The rapid rise of 3D printing, both in industrial and home settings, presents emerging health and environmental risks. While 3D printing enhances sustainability by reducing waste and optimizing resource use, its impact on human health remains poorly understood. The use of metals and polymers linked to health risks, coupled with the release of inhalable particles and volatile organic compounds, raises concerns about respiratory and systemic effects. The absence of clear guidelines creates high public demand for information and limits safe implementation, particularly in schools and homes where millions of 3D printers are expected by 2030. Additionally, improper disposal of 3D printing polymer materials may exacerbate plastic pollution. This article proposes the perspective of a structured risk assessment framework set on particle emissions from industrial 3D printing. It will offer a practical tool to bridge current knowledge gaps and to inform safe practice and policy development, because immediate action is necessary to balance innovation with safety.
3D打印在工业和家庭环境中的迅速兴起带来了新出现的健康和环境风险。虽然3D打印通过减少浪费和优化资源利用提高了可持续性，但其对人类健康的影响仍知之甚少。与健康风险相关的金属和聚合物的使用，以及可吸入颗粒和挥发性有机化合物的释放，引发了对呼吸和全身影响的担忧。缺乏明确的指导方针导致公众对信息的需求很高，并限制了安全实施，特别是在到2030年预计将有数百万台3D打印机的学校和家庭中。此外，3D打印聚合物材料的不当处置可能会加剧塑料污染。本文提出了一个基于工业3D打印颗粒排放的结构化风险评估框架的观点。它将提供一个实用工具，以弥合当前的知识差距，并为安全实践和政策制定提供信息，因为必须立即采取行动，在创新与安全之间取得平衡。
