コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies specifically to fused deposition modeling (FDM) machines, commonly known as 3D printers utilizing material extrusion technology. It covers the safety and safeguarding technical requirements for the design, manufacture, and operation of these machine tools. It is not applicable to other types of additive manufacturing or rapid prototyping equipment that do not use the fused deposition modeling process.

技術要求

The standard outlines comprehensive safety measures to mitigate mechanical, electrical, and thermal hazards. For mechanical safety, it mandates that moving parts have reliable dual electrical and mechanical limit switches, and requires interlocked protective doors for the machining area to prevent operation when opened. Manufacturers must ensure the nozzle clamping device is secure to prevent ejection hazards during high-speed movement. Regarding thermal and electrical safety, the standard specifies that the nozzle heating system must feature reliable automatic temperature control and thermal insulation measures to prevent burns. The forming chamber door must be interlocked with the nozzle heating system to prevent opening during active heating or processing. Electrical equipment within the forming chamber must meet extra heat-resistance requirements, adhering to GB 5226.1. Additionally, the standard sets requirements for noise emission limits (not exceeding 60dB(A)) and mandates proper ventilation interlocks. It also requires comprehensive user information, including detailed warning labels, safety symbols, and a durable instruction manual detailing transportation, installation, operation, and maintenance safety protocols.

試験方法

Compliance is verified through a combination of visual inspections, manual checks, and specific functional tests. Key testing procedures include verifying the reliability of interlock devices (repeated 3 times), checking the response of heating system temperature controls, and conducting electrical safety tests. Electrical testing involves protective grounding continuity, insulation resistance, and dielectric strength tests according to GB 5226.1. Noise measurement is conducted following the methods specified in GB/T 16769, and hazardous gas emissions are evaluated per GB/T 18569.

よくある質問
