1. Ultramarines – The Dynasty of Blue Space

We're kicking things off with the sons of Guilliman! The Ultramarines are, without question, the archetypal Space Marines Chapter. They're Games Workshop's poster boys and the benchmark against which almost every other chapter is measured. Founded by Primarch Roboute Guilliman, their home world is Macragge — a beacon of order and civilisation.

Their greatest legacy is the Codex Astartes, the tactical bible that most chapters follow to the letter. This devotion to doctrine, discipline, and martial excellence makes them a balanced and versatile army on the tabletop. They don't excel at any one thing, but they're solid across the board — which makes them perfect for any type of mission. Their iconic blue, white, and gold colour scheme is instantly recognisable and a painting challenge that's absolutely worth taking on.

Tips for Your Ultramarines

• Printing and Materials: To capture all the fine details on their ornate armour — like the laurels and the iconic "Ultima" (Ʊ) symbol — I recommend using a high-definition resin. Precision is everything when it comes to making those emblems and gold trim look sharp.
• Painting: Blue is the star of the show here. In my experience, Vallejo Game Color Ultramarine Blue (72.022) is a go-to base coat that never disappoints. For the gold details, AK Interactive True Metallic Metal or Vallejo Metal Color paints will give you a bright, professional metallic finish.

2. Blood Angels - The Winged Warriors

Now let's talk about one of the most tragic and ferocious legions in the setting: the Blood Angels. Founded by Primarch Sanguinius, the glorious angel, these warriors are the embodiment of duality. On one hand, they are artists and creators of unmatched martial beauty; on the other, they carry a terrible genetic curse — the Black Rage and the Red Thirst — that drives them toward an uncontrollable killing fury.

Their speciality is fast assault and devastating close-combat warfare. The red power armour and golden details — often adorned with wing iconography and blood drop motifs — make them visually stunning on the tabletop. Their aggressive playstyle and rich lore make the Blood Angels one of the most beloved Space Marine chapters in the hobby. If you're looking for an army that blends elegance, brutality, and a compelling narrative, the sons of Sanguinius are the chapter for you.

Tips for Your Blood Angels

• Printing and Materials: Blood Angels feature a huge amount of fine detail — wings, gemstones, and intricate filigree. For delicate pieces like Sanguinary Guard wings, I'd recommend a resin with some flexibility to avoid breakage. A standard or ABS-like resin will work great for the main body components.
• Painting: Deep blood red is the star here. To achieve smooth gradients on the armour, I'd suggest using an airbrush with Vallejo Game Air Blood Red (72.710). For the gold ornaments that define their iconic look, Vallejo Metal Color paints will give you that rich, gleaming finish you're after.

3. Space Wolves - The Arctic Hunters

By Russ and the Allfather! We leave strict doctrine behind and venture into the frozen wastes of Fenris with the Space Wolves. These fierce sons of Leman Russ stand as the antithesis of the rigid Codex Astartes structure. Their tribal culture and warrior spirit make them one of the most charismatic chapters in the game. Their organisation is built around Great Companies led by a Wolf Lord, with warriors ranging from the headstrong Blood Claws all the way up to the veteran Grey Hunters.

On the battlefield, their ferocity is legendary. They specialise in assault and close combat, unleashing a storm of frost axes and chainswords. Their savage aesthetic — packed with furs, runes, and wolf totems — makes for an incredibly rewarding customisation and painting project. If you're into space vikings with a serious attitude problem, the Space Wolves are your chapter.

Tips for Your Space Wolves

• Printing and Materials: For their armour, which combines smooth surfaces with runic details and furs, a standard resin with a good finish will give you a perfect base. You don't need extreme definition for the plates, but you do need enough for the textures to stand out. If you're looking for a solid starting point, check out our guide on how to 3D print miniatures to get the best results.
• Painting: For the iconic blue-grey of their armour, my personal recommendation is Vallejo Game Color Wolf Grey (72.047). This shade has just the right cold undertone to evoke the arctic atmosphere of Fenris. For the intricate facial tattoos and runes, nothing beats an Artis Opus Series S brush with an extra-fine tip. The precision it offers lets you paint crisp, clean lines.

4. Dark Angels - Keepers of the Secret

Next up is the First Chapter of them all — the enigmatic sons of Lion El'Jonson. The Dark Angels are one of the oldest and most mysterious legions in the Imperium. Their history is defined by a dark obsession: hunting the Fallen, those brothers who betrayed their Primarch during the Horus Heresy. This relentless pursuit shapes their entire existence, blending near-fanatical monastic discipline with a ferocity in combat that few can match.

Their organisation is divided into specialist companies such as the Deathwing — made up of elite Terminators clad in bone-white armour — and the Ravenwing, masters of fast assault. This secrecy and specialisation makes them one of the most compelling Space Marines chapters, with a dark green, bone, and black colour scheme that commands respect.

Tips for Your Dark Angels

• Printing and Materials: Given that many painters like to experiment with this chapter — testing different shades of green, battle damage effects, and so on — I'd recommend using a water-washable resin. It makes clean-up much easier and allows for quick touch-ups without the hassle of alcohols, making it ideal for experimenting.
• Painting: Dark green is the star of the show. For me, Vallejo Game Color Dark Green (72.028) is an excellent base. I've had great results applying heavily thinned black washes into the recesses, creating deep contrast. To capture the mystery surrounding them, try Vallejo's technical layer effects — things like subtle mist or grime work really well.

5. Imperial Fists - Masters of Siege Warfare

Now we come to the sons of Rogal Dorn — the stoic defenders of Terra. The Imperial Fists are the Imperium's foremost builders and siege warriors, masters of fortification and war of attrition. Their most defining trait is their stubbornness and ironclad discipline. They don't retreat, they don't surrender — they simply hold the line, turning any position into an impregnable stronghold.

On the tabletop, this makes them incredibly resilient and deadly at ranged combat. Their iconic bright yellow color scheme with red and black details is one of the most striking and challenging to paint, but the end result is a miniature that truly stands out. They are, without doubt, one of the most iconic Space Marines chapters.

Tips for Your Imperial Fists

• Printing and Materials: To achieve a smooth, flawless surface for applying even coats of paint, I recommend using a standard 3D resin that offers a great finish. The key with yellow is starting with a perfectly clean base so the color comes out consistent and uniform.
• Paint: Painting yellow is a true art form. My advice is to apply Vallejo Game Color Sun Yellow (72.006) in several thin layers over a white or bone primer. For the architectural ornamentation and gold details, the AK Interactive True Metallic Metal range will give you that professional metallic finish they need.

6. Iron Hands - The Servants of the Machine

"The flesh is weak!" This is the creed of the relentless Iron Hands. Led by their tragic Primarch, Ferrus Manus, this is one of the Space Marines chapters that has taken logic and the rejection of weakness to its ultimate conclusion. For them, the purity of the machine is superior to the fragility of flesh. This translates into an overwhelming number of bionic augmentations, to the point where many veterans are more metal than man.

On the battlefield, the Iron Hands are specialists in mechanized warfare. They typically field a massive number of tanks and dreadnoughts, backed by devastating firepower. They are methodical, cold, and calculating. Their black color scheme with silver and white details is understated but highly effective.

Tips for Your Iron Hands

• Printing and Materials: To represent the Iron Hands' extensive mechanical and cybernetic components, I recommend using an ABS-like resin. Its durability is ideal for creating robust parts like bionic arms or gun barrels that won't break easily.
• Paint: Black is the foundation, but metal is the real star. In my experience, the AK Interactive True Metallic Metal range is fantastic for achieving a realistic and vibrant silver on bionic arms and armor trims. To bring the eye lenses to life, a touch of Vallejo FX Red (72.130) technical effect will create a spectacular contrast of an active lens glowing in the dark.

7. Salamanders - The Guardians of Fire

Vulkan's fire burns eternal! The Salamanders are one of the most unique chapters, not only for their mastery of melta weapons and flamers, but for their deep humanitarian values. Hailing from the volcanic world of Nocturne, the sons of Primarch Vulkan live among the people they swore to protect. Their creed is built on sacrifice and an unwavering compassion for the civilians of the Imperium, making them true guardians.

On the tabletop, they specialize in close-range combat, where their thermal weapons can reduce even the most heavily armored enemies to ash. Their vibrant green, black, and fire-and-gold color scheme is spectacular and makes for a highly rewarding painting project.

Tips for Your Salamanders

• Printing and Materials: To make the dragon scales, ornate hammers, and flame motifs on their armour stand out with maximum definition, I recommend a high-definition resin. Every detail matters when capturing the handcrafted essence of this chapter.
• Painting: Green is the star of the show. For the base coat, Vallejo Game Color Goblin Green (72.030) is an excellent starting point. For dramatic contrast, use pure black on the shoulder pads and add orange or yellow details to simulate fire. Orange and red technical effects work perfectly for bringing the muzzles of their melta weapons to life.

8. Raven Guard - Masters of Stealth

Now we turn to the sons of Corax, the lords of guerrilla warfare. The Raven Guard are the undisputed experts in stealth, infiltration, and lightning strikes. Hailing from the bleak world of Deliverance, this is one of the Space Marine chapters that has perfected the art of appearing where the enemy least expects it, striking with lethal precision, and vanishing without a trace. They are ghosts on the battlefield.

Their combat style favours sabotage and surgical strikes. This makes them a fascinating army, where specialist infiltration units can disrupt your opponent's plans from the very first turn. Their jet-black colour scheme with white and red accents is elegant and brooding — a real challenge to pull off without it looking flat.

Tips for Your Raven Guard

• Printing and Materials: For prototyping different dynamic stealth poses, I recommend a water-washable resin. The easy clean-up lets you experiment with poses and make adjustments without any hassle. Flexibility during assembly is key to capturing their essence.
• Painting: Black is the star here, but it needs to be a well-executed black. In my experience, starting from a base of Vallejo Game Color Black Grey (72.051) and building up subtle highlights with lighter greys creates incredible depth. For the delicate raven symbols on the shoulder pads, Artis Opus detail brushes are an absolute game-changer.

9. White Scars - Riders of the Sky

Get ready for lightning speed! The White Scars are the nomadic sons of Primarch Jaghatai Khan. Hailing from the steppe world of Chogoris, their culture draws inspiration from the warrior tribes of history. They are the undisputed masters of mechanised combat and lightning raids — a white tide of steel that strikes the enemy at their weakest point and disappears before they can respond.

Forget static battle lines; the White Scars live and die on their bikes and Land Speeders. Their combat doctrine is built on rapid penetration and relentless harassment. On the tabletop, this translates into an incredibly mobile and lethal army. Their pure white colour scheme with red and black accents is as elegant as it is challenging to paint.

Tips for Your White Scars

• Printing and Materials: For the smooth, aerodynamic surfaces of their bikes and armour, an ABS-like resin will give you a perfect finish. You don't need extreme detail resolution here — what you need is a solid base that makes for a clean paint job.
• Painting: White is the big challenge. My trick is using Vallejo Game Color White (72.001), but applying it in very, very thin coats to build up smooth coverage. For the contrast that defines the geometry, nothing beats Vallejo Model Color Black (70.950) in the recesses and technical details. That contrast really makes the white pop.

10. Black Templars – The Obsessed Crusaders

No pity! No respite! No forgiveness! The Black Templars are the embodiment of religious fervour and martial fury. As a successor chapter to the Imperial Fists, these warrior-monks led by Sigismund have abandoned the Codex Astartes to wage eternal Crusades. Their sole purpose is to purge the heretic, the mutant, and the alien with fanatical devotion.

Their combat style is direct and brutal — they hurl themselves into the heart of battle, chainswords screaming. They specialise in close-quarters combat, where their unbreakable faith becomes a lethal weapon. Their Gothic aesthetic, complete with tabards, chains, and crosses, makes them an incredibly rewarding painting project.

Tips for Your Black Templars

• Printing and Materials: Their ornate weapons and reliquaries need durability. I recommend using an ABS-like resin to give your pieces the toughness to survive an accidental tumble off the table.
• Painting: Black is the foundation, but the trick lies in contrast. A deep black like Vallejo Game Color Black (72.051) is an excellent starting point. For the iconic crosses and pauldron trim, crisp white is key. For chains and weapons, the AK Interactive True Metal range in silver tones will give you that metallic, austere shine that defines them.

11. Deathwing (Dark Angels Veterans) – The Elite of the Shadows

When it comes to battle-hardened veterans, the Deathwing demand a mention. This is the First Company of the Dark Angels, composed entirely of elite warriors clad in imposing Terminator Armour. They are the vanguard of the Inner Circle, and their primary mission is hunting the Fallen — those brothers who betrayed the chapter ten thousand years ago.

Unlike the rest of the chapter, which wears dark green, the Deathwing wear armour in a distinctive bone colour. On the battlefield, they are a relentless and near-indestructible force, specialising in Deep Strike teleport assaults that sow panic deep within enemy lines. Their iconography is steeped in arcane symbolism, making them a fascinating project for any fan of Space Marine chapters with a darker edge.

Tips for Your Deathwing

• Printing and Materials: Terminator Armour features incredibly complex details. To get every one of those details looking crisp and sharp, I recommend using a high-resolution high-definition resin. Precision is essential if you want these miniatures to feel truly imposing.
• Painting: Bone white is the star of the show. A solid basecoat is Vallejo Game Color Bonewhite (72.034), over which you can apply shading washes like Agrax Earthshade. For metallic details, combining black with a metallic silver creates a dramatic contrast. For heraldic symbols, detail brushes like those from Artis Opus are an investment that will make your life a whole lot easier.

12. Invictus Guardians (Guard of the Indomitus) – Modern Primaris Guardians

Next up on our list are the newcomers — the new generation of Space Marines! The Invictus Guardians, also known as the Guard of the Indomitus, represent the future of the Adeptus Astartes. Created by Belisarius Cawl, these warriors are Primaris Space Marines: larger, stronger, and more resilient than their predecessors. Armed with cutting-edge technology such as Mk. X Tacticus armour, they are the Imperium's answer to an ever-darkening galaxy.

Their doctrine was forged during the Indomitus Crusade, making them pragmatic and adaptable. They are less bound by ancient traditions, which makes them a versatile and modern fighting force. Their aesthetic — often featuring dark metallic blues and glowing energy details — reflects their technological origins. They are one of the most recent and visually striking Space Marine chapters in the hobby.

Tips for Your Invictus Guardians

• Printing & Materials: To get those large flat panels and sharp armour edges looking crisp on your Primaris models, along with the fine rifle details, I'd highly recommend using a high-definition resin like Anycubic's 7.5K range. The resolution really makes a difference when it comes to getting each armour panel looking clean and defined.
• Painting: For that sleek modern metallic blue effect, here's a tip that works brilliantly for me: start with a bright silver base coat, then apply a thin layer of Vallejo Game Air Dark Blue (72.722) over the top. This creates an incredible sense of depth.For energy effects on weapons and visors, technical paints like Vallejo Technical Gold (73.201) or a deep electric blue will give that advanced Primaris technology feel.

Comparison of 12 Space Marines Chapters

Conclusion

And there we have it, makers! Quite the journey across the 41st Millennium, right? We've taken a deep dive into 12 of the most iconic Space Marines chapters, breaking down everything from their lore to practical tips so your 3D printers and brushes can work their magic. My goal was to give you a complete roadmap so you can choose your next army with both your head and your heart.

I hope you now have a much clearer picture of what this universe has to offer. From the discipline of the Ultramarines to the fury of the Blood Angels, every chapter is a world unto itself. And the best part is that, thanks to 3D printing, there are no limits to your creativity.

What fascinates me most is watching an STL file become something you can actually hold in your hands. That's why I've put together some specific tips for you:

• Resin choice is everything: Printing a sturdy tank (where an ABS-like resin would be my go-to) is a completely different challenge from printing a highly detailed character, where a high-definition resin will capture every last detail.
• Preparation makes all the difference: A solid primer coat is 90% of a great paint job. Trust me — taking the time to get this step right will save you a world of headaches later.
• Painting is storytelling: Subtle battle damage and weathering powders tell a story without a single word.

Remember, there's no "right" choice. The best chapter is the one whose story resonates with you and whose colour scheme makes you want to pick up a brush.

In my experience, the projects I've enjoyed most are the ones where I felt a genuine personal connection with the army. Don't just follow the meta — choose the legion that truly inspires you. The finished result will reflect that dedication.

This Space Marines chapter guide is just the starting point. I encourage you to keep exploring, experiment with your printers, and find your own style. I've got you covered!
