Walk into any games night and you’ll find two tribes of miniatures sharing the table: grey plastic warriors clipped from sprues, and crisp resin models fresh from a 3D printer. Both can look stunning once painted, but they behave very differently on the workbench and at the table. If you’re wondering which is right for your next army, adventuring party or display piece, this guide to resin vs plastic miniatures breaks down the real-world differences, without the forum flame wars.
When most hobbyists say plastic miniatures, they mean injection-moulded polystyrene kits – the multi-part models you snip from a frame (or sprue) and glue together. Big wargaming publishers have built their ranges on this method because a steel mould can churn out thousands of identical kits.
Resin miniatures come in two flavours. Traditional cast resin is poured into silicone moulds, while modern resin minis – like everything in our 3D printed miniatures collection – are printed layer by layer from liquid photopolymer resin that hardens under UV light. Printing needs no expensive moulds, which is why independent sculptors and small studios can release such wildly creative ranges every month.
Resin printers work in extremely thin layers, so they capture tiny features that injection moulding struggles with: individual strands of hair, chainmail links, delicate filigree on a sword hilt, the scales on a dragon’s wing. Because there’s no mould to pull the model out of, sculptors can also design deep undercuts and dramatic, overlapping poses that would be impossible to cast in a two-part steel tool.
If you’d like a deeper technical look at why resin printing beats filament printing for miniatures, JLCPCB’s 3D printing team has a handy explainer on resin vs FDM printing for miniatures.
Plastic kits are no slouch, mind you – modern sprues are beautifully engineered – but detail is always a balance between what the sculptor wants and what the mould can release. That’s why plastic models are often split into many parts, and why you’ll find mould lines along the seams.
Polystyrene has a little flex to it. Knock a plastic spearman off the table and he’ll usually survive with nothing worse than a chipped paint job. Cured resin is harder and more rigid, which is what lets it hold such sharp detail – but it also means very thin parts (spear shafts, antennae, wand tips) can snap if dropped or squeezed.
A few habits keep resin minis safe:
Treat them like a well-loved spellbook rather than a dice bag, and resin models will last for years of campaigns.
Here’s the difference that catches out most newcomers. Plastic cement works by slightly melting polystyrene so two parts weld together. On resin it does nothing at all. For resin you need superglue (cyanoacrylate), ideally a gel version for gap filling, and for larger joints a two-part epoxy or a pin made from a short length of brass rod. Scale Model Shop has a clear rundown of the best glues for resin kits if you want to compare options.
Plastic kits ask for more clipping, mould-line scraping and assembly time. Goonhammer’s Hobby 101 guide to miniature assembly walks through the whole process nicely. Many 3D printed resin minis, by contrast, arrive in one piece or just a few parts, so you can go from box to primer much faster.
Clip, scrape mould lines, assemble, then prime. Plastic takes primer readily and is very forgiving for beginners.
Resin prints may carry small nubs where supports were removed, so a quick tidy with a hobby knife or fine sanding stick is worthwhile. Always sand resin wet or wear a dust mask – you don’t want fine dust in your lungs. After that, a gentle wash and thin coats of primer give you a perfect surface. We cover every step in our guide on how to prep resin miniatures for painting.
Once primed, both materials paint the same way. The difference is that resin’s sharper edges catch drybrushing and highlights beautifully, rewarding you for every careful layer.
This is where 3D printed resin has quietly changed the hobby. Because sculptors don’t need to fund a steel mould, they can release niche monsters, unusual ancestries and enormous centrepieces that a mass-market plastic range might never touch. Creators such as Artisan Guild, Hardwitch, Pepunki Creatures and Rescale Miniatures publish new sculpts constantly, and print-on-demand means a shop can offer hundreds of designs without warehouses full of stock.
That variety matters most when you need something specific: the exact race-and-class combo for your DnD character, a proxy model for a points-based wargame, or a show-stopping boss. Browse our TTRPG and wargaming miniatures to see how broad the range has become – and if you play rules-agnostic systems, our post on why you should try One Page Rules explains how freely you can mix models from any creator.
For large statement models, resin has a clear edge. A sprawling dragon sculpted for display would need dozens of plastic parts and a huge mould, whereas a printer can produce it with the sculptor’s full detail intact. Pieces such as the Bahamut platinum dragon display mini or the brooding Elder Black Dragon on a 100mm base show what that means in practice: every scale and horn is there waiting for your brush. You’ll find more in our display models collection.
There’s no single winner – it depends on how you play and paint:
Whichever side of the forge you stand on, the magic happens when the paint goes on. If resin’s detail is calling to you, take a wander through our resin miniatures and find your next hero, villain or beast.
Generally, yes. Cured resin is harder and less flexible than polystyrene, so very thin parts can snap if dropped. Bulky models are perfectly sturdy, and careful storage and handling by the base prevents most breakages.
No. Plastic cement only works by melting polystyrene, so it won’t bond resin. Use superglue for most joins, and epoxy or pinning for heavy parts.
Absolutely. Once primed and painted, the two sit side by side happily. Just check scale (32mm heroic vs 28mm, for example) and, for tournaments, whether the event allows third-party models.
