Guidelines for Obtaining a GB6675 Test Report for Children's 3D Printers
I. Preliminary Assessment: Is your 3D printer subject to GB6675?
Applicable Conditions: The product is clearly targeted at children under 14 years old and possesses toy attributes in its packaging, advertising, or functional design (e.g., building blocks, colorful packaging, child-friendly interface, etc.).
Key Note: If the product is positioned as "educational equipment" or "maker tools" but is aimed at children, it may still be classified as a toy by regulators and subject to GB6675. The determination is based on the product classification of the State Administration for Market Regulation and the CCC mandatory certification catalog.
II. GB6675 Standard System (Series of Standards to be Tested)
| Standard Number | Test Content | Key Items
| GB6675.1 | Basic Specifications | Labeling Instructions, Age Grouping, General Safety Requirements
| GB6675.2 | Mechanical and Physical Properties | Small Parts, Sharp Edges and Angles, Extrusion Shearing, Drop Test, Noise, etc.
| GB6675.3 | Flammability | Material Burning Rate Test
| GB6675.4 | Migration of Specific Elements | 8 Major Heavy Metals (Lead, Cadmium, Chromium, Arsenic, Mercury, Selenium, Antimony, Barium)
3D printers also need to combine:
GB 4943.1 (Electrical Safety)
GB/T 26572 (Restriction of Hazardous Substances, RoHS Category)
EMC Electromagnetic Compatibility (if applicable)
III. Application Process
Step 1: Selecting a Testing Institution
Select an institution with CMA accreditation and CNAS accreditation Third-party laboratories (DEZEW Testing CNAS Registration No.: L8083) will be given priority consideration for:
Institutions with 3C certification qualifications
Step 2: Sample Submission and Technical Documentation Preparation
Sample Requirements:
2-3 complete machine samples (including packaging, instruction manual, and accessories)
Samples of key components/materials (e.g., plastic casing, printing consumables)
Technical Documents:
Product instruction manual (Chinese, including age warning)
Circuit schematic diagram, BOM list
List of key materials (plastics, coatings, wire composition)
Product photos and packaging samples
Step 3: Laboratory Testing
Testing cycle is typically 5-7 working days. Major additional tests include:
Mechanical and Physical: Protection of moving parts, high-temperature nozzle/heated bed warning, casing strength
Electrical Safety: Low voltage, temperature rise, insulation (in accordance with GB 4943.1)
Chemical Safety: Element migration of consumables (PLA/ABS) and small component coatings
Step 4: Report Issuance and Rectification
Pass: Report issued directly CMA Test Report (generally valid for 5 years, but subject to annual random inspections)
Non-compliant: The laboratory provides rectification suggestions; the company optimizes the design and resubmits for testing.
IV. Cost Reference
| Item | Cost Range (RMB)
| GB6675 Full Item Test | 800 ~ 2000 RMB
Actual costs depend on product complexity and the number of test items.
V. Key Considerations
1. Consumables (printing materials) must be included in the evaluation: PLA/ABS filaments are "accessible materials" and require elemental migration testing. It is recommended to use consumable suppliers that have passed food-grade or toy-grade certification.
2. High-temperature warning labels are essential: Printhead temperatures can reach 200~260℃, which is a hazardous source. Prominent warnings must be added to the product itself and the instruction manual.
3. Additional functions such as CNC/laser engraving require additional evaluation: If the equipment includes modules such as laser engraving, it may trigger additional safety requirements.
4. It is not recommended to "borrow" reports for adult products: The standards for adult 3D printers differ significantly from those for children's toys, and using the same report for both presents compliance risks.
5. E-commerce platforms are tightening their inspections: Tmall, JD.com, and Pinduoduo are increasingly rigorous in their qualification reviews of children's 3D printers. It is recommended to prepare CCC voluntary certification simultaneously after obtaining the report to enhance market trust.
