevenness, can be easily concealed by targeted painting without having to restart the print. -
Increased durability
A layer of paint can also increase the durability of your 3D print by acting as an additional protective layer, especially for mechanical parts or outdoor projects.
Common uses of paints and brushes in 3D printing
-
Miniatures and model building
Especially in tabletop gaming and model building, miniatures are painted in detail after printing to make them more realistic and individual. -
Prototype finishing
Engineers and designers use paints to visually enhance prototypes and achieve a more realistic representation of the final product. -
Artworks and sculptures
Artists use paints to give their 3D-printed sculptures a vibrant and expressive surface. -
Cosplay and props
3D-printed cosplay parts and movie props are often painted to make them look authentic and as close to the original as possible. -
Decorative objects
Decorative items printed for home use, such as vases or figurines, become real eye-catchers through paint and finishing.
Recommended accessories and complementary products
-
Primers
A good primer is the key to successful painting, as it smooths the surface and improves paint adhesion. Spray primers are especially convenient. -
Airbrush set
For larger projects or smooth color transitions, an airbrush set is excellent. It allows for even application of paint and saves time. -
Sealing varnishes
A sealing varnish (glossy or matte) protects the paint and ensures a durable finish. This is especially essential for models that are handled or moved regularly. -
Painting palettes and mixing tools
To mix colors and apply them precisely, palettes and mixing tools are helpful accessories. -
Brush cleaners
Special brush cleaners prevent bristles from hardening and extend the lifespan of your brushes.
FAQs
-
What type of paint is best suited for 3D prints?
Acrylic paints are the best choice as they adhere well to most 3D printing materials, dry quickly, and are easy to work with. -
Do I need to prime 3D prints before painting?
Yes, a primer provides a smooth surface and improves paint adhesion. It also prevents the paint from peeling off the print surface. -
Which brushes are best for details?
Fine, round synthetic brushes are excellent for delicate details and precise lines. -
Can I also spray 3D prints?
Yes, spray paints or airbrushes are ideal for painting large areas evenly or creating color gradients. -
How long does it take for paint on a 3D print to dry?
That depends on the type of paint. Acrylic paints usually dry within 10–30 minutes, while solvent-based paints may take longer. -
What surface treatment can I use after painting?
Sealing varnishes or clear coats protect the painted surface and give your model a glossy or matte finish.
