# 3D 打印安全

3D 打印为创建功能性、定制化部件打开了大门，但也带来了重要的安全考量。材料选择只是其中一部分。打印过程本身，包括温度、硬件和设计，都会直接影响最终制成的物体是否适合其预期用途并且安全。本节对在使用 3D 打印部件时需要牢记的关键安全主题提供了高层概览。

### 食品安全 <a href="#food-safety" id="food-safety"></a>

某些原材料在其基础形态下可能符合食品接触标准，在欧盟等地区也存在某些认证。然而，在美国，FDA 不会对原始丝材进行认证。相反，认证适用于最终制造出来的物体。对于 3D 打印而言，层纹、表面孔隙率、打印设置，甚至喷嘴材料等因素都可能带来污染风险。因此，一种在原始状态下可能被认为适合食品接触的丝材，打印后制成的物体却可能并不适合食品接触。

### 儿童和玩具安全 <a href="#child-and-toy-safety" id="child-and-toy-safety"></a>

诸如 EN 71-3 和 CPSIA 风格文件等材料合规标准，可以针对特定产品实现，而且相关工作仍在推进，以扩展可认证的材料选项。尽管如此，安全并不仅由材料本身决定。打印质量起着重要作用。层间粘接不良、锋利边缘、可拆卸的小部件或脆性打印件都可能造成危险。即使某种材料符合玩具安全标准，具体成品仍可能因打印和后处理方式不同而不安全。

### 皮肤接触安全 <a href="#skin-contact-safety" id="skin-contact-safety"></a>

某些材料可以使用 ISO 10993 等标准评估生物相容性，该标准包括细胞毒性、刺激性、致敏性和全身毒性测试。PolyFlex TPU90 就是一种已通过多项 ISO 10993 测试的材料，另外还有更多材料正在接受评估。

随后，REACH 和 RoHS 声明也很有用，因为它们表明是否有意避免使用受限物质和某些有害材料，或将其含量控制在限值以下。

即使使用经过测试的材料，打印条件、后处理以及清洁程度也会影响打印部件是否适合长时间与皮肤接触。

### 室内空气质量 <a href="#indoor-air-quality" id="indoor-air-quality"></a>

3D 打印在打印过程中可能会释放超细颗粒和挥发性有机化合物。某些材料在加热时也可能产生明显气味。这些排放会因材料和打印设置而异。无论材料类型如何，都建议在通风良好的区域操作所有 3D 打印机，包括常用的 PLA 等丝材。关于排放和空气质量影响的研究仍在持续。

### 其他认证与声明 <a href="#other-certifications-and-declarations" id="other-certifications-and-declarations"></a>

除了针对具体应用的安全考量外，材料层面的合规性和化学安全声明也同样重要。这些可能包括关于受限物质、环境法规和化学成分的声明。示例包括对 REACH、RoHS、TSCA 等法规的合规性，以及涵盖 PFAS、BPA、PAHs 和其他物质类别的声明。这些文件有助于提高材料成分的透明度，但它们不能取代对最终打印物体安全性的评估。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://wiki.polymaker.com/polymaker-wiki/polymaker-wiki-zh/polymaker-chan-pin/geng-duo-guan-yu-wo-men-chan-pin-de-xin-xi/3d-da-yin-an-quan.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
