Best Paints for 3D Prints: Top Acrylic Sets Reviewed

Painting 3D prints is where a functional object becomes something worth keeping. The surface comes off the printer smooth enough to prime, but color, shading, and detail work are entirely on you , and the paint you choose determines how much control you actually have over the result. Acrylics dominate this space for good reason: water cleanup, fast drying, and a finish that bonds well to primed PLA, PETG, and resin alike.

Most of what follows covers acrylic sets and paint markers suited to brush painting, detail work, and broader coverage on printed parts. For primer selection, sanding sequences, and surface prep before any paint touches your print, the Post-Processing hub covers that ground in full.

Smallbudi 20 Colors Model Paint Set

Smallbudi 20 Colors Model Paint Set is a tightly scoped kit aimed squarely at modelers who want to start painting without sourcing brushes, thinner, and colors separately. The 20ml bottle size is practical , large enough to finish a small model several times over, small enough that you’re not committed to a color you end up disliking.

The included thinner matters more than it might seem. Owner reports indicate the paint consistency out of the bottle runs slightly thick for fine brush work, and having thinner on hand from the start rather than improvising with water makes a measurable difference in flow control. The three included brushes are basic, but they cover the range , a flat, a medium round, and a fine detail brush , and they’re serviceable for getting started.

For the scope of the kit, the color selection is reasonable. Twenty colors won’t cover every scheme, but they span primaries, metallics, and a few neutrals that do most of the work on sci-fi and fantasy miniatures. Owners building a first-time painting kit report the set holds up through multiple projects before colors need replacing.

55PCS Acrylic Paint Set of 36 Colors

The 55PCS Acrylic Paint Set](product:55pcs-acrylic-paint-set-of) makes a case on volume: 36 colors in 60ml bottles, 12 brushes, and a non-toxic formulation that suits general-purpose painting sessions without ventilation concerns. The 60ml bottle size is the standout spec here. For terrain work, large base coats, or any project where you’re covering significant surface area, having more paint per color reduces the anxiety of running low mid-session.

Pigment density is the honest trade-off with a budget set at this scale. Community feedback on r/3Dprinting and hobbyist forums generally places budget acrylic sets in the “adequate coverage in two coats” category rather than one-coat opacity. For most 3D print applications , especially on a primed surface , two thin coats is standard practice anyway, which takes some of the sting out of that limitation.

The 12-brush inclusion is a genuine convenience. Whether those brushes last through serious detail work is another question , most owners report rotating in a dedicated fine brush for anything under 1mm. But for base coating, drybrushing, and general coverage, the included set covers the workflow.

30 Colors Dual Tip Acrylic Paint Markers

Paint markers occupy a specific niche in 3D print finishing: they’re faster than brush painting for solid coverage on geometric surfaces, they don’t require palette setup or cleanup beyond capping the marker, and they travel easily. The 30 Colors Dual Tip Acrylic Paint Markers address the main limitation of single-tip markers , either too broad for detail or too fine for coverage , by including both a fine tip and a brush tip in each marker.

Owner reports describe the brush tip as genuinely flexible rather than a stiff felt nib, which makes it useful for curved surfaces and irregular geometry that comes off the printer in most organic prints. The fine tip holds a consistent line across surfaces that have been sanded to 400 grit or finer; on rougher surfaces, tip wear is faster.

The 30-color selection spans saturated brights and a solid neutral range. For highlight work on dark base coats or line detail on flat surfaces, markers at this color count give enough flexibility to work without mixing. Marker-based workflows suit prints where you want defined, clean color blocking rather than blended shading effects.

Shuttle Art Acrylic Paint 36 Colors

Shuttle Art Acrylic Paint 36 Colors is one of the more consistently mentioned starter kits in hobbyist 3D printing communities, primarily because it ships as a genuinely complete kit , 36 colors, brushes, and a palette , rather than paint alone. The palette inclusion is a small thing that matters: it makes thinning and color mixing a first-session option rather than something you improvise around a paper plate.

The 60ml bottles place this in the same volume tier as the 55PCS set, and the rich pigment claim holds up reasonably well in owner reports. Verified buyers across craft and modeling forums note that coverage on white-primed surfaces is solid at standard brush consistency. Color saturation is described as accurate to the swatch in most of the palette, with a few of the mid-range blues running slightly transparent , a known characteristic of phthalo-based pigments at budget price points, and manageable with a second coat.

For a modeler painting FDM prints, this kit hits the practical scope well. The 36-color range is wide enough that most base coat needs are covered, and the included brushes are adequate for anything except fine detail work. Owners consistently suggest adding a single quality size-0 or size-1 round brush for detail passes.

Artecho Acrylic Paint Markers 72 Colors

The case for Artecho Acrylic Paint Markers 72 Colors is color range. Seventy-two markers covers territory that most brush-painting sets don’t reach without mixing , specific earth tones, desaturated pastels, and expanded metallic options that matter on terrain pieces, dioramas, and character models where color accuracy to a reference is the goal.

The included carry bag is a functional detail for anyone who paints across locations or stores materials outside a dedicated workspace. Markers are generally more convenient to store than open bottles, and having a dedicated bag keeps tips capped and accessible. Owner reports note the bag holds the full 72-marker set without compression, which matters for tip longevity.

The dual tip design mirrors the 30-color set above, but the brush tips here receive more mixed feedback on wear rate. On smooth, primed resin prints, owners report consistent performance across extended use. On FDM prints with visible layer lines or post-sanding texture, tip wear is faster , the brush fibers catch on surface irregularities. The fine tip holds up better on rougher surfaces and is the stronger choice for detail lines on textured geometry.

Nicpro 30 Colors Model Paint Set

Nicpro 30 Colors Model Paint Set is the most directly targeted option here for miniature and model painting on 3D prints. The 30-color range in 20ml bottles is purpose-built for the hobby , the color selection skews toward the muted, layerable tones that work in miniature painting workflows rather than the saturated primaries that dominate craft-focused sets.

The airbrush compatibility note on the bottle is meaningful. Owner reports confirm the paint thins to a workable consistency for low-PSI airbrush use without additives beyond water, though dedicated airbrush medium improves flow further. For modelers who brush paint now and plan to add an airbrush later, a single consistent paint line across both methods simplifies the workflow considerably.

The 20ml bottle size limits total volume per color relative to the 60ml sets in this list, which matters more for terrain and large surface work than for miniatures. For figure painting, character models, and detailed 3D prints where coverage area is small and color variety is the priority, the Nicpro set’s scope is well-matched to the task. Owner consensus on hobbyist forums positions this as the strongest of the purpose-built modeling sets in the mid-range tier.

Buying Guide

Bottle Sets vs. Paint Markers

The format question comes first. Brush-applied bottle acrylics give more control over consistency , you thin to taste, mix on a palette, and can layer thin washes over a dried base. Paint markers trade that flexibility for speed and cleanliness. For prints with flat panels, geometric detail, or clean color blocking, markers are faster. For organic shapes, shading, blending, or any technique that requires paint on a palette, bottles are the right format. Most modelers end up using both: markers for broad, defined color areas and bottle acrylics for everything that needs precision.

Color Count and What You Actually Need

Larger sets look like better value until you account for which colors you actually use. Miniature and model painting consumes a narrow range heavily , off-whites, mid-grays, browns, and a few saturated accent colors , while many colors in a 36- or 72-piece set see minimal use. A more targeted 20- or 30-color set often covers the practical range without excess. The exception is terrain work, large-scale prints, or projects requiring specific color accuracy, where a wider palette earns its place. Assess the projects you’re painting before defaulting to the largest available set.

Bottle Size and Project Scale

Twenty milliliters per color suits miniature and figure painting well. For base coating large terrain pieces, structural components, or any print over roughly 15cm in its longest dimension, 60ml bottles reduce the likelihood of running out mid-session. The sets in this list split between 20ml (Smallbudi, Nicpro) and 60ml (55PCS, Shuttle Art) options , the right choice follows directly from the scale of what you’re painting. Mixing bottle sizes across a kit is a reasonable approach: large bottles for neutral base colors and small bottles for accent and detail colors.

Airbrush Compatibility

Not every acrylic in this list is suited to airbrush use without adjustment. The Nicpro set explicitly notes airbrush compatibility; the craft-focused sets (55PCS, Shuttle Art) are formulated for brush application and may require more thinning and flow improver to spray consistently. If airbrushing is part of your current or planned post-processing workflow, start with a set that documents compatibility rather than troubleshooting thinning ratios across a set of unknown-brand acrylics.

Surface Prep and Paint Adhesion

Paint adhesion on 3D prints depends almost entirely on surface preparation, not paint selection. Bare FDM PLA is slightly porous but benefits from a primer coat before acrylics for durability and even coverage. Resin prints require washing and full UV cure before any paint application , acrylics applied to uncured resin will lift. For either material, a light sanding pass to 220, 400 grit followed by a gray or white primer coat gives the acrylic something reliable to grip. The paints in this list will all perform better on a prepped surface than on bare plastic regardless of pigment quality.

Frequently Asked Questions

Do I need to prime 3D prints before painting?

Primer is not strictly mandatory, but it makes a consistent difference. On FDM prints, primer fills micro-layer-line texture and gives acrylics a surface they can grip uniformly. On resin prints, primer provides the same adhesion benefit and also masks any surface porosity from incomplete washing. Without primer, paint coverage tends to be uneven and more prone to chipping at edges and high points.

Can I use regular craft acrylics on 3D prints or do I need model-specific paint?

Craft acrylics like those in the 55PCS or Shuttle Art sets work on primed 3D prints. The practical difference between craft and model-specific acrylics is pigment density and color selection , model paints like the Nicpro set skew toward muted, layerable tones suited to miniature shading, while craft sets lean toward saturated primaries. For display models and terrain, craft acrylics are adequate. For detailed miniature work, the color range in purpose-built modeling sets is a meaningful advantage.

Are paint markers or brush-applied acrylics better for 3D prints?

Neither is universally better , the right choice depends on print geometry and painting technique. Markers work well on flat, geometric surfaces and sharp edges where clean color blocking is the goal. Brush-applied acrylics are more flexible for curved surfaces, shading, washing, and blending. The 30 Colors Dual Tip Acrylic Paint Markers and Artecho Acrylic Paint Markers 72 Colors both offer brush tips that cover some of the gap, but they don’t fully replicate palette-mixed acrylic control.

How do I keep acrylic paint from cracking or peeling on a 3D print?

The most common cause of cracking is paint applied too thick in a single coat. Thin coats , two to three passes rather than one heavy application , flex with the print surface and adhere more durably. A varnish topcoat after painting adds significant protection, particularly on parts that will be handled. Matte, satin, and gloss varnishes are all compatible with the acrylic sets in this list.

What is the difference between the Nicpro 30-color set and the Smallbudi 20-color set?

Both are purpose-built modeling sets in 20ml bottles, but the Nicpro set is airbrush-compatible and carries 10 additional colors, with a color selection that skews toward the tones used in miniature painting workflows. The Smallbudi set includes a thinner, which gives it an edge for users who want immediate brush-painting control out of the box without sourcing additional supplies. For dedicated miniature painting, Nicpro is the stronger tool. For a complete first kit with thinner included, Smallbudi covers the gap efficiently.
