When it comes to creating custom 3D figurines, choosing the right printing material (PLA and Resin) plays a vital role in the final product’s quality, durability, and aesthetic appeal. Whether you’re making 3D figures to print, designing a 3D pen figure, or crafting 3D personal action figures, selecting between PLA and resin can significantly impact the toy’s functionality and appearance.
In this guide, we’ll break down the key differences between PLA and resin, explore their pros and cons, and help you make the best choice for your next custom figurine project.
What Are PLA and Resin in 3D Printing?
PLA (Polylactic Acid)
PLA is one of the most popular and eco-friendly filaments used in FDM (Fused Deposition Modeling) 3D printing. It’s made from renewable plant-based materials like corn starch or sugarcane, making it biodegradable and non-toxic—perfect for custom figurines and toys.
PLA is widely used for producing 3D figures to print because of its ease of use and affordability.
Resin
Resin is commonly used in SLA (Stereolithography) and DLP (Digital Light Processing) 3D printing, offering highly detailed and smooth finishes. Resins are typically made from photopolymer liquids that harden under UV light, making them ideal for 3D personal action figures or artistic display figurines that require intricate details.
Comparing PLA vs. Resin for 3D Printed Figurines
Choosing between PLA and resin depends on your design goals, purpose, and budget. Let’s compare both materials across several factors:
1. Print Quality & Surface Finish
| Feature | PLA | Resin |
| Surface Finish | Textured, visible layers | Ultra-smooth, detailed |
| Level of Detail | Good for simple models | Excellent for fine details |
| Ideal Use | 3D figures to print and 3D pen figures | 3D personal action figures and miniatures |
✅ If you’re making 3D personal action figures with intricate facial features or small accessories, resin is the better option for superior detailing.
2. Durability & Strength
| Feature | PLA | Resin |
| Durability | Moderate, slightly brittle | Strong but brittle |
| Flexibility | Low | Low |
| Impact Resistance | Low | Higher for tough resins |
PLA is more durable for larger, static display models like 3D figures to print, while resin is best for high-detail display figurines that don’t require frequent handling.
3. Ease of Printing
| Feature | PLA | Resin |
| Printer Type | FDM | SLA/DLP |
| Setup Complexity | Easy | More complex |
| Post-Processing | Minimal | Requires cleaning and curing |
| Safety | Non-toxic | Can be toxic without proper handling |
PLA is beginner-friendly and ideal for creating 3D pen figures or simple collectible models. However, resin requires additional post-processing steps like washing and UV curing.
4. Eco-Friendliness
| Material | Biodegradable | Recyclable | Safety |
| PLA | ✅ Yes | ✅ Yes | ✅ Non-toxic |
| Resin | ❌ No | ❌ Limited | ⚠️ Can contain toxic chemicals |
If you’re producing eco-friendly toys like 3D personal action figures, PLA is the more sustainable choice.
When to Choose PLA for Custom Figurines
PLA is the best option if:
- You’re designing 3D figures to print for display purposes.
- You need a cost-effective material.
- You’re working on larger models with simpler shapes.
- You prefer a non-toxic, child-safe filament.
- You’re creating custom 3D pen figures with layered textures.
Best Figurine Types for PLA
✅ Collectible 3D figures to print
✅ Educational models
✅ Toy prototypes
✅ Large custom statues
When to Choose Resin for Custom Figurines
Resin is the better choice if:
- You need high-detail miniatures like 3D personal action figures.
- Your figurine has complex details like facial expressions or small parts.
- You’re making display-quality collectibles.
- You’re okay with spending more time on post-processing.
- You’re creating limited edition models or decorative pieces.
Best Figurine Types for Resin
✅ 3D personal action figures
✅ Board game miniatures
✅ Movie character collectibles
✅ Fantasy figurines
✅ High-end custom toys
Cost Comparison
| Feature | PLA | Resin |
| Material Cost | $20–$30 per kg | $40–$100 per liter |
| Printer Cost | $300–$700 | $300–$1,000 |
| Post-Processing Cost | Low | High |
Final Decision Guide
| Type of Figurine | Recommended Material |
| Display Models | PLA |
| Custom Action Figures | Resin |
| Pet Toys | PLA |
| Miniature Collectibles | Resin |
| Large Decorative Figures | PLA |
| High Detail Art Figures | Resin |
How to Choose the Right Supplier for 3D Printed Figurines
A trusted supplier can guide you in selecting the best material for your figurine designs. Here’s what to look for:
- Use of eco-friendly materials
- Compliance with US & EU safety regulations
- Custom printing options

- High-quality printing equipment
Conclusion
Choosing between PLA and resin for custom 3D printed figurines depends on your figurine’s purpose, detail requirements, and budget. If you’re creating 3D figures to print or 3D pen figures for display or educational purposes, PLA is the ideal choice for its cost-efficiency, safety, and eco-friendliness. However, for 3D personal action figures and detailed collectibles, resin offers unmatched precision and aesthetics.
