How to choose the perfect resin for your miniatures 🧪

Finding the right resin is, without a doubt, the very first step towards giving your Warhammer 40k miniatures a professional finish. 🧐 Don't be fooled — not all resins are created equal; each one has its own role on the battlefield. Understanding what sets them apart is what separates a good print from a spectacular one.

The key is thinking about what you're actually printing. It's simple logic: you wouldn't give a stealthy scout the same armour as a Leman Russ tank. The same applies to resin. At Mr Resin we offer the best options for every project.

A resin for every type of troop

If you're printing something that needs to survive heavy use on the tabletop — like an imposing tank or a hulking Dreadnought — your best friend is an ABS-like resin. Its main advantage is its hardness and impact resistance. Trust me, nothing is worse than watching an accidental drop turn your war machine into a pile of broken pieces. 😭

On the other hand, if you're working on a Hero character — like a Space Marine Captain in full filigree-covered power armour — the game changes entirely. Here you need maximum precision. It's time to bring out the heavy artillery: 8K or even 14K resins, such as the Anycubic Texture resin, which is specifically formulated for miniatures. These are engineered to capture every last emblem, rivet, and battle scar with a sharpness that will leave your opponents speechless. 😮

Never underestimate the power of a quality resin. It's the foundation on which your masterpiece is built. A low-quality resin can swallow fine details, be far too brittle, and ultimately undo hours of careful paintwork.

The smart choice for every project

Beyond resins designed for detail or toughness, there are other options that will make your life a whole lot easier. Standard resins are great for printing large amounts of terrain pieces (ruins, barricades, etc.), where extreme detail isn't the priority, but a solid finish at a reasonable cost is.

On the other hand, if you want to simplify the messy cleaning process, water-washable resins are a game changer. They let you remove uncured resin residue with plain water, meaning you can say goodbye to isopropyl alcohol and cut down on fumes. They're ideal if your workspace is set up at home. If you want to dive deeper, check out our complete guide to 3D printing resins, where we break it all down.

To make things even clearer, we've put together a handy cheat sheet to help you decide.

Choosing the right resin from the start will save you time, money, and a whole lot of frustration. That way you can focus on what really matters: bringing your armies to life! 💥

From STL file to battle-ready miniature ⚙️

Once you have the perfect resin in hand, the real ritual of bringing your Warhammer 40k miniatures to life begins. The journey from opening an STL file to holding the finished model is where it all happens, and the small details make an enormous difference between success and frustration. Trust me, we've all been there. 😡➡️😁

The first step is preparing your model in slicer software such as Chitubox or Lychee. A golden tip that will save you a lot of headaches: orient your miniatures at roughly a 45-degree angle. Why? Simple — support marks left behind when removing supports will end up in less visible areas, like the back or under the arms, keeping those hard-earned front-facing details pristine.

Supports and exposure settings: the key to success

Dialling in your supports is a real art form — it's not just about slapping them on randomly. Each support serves a specific purpose, and knowing how to place them properly is a total game changer.

• Light supports: These are for the most delicate parts. Think thin swords, vehicle antennae, or the banners on your heroes. These supports ensure the most fragile details print correctly without leaving ugly marks.

• Medium supports: These are your workhorses. Use them for the main body of the miniature: torso, arms, legs... They provide the hold needed to stop the piece warping or detaching from the build plate mid-print, which is one of the most frustrating things that can happen.

Then there are exposure times. Think of them like baking a cake: too little time and the resin won't cure properly and the print fails. Too much, and the details get "burnt," losing definition and leaving your figure over-exposed and brittle. Every resin and every printer has its own ideal settings, so my recommendation is to always run a calibration test first — the Cones of Calibration is a classic — to nail it straight away.

Don't have an STL file to print? That's no excuse. There are huge communities of 3D artists creating incredible models. To get started, check out our list of the best websites to download free STL files and find your next troops.

As you can see, knowing the final purpose of your piece points you straight toward the right material choice — optimizing both costs and the final quality of your army.

Post-printing: the final stretch

Your miniature is printed! 🎉 But hold on, we're not done yet. Post-processing is just as important as the print itself — don't underestimate it.

First up is washing. Carefully remove the piece from the build plate and submerge it in isopropyl alcohol (IPA), or water if you're using a water-washable resin.

This is where a wash and cure station — like those from Anycubic or Elegoo — becomes an investment that pays for itself quickly. These machines agitate the cleaning liquid to reach every nook and cranny, then use UV light to cure the piece evenly. The final cure is what gives your miniature its maximum hardness and durability, leaving it ready for priming and painting.

Now you're ready for battle! ⚔️

Prime and paint your miniatures for a professional finish 🎨

A perfectly printed miniature is nothing more than a blank canvas. The real character of your army — that personality that makes it stand out on the tabletop — is built with brushes and paint. 🖌️

But be warned: the preparation process is just as critical as the painting itself. It's the foundation that ensures every layer of colour adheres properly and holds up through the toughest battles.

Once the piece is cured, the first step is removing the supports carefully. My advice is to use fine, precise flush cutters to avoid snapping off any detail. Then, using fine-grit sandpaper or a modelling file, gently smooth out any small marks left behind. A clean, smooth surface is essential for a flawless finish.

The Vallejo paint ecosystem

At Mr Resin, we fully trust the Vallejo paint ecosystem because it offers a solution for every need, from complete beginners to competition painters. Understanding each range is key to getting the best results in less time.

• Primer: This step is non-negotiable. A proper primer coat (black, white, or grey, depending on your desired finish) ensures the paint bonds firmly to resin prints.

• Game Color: This is your go-to range for base coats. It delivers outstanding pigmentation and a brush-ready consistency that gives you smooth, even coverage with vibrant, true-to-colour results.

• Xpress Color: Need to batch-paint a horde of Orks or a brood of Gaunts fast? Xpress Color is your secret weapon. These contrast-style paints flow into recesses to create natural shading and remain lighter on raised surfaces, giving you a base coat, shading, and a first highlight all in one pass. ⚡️

• Game Air: Formulated specifically for airbrushing, these paints are ideal for laying down base colours quickly across vehicles, monsters, or entire squads.

Preparation and priming account for 90% of a good paint job. Skipping these steps is like building a house without foundations — sooner or later, everything falls apart. Take your time here and your finished miniatures will show it.

Airbrushing for stunning, professional-quality finishes

The airbrush is no longer just a tool for professional painters — it has become an essential part of many hobbyists' setups. It's perfect for creating smooth blends on tank armour panels, object source lighting (OSL) effects on energy weapons, or simply priming and base coating entire armies quickly and evenly.

It's estimated that the Warhammer 40k hobby accounts for 1.2 million hours of assembly and painting time annually in Spain alone, with airbrushing making up 25% of that time. Using paints like Vallejo Game Air alongside a quality compressor streamlines the process and helps you achieve the high-end results you see at tournaments.

Mastering miniature painting techniques is a deeply rewarding journey. If you want to get the most out of these ranges, check out our guide on how to use Vallejo Game Color to paint your resin prints, packed with practical tips and step-by-step advice.

With the right tools and a little patience, your Warhammer 40k miniatures will go from simple gaming pieces to genuine display-worthy works of art. ✨

Bring your army to life with details and immersive bases 💥

This is where the real magic happens. Details are what separate a good army from one that stops people in their tracks. Those small, realistic touches are what transform your Warhammer 40K miniatures into true battle-hardened veterans.

One of the most powerful techniques for achieving this is weathering. The goal is to simulate the wear and tear that troops would suffer in active combat, making them look like they've survived countless engagements. But it's not just about making things look dirty for the sake of it. You need to think logically: where would mud accumulate after a firefight in the trenches? Which edges of the armour would take the most wear? 🤔

Weathering effects that make all the difference

Washes are your best starting point. A well-applied dark wash instantly brings out every recess in a piece of armour, creating incredible depth with minimal effort. A pot of Citadel Agrax Earthshade or a Vallejo dark wash will give you that built-up grime effect you're after.

But you can push things much further. Pigments take realism to another level entirely. You can simulate everything from desert dust to dried mud or rust with surprising ease. A touch of brown pigment on a marine's boots and it looks like he's just waded through a swamp. A little orange tone around a tank's exhausts and the rust effect becomes completely convincing.

A miniature tells a story, and the base is the stage where it unfolds. Never underestimate its power to set the scene and bring visual cohesion to your entire army.

Bases that tell their own story

The base is far more than a piece of plastic to keep your model upright. It's your chance to add context and reinforce the narrative. Is your army fighting across a post-apocalyptic wasteland, through an alien jungle, or among the ruins of a hive city? 🌍

Vallejo diorama texture pastes, available in the Mr Resin store, are perfect for this. They let you create everything from cracked desert terrain to dark swampland in minutes. Simply apply the paste, let it dry, then dry brush over it to make every detail pop.

To finish things off, add small scatter elements: a little static grass, some small stones, or debris (leftover plastic sprue offcuts work brilliantly for this). These small additions bring the base to life on its own terms.

At top-level competitive events, presentation matters — a lot. The numbers speak for themselves: around 70% of players are now using 3D-printed conversions and proxies. This has driven a 40% increase in searches for high-definition resins to produce miniatures and bases that genuinely impress tournament judges. You can read more about these trends at major Spanish tournament coverage.

Investing time in the details and bases doesn't just improve individual models — it elevates the entire presence of your army on the table. And trust me, that shows. 😉

Your Warhammer 40k 3D Printing Questions Answered

Here we'll tackle some of the most common questions that come up when you first catch the bug for printing your own Warhammer 40k miniatures. If something's still on your mind, don't hesitate to ask in our community! 💬

Is it legal to 3D print my own Warhammer 40k minis?

Ah, the million-dollar question. Let's set the record straight once and for all: printing community-created designs or proxies for personal use is something hobbyists do every single day. You're not doing anything wrong.

The key is to look for files from independent artists who create their own designs inspired by the universe, or even try your hand at sculpting your own. What you absolutely must avoid is distributing or selling copyright-protected designs. This hobby is about creativity and making it your own — not piracy. 🎨

What 3D printer do I need to get started?

If you want to capture the incredible level of detail that Warhammer 40k minis demand, there's no debate: you need a resin printer (SLA/DLP). The resolution they achieve is worlds apart from FDM filament printers when it comes to small, highly detailed pieces. Trust me, the difference is night and day.

For beginners, machines like the Elegoo Mars or the Anycubic Photon are absolute workhorses. They deliver incredible quality at a price that's no longer out of reach. In fact, at Mr Resin we offer starter bundles that have everything you need to dive in with confidence.

The upfront investment in a resin printer pays for itself surprisingly fast. Do the math: the cost of printing an entire squad is often less than buying a single official miniature. That gives you incredible freedom to experiment and grow your army without breaking the bank. 💸

Can I mix my 3D printed miniatures with official ones in my army?

Absolutely! In fact, it's one of the coolest things you can do. Plenty of players use 3D printing to create conversion bits: from custom weapons and alternate heads to personalised shoulder pads. It's the perfect way to give your official squads a truly unique look!

It's also a fantastic solution for fielding units that are long out of production, or for playtesting a new troop choice on the table before committing to the official box. Ultimately, combining the best of both worlds is what makes your army truly your own. 🤩
