PLA vs PETG: Which 3D Printing Material is Best for Toys?

At RS3D, we use two main materials for our 3D printed toys: PLA (Polylactic Acid) and PETG (Polyethylene Terephthalate Glycol-Modified). Both have unique benefits, but which is better for your toy?

🌱 What Is PLA?

PLA is a plant-based plastic made from renewable resources like corn starch or sugarcane.

✅ Benefits of PLA for Toys:

• Eco-Friendly: Made from renewable resources

• Great Color Selection: Vibrant and wide-ranging

• Affordable: Cost-effective for customers

• Low Odor During Printing: Safer for home printing environments

• Stiff and Lightweight: Ideal for display miniatures and light-use toys

❌ Limitations of PLA:

• Lower heat resistance (can warp if left in hot cars)

• Slightly more brittle than PETG

🛡️ What Is PETG?

PETG is a durable, impact-resistant plastic commonly used for functional prints.

✅ Benefits of PETG for Toys:

• Stronger and More Flexible: Ideal for toys that get bent or squeezed

• Higher Heat Resistance: Less likely to warp in warmer environments

• Shiny Surface Finish: Gives toys a polished look

• Better Impact Resistance: Great for kids who play rough

❌ Limitations of PETG:

• Slightly more expensive

• Limited color choices compared to PLA

• Can be more stringy during printing (we take care to minimize this)

✅ Which Material Do We Recommend?

For display pieces, miniatures, and light fidgets, we usually use PLA.

For flex toys, fidgets that get bent a lot, or toys used outdoors, we often use PETG.

If you have a special material request, just leave a note at checkout—we’re happy to accommodate when possible.
