Ever wanted to hold Cloud’s Buster Sword, Master Chief’s helmet, or a Valorant knife? With 3D printing, you can!
Gamers and cosplayers are using 3D printers to recreate epic props and weapons from their favorite games, right at home.
This blog covers how to find files, print, assemble, and paint gaming weapons — safely and affordably.
🎯 What Are Game Props in 3D Printing?
Props include any in-game item recreated physically:
- Weapons (swords, guns, staffs)
- Armor (helmets, shields, gauntlets)
- In-game items (potions, runes, relics)
They’re used for:
- Cosplay
- Room décor
- Collectibles
- Display at gaming cafés or events

🛠️ Printing Large Weapons
Large props often require:

💡 Example: Buster Sword from Final Fantasy may print in 6–8 parts and assemble to a 3–4 ft model.
🧵 Materials & Settings
| Material | Use Case | Tip |
|---|---|---|
| PLA | Swords, light shields | Easy, cheap |
| PETG | Props with flexibility need | Stronger than PLA |
| ABS | Heat resistance (outdoor cosplay) | Needs enclosure |
| Foam Fill | For hollow parts | Reduces weight |
📏 Use 0.2mm layer height for strength
🪛 Add M3 inserts for screw-tight assembly
🎨 Painting & Finishing
Steps:
- Sand seams and support marks
- Prime (grey or white)
- Base coat + shading (acrylics or spray)
- Add metallic, weathering, or blood effects
- Clear coat to seal
🎯 Optional: Add LEDs for glowing swords, potions, etc.
⚠️ Legal Note:
Creating for personal use or cosplay = ✅ okay
Selling unlicensed replicas = ❌ risky (infringes IP)
To sell:
- Use original designs
