Master, a Warhammer hobbyist, or a fan of crafting unique display pieces, knowing how to 3D print miniatures can open a world of creative possibilities.
This step-by-step guide breaks down everything you need to know to get started with printing miniatures in high detail, the right way. From choosing a printer to post-processing your models, we’ll cover it all.
Step 1: Choose the Right 3D Printer for Miniatures
When it comes to printing miniatures, resin printers (SLA/LCD) are the gold standard due to their high resolution and smooth finish.
Recommended Resin Printers for Beginners:
- Anycubic Photon Mono M5s – 12K detail, user-friendly, auto-leveling
- Phrozen Sonic Mini 8K S – Industry-leading resolution (22 µm)
- Elegoo Mars 4 Ultra – Budget-friendly, 9K clarity, great for starters
FDM printers can also be used, but resin provides significantly sharper results.
Step 2: Get or Design a 3D Model
You’ll need a 3D model in STL or OBJ format. There are two ways to get miniatures:
Download From Trusted Platforms:
- MyMiniFactory
- Cults3D
- Thingiverse
- Loot Studios (premium packs)
Or Design Your Own:
- Use Blender, Nomad Sculpt, or ZBrush
- Try ChatGPT’s new 3D modeling feature to generate AI-based base meshes, which can be modified in your software of choice
Tip: Look for miniatures with pre-supported versions if you’re a beginner.
Step 3: Slice the Model for Printing
Before printing, the model needs to be converted into printable instructions.
Best Slicer Software:
- Lychee Slicer – Feature-rich and intuitive
- ChiTuBox – Popular for most resin printers
- PrusaSlicer – Excellent FDM support
Key Settings:
- Layer Height: 0.02mm–0.05mm for miniatures
- Supports: Use light supports for resin prints
- Orientation: Tilt models at 45° to reduce suction and improve detail
Step 4: Set Up and Start the Print
Resin Printing Checklist:
- Fill the resin vat with enough resin
- Make sure the build plate is leveled (auto or manual)
- Double-check your slicing settings
Start the print and let your machine work its magic! Most miniatures take 3–6 hours depending on size and resolution.
Step 5: Post-Processing the Miniature
Post-processing is essential for resin prints to finalize your miniature.
🧴 Cleaning:
- Use Isopropyl Alcohol (90%+) to wash off uncured resin
- Ultrasonic cleaners make this easier
🌞 Curing:
- Cure the miniature under a UV light or use a UV curing station
✂️ Support Removal:
- Use snips to gently remove supports after curing
Safety First: Always wear gloves and work in a ventilated area.
Step 6: Prime and Paint (Optional but Recommended)
Once your miniature is ready, you can prime and paint it for incredible results.
Best Practices:
- Use spray primer (gray or white) before painting
- Paint with acrylic paints and fine brushes
- Consider dry brushing, washes, and highlights for depth
Bonus: Use airbrushes for smoother blends on large models.
Bonus: Where to Sell or Share Your Miniatures
After printing and painting, you can showcase or sell your creations:
Best Platforms:
- Etsy – For painted miniatures or custom prints
- MyMiniFactory – Sell STL files
- Patreon – Offer monthly packs or exclusives
- Instagram / TikTok – Build a brand and drive sales
You can even use ChatGPT’s AI model design tool to expand your offerings and automate the creation process!

FAQs
1. What is the best resolution for printing miniatures?
0.02mm layer height and 8K–12K XY resolution is ideal for sharp details.
2. Can I use FDM printers for miniatures?
Yes, but expect less detail and visible layer lines. Resin is preferred.
3. Is ChatGPT useful in creating 3D miniatures?
Yes! ChatGPT’s new feature can generate base meshes and help you brainstorm creative models.
4. Do I need supports for miniature prints?
Yes. Supports ensure overhangs and fine details are printed successfully.
5. Is post-curing mandatory?
Yes. Without proper curing, resin models remain soft and may deform over time.
