Ever try to print miniatures on your FDM printer and end up with something that looks like a melted gummy bear holding a sword? Yeah, me too. But here’s the thing — you can get amazing miniatures out of an FDM printer. You just have to treat it like a delicate little art project and give it the care it deserves.
In this guide, we’ll cover everything you need to know to make your FDM miniatures look sharp, detailed, and ready for paint — without switching to resin.
Start With the Right Nozzle Size
That standard 0.4 mm nozzle that comes with most printers? It’s basically like trying to paint a miniature with a broom. If you want clean edges and sharp details, swap it out for a 0.2 mm nozzle.
The smaller nozzle lets you capture fine textures like armor plates and crisp sword edges — just keep in mind your print times will go up. A print that normally takes two hours could take four or more. So, grab yourself a coffee (or two). It’s worth it.
Dial In Your Layer Height
Layer height is where the magic happens. For miniatures, you’ll want to stick between 0.08 mm and 0.12 mm. This is the sweet spot for smooth surfaces that don’t look like your characters have scales for skin.
If you’re not sure where to start, remember this simple rule:
Your layer height should be 25–50% of your nozzle size.
Go smaller, and you’ll be printing into the next Ice Age.
Slow It Down
FDM printing miniatures isn’t a race. Modern printers are fast, but for fine detail, slower is better. If you print too quickly, your wizard’s face might end up looking like he teleported into a wall.
Take your time — your printer (and your paintbrush) will thank you later.
Choose the Right Model
Not all models are made for FDM printing. A lot of what you find online is designed for resin printers — and trust me, some of those models will make your FDM printer cry.
If you’re browsing sites like Thingiverse, Printables, or MakerWorld, look for models labeled “optimized for FDM.”
Here’s a tip:
-
Chunky details (thick armor, large weapons, bold features) = great for FDM.
-
Thin swords, wispy hair, or floating daggers = heartbreak waiting to happen.
If you’re printing 32 mm miniatures, aim for models with bulkier details to avoid fragile prints that snap or warp.
Use High-Quality Filament
When you’re printing small, filament quality matters more than ever. Stick with high-quality PLA or PLA+. It holds sharp edges, resists warping, and is easier to paint afterward.
Avoid fancy filaments like metallic, wood, or carbon-fiber blends — those can clog your 0.2 mm nozzle faster than a milkshake through a coffee straw.
Master Cooling and Retraction
Cooling and retraction settings make or break your miniatures. Keep your cooling fan at 100% during printing, and dial in your retraction distance to reduce stringing or blobs.
If your print starts looking like it got webbed by Spider-Man, it’s time to tweak those settings until you get clean lines.
Smarter Supports = Cleaner Miniatures
Supports are like that one friend who always means well but goes overboard. Too much, and you’ll spend more time sanding than painting.
If your slicer has tree supports, use them — they’re easy to remove and minimize surface scars.
If your slicer offers support interfaces, turn them on. They make supports peel off like string cheese instead of tearing into your print.
Some model creators (like Loot Studios) even include pre-supported FDM versions. Those can save you a lot of time and frustration.
Keep It Cool — Literally
Here’s a sneaky pro tip: print two or three miniatures at the same time.
When you print just one, the nozzle keeps dumping heat into the same area, which can cause droopy swords and sagging faces. Printing multiple models gives each one a moment to cool between layers, leading to sharper results.
Patience Is the Secret Ingredient
FDM miniature printing is more about patience than anything else. Take your time, tune your settings, and pick the right model — and you’ll be surprised how close your results come to resin printing.
Sure, it might not match resin’s perfect detail, but you’ll avoid sticky gloves, smelly cleanup, and fragile prints that shatter when you sneeze.
So go ahead — print your hero, your dragon, or your goblin army.
And remember:
The only failed print is the one you didn’t start.
