Pre-Supported vs Unsupported STL Files – Which One Should You Use for 3D Printed Miniatures?
If you’ve downloaded a 3D printable miniature and noticed both pre-supported and unsupported STL files, you might be wondering which version is right for your resin printer. Understanding the difference can dramatically improve your print quality, reduce failures, and save resin.
In this guide, we’ll break down the pros, cons, and ideal use cases for each type of STL file — especially for fantasy tabletop miniatures and high-detail 40mm resin prints.
What Is a Pre-Supported STL File?
A pre-supported STL file is a 3D model that already includes professionally placed supports. These supports hold the miniature in position during resin printing and prevent deformation or print failures.
For tabletop RPG miniatures and detailed fantasy models, proper support placement is crucial. Thin elements like claws, weapons, ears, or hair strands require precise support density and positioning.
- Ready to print immediately
- Optimized for resin 3D printing
- Reduces risk of beginner mistakes
- Saves preparation time
What Is an Unsupported STL File?
An unsupported STL file contains only the raw 3D model geometry without any supports attached. This version gives you full control over orientation, scaling, and support generation inside your slicer software.
Unsupported files are ideal for experienced resin printing users who want to customize support density or scale the miniature beyond its original size.
- Full control over support placement
- Best for scaling miniatures larger
- Optimized for advanced users
- Compatible with custom resin settings
Pre-Supported vs Unsupported STL – Key Differences
| Feature | Pre-Supported STL | Unsupported STL |
|---|---|---|
| Beginner Friendly | Yes | No |
| Custom Scaling | Limited | Ideal |
| Time to Print | Faster Setup | Requires Preparation |
| Advanced Customization | Limited | Full Control |
When Should You Use Each Type?
Use Pre-Supported Files If:
- You are new to resin 3D printing
- You want reliable results immediately
- You are printing at original scale (e.g., 40mm)
Use Unsupported Files If:
- You plan to scale the miniature larger
- You prefer custom support density
- You use advanced resin settings

Frequently Asked Questions
Do pre-supported STL files work on every resin printer?
In most cases, yes. However, minor exposure adjustments may be required depending on your resin type and printer model.
Can I scale a pre-supported miniature?
Scaling is possible, but supports may not remain optimized. It is recommended to use the unsupported version for scaling.
Why do miniatures fail without proper supports?
Resin printing requires controlled layer adhesion. Unsupported islands or thin parts can detach mid-print, causing failures.
