# Child and Toy Safety
Toy safety is more than choosing a material that looks child-friendly. A printed part may pass a chemical migration test, but the finished toy still has to be safe as a physical object, which is where 3D printing can create extra risks. For products meant for children, the material, design, print quality, and finishing all matter at the same time.
### What EN 71-3 Covers
EN 71-3 focuses on chemical migration, especially the release of certain elements such as lead and cadmium from toy materials when they are mouthed, licked, or swallowed. That makes it useful for evaluating whether a material can limit harmful leaching, but it does not tell you whether the finished toy is mechanically safe. In practice, EN 71-3 is only one part of toy safety, not the whole picture.

### Why Finished Toys Need More
A toy can still fail even when the base material meets EN 71-3. EN 71-1 covers mechanical and physical safety, including sharp edges, points, and small parts that can create choking hazards, while EN 71-2 covers flammability. The same idea applies in the U.S., where ASTM F963 and CPSIA-based requirements look beyond chemistry and include issues like small parts, durability, and foreseeable abuse. That means a print that is chemically compliant can still be unsafe if it snaps, splinters, or leaves loose pieces behind.
### 3D Printing Risks
FDM prints can be risky for children because layer adhesion, brittle walls, and rough finishing can create breakage or sharp fragments. If a child bites, drops, or repeatedly handles the item, weak layer bonding and thin features can become a real safety issue. Small accessories, removable eyes, clips, and decorative parts are especially important because they can become choking hazards if they detach.
### Cleanability and Mouth Contact
Young children often mouth toys, so cleanability matters as much as strength. Layer lines, seams, and support scars can trap dirt and saliva, which makes printed parts harder to sanitize thoroughly. Pigments and additives also deserve attention because chemical compliance depends on the whole formulation, not just the base polymer.
### Best Use Cases
The safest uses are usually limited to low-risk items such as teaching aids, display pieces, and decorative goods that are not intended for unsupervised play. For Etsy or MakerWorld sellers, it is smart to treat any child-facing print as a product, not just a model, because the final object has to survive use, abuse, cleaning, and accidental mouth contact. If the item is meant to be a real toy, it should be evaluated as a complete finished product, not as a filament alone.
### Practical Rule
The short version is simple: EN 71-3 material testing is helpful, but it does not equal complete toy compliance. A safe toy needs chemical safety, mechanical safety, flammability consideration, and a design that avoids choking, sharp edges, and weak parts. For 3D printing, the printed object is always the real safety test.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://wiki.polymaker.com/polymaker-products/more-about-our-products/safety-in-3d-printing/child-and-toy-safety.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
