Stereolithography (SLA) is the original 3D printing technology, using a UV laser to cure liquid photopolymer resin into solid plastic layer by layer. SLA 3D printing is renowned for its smooth surface finish and near-invisible layer lines, making it the industry standard for high-detail resin printing.
From tabletop gaming miniatures to dental models, SLA delivers the precision that filament-based printing cannot match. If you need professional-grade miniatures or presentation-ready prototypes, SLA is your ideal solution.
Best Applications for SLA Printing
- Highly detailed miniatures – Captures tiny accessories and sharp textures
- Lifelike figurines – Realistic facial features without visible layer lines
- Jewelry prototypes – Intricate settings and fine engravings
- Master patterns for molding – High-resolution masters for silicone molds
- Functional prototypes – Injection-molded part simulation
How SLA 3D Printing Works
The resin 3D printing process follows these steps:
- Build platform lowers into liquid resin tank
- UV laser traces the cross-section, hardening the resin
- Platform lifts to peel the cured layer
- Fresh resin flows beneath for the next layer
- After printing, supports are removed and part is UV-cured
SLA Materials
| Material | Best For | Properties |
|---|---|---|
| TGM-7 High Detail Plastic | Miniatures, figurines, collectibles | Hard, smooth surface with balanced toughness |
SLA Design Guidelines
| Design Feature | Requirement |
|---|---|
| Maximum bounding box | ( 218 \times 122 \times 260 , \text{mm} ) |
| Supported walls | ( 0.6 , \text{mm} ) |
| Unsupported walls | ( 0.8 , \text{mm} ) |
| Embossed/engraved details | ( 0.1 , \text{mm} ) |
| Minimum clearance | ( 0.5 , \text{mm} ) |
| Accuracy | ( \pm 0.2% , (\text{min} \pm 0.2 , \text{mm}) ) |
| Critical SLA design tips: |
- Avoid fully enclosed voids (trapped resin causes cracking)
- Minimize overhangs greater than 45°
- Ensure openings are large enough for support removal
