WiseBeginner (智小白), a Nanjing Gongfudou brand, lists PLA as the filament for its children’s 3D printers. SunDots supplies filament to WiseBeginner. For a replacement spool, check the exact Explorer model and its feed system. For a school purchase, ask for the material grade, colour and matching test report.
Start with the printer model and feed system
The Explorer 7 can read filament information and match print parameters automatically, according to WiseBeginner. Before buying a refill, check the spool dimensions, filament diameter and whether your feeder can identify the spool. Ask which material profile to select if identification is unavailable.
Match the report to the actual sample
For a school purchase, match the grade and colour on the spool to the sample on the report. On 1 July 2026, SGS reported a pass for migration of specified elements under EN 71-3:2019+A2:2024, Category III, for three PLA samples submitted by Sungallon. Each report applies to the sample named on it.
- PLA Green — CANEC26017081901
- PLA Matte Fruit Green — CANEC26017081902
- PLA + Silk Metallic Purple — CANEC26017081903
Plan a small, supervised evaluation
Follow the printer manufacturer’s supervision and ventilation instructions. Inspect the finished object for sharp edges, small detachable parts and other hazards specific to its intended use.
Before a larger order, request the exact grade and colour. Send SunDots the printer model, feed system and trial quantity so the team can check the spool and its documents.
