How to Choose a 3D Printing Service in China

1. Define the required process. SLA and similar resin processes can suit detailed appearance models, while SLS or MJF may be preferable for certain functional nylon parts. Metal printing, FDM, and other processes have different design and finishing requirements.
2. Match the material to the application. Confirm strength, flexibility, heat resistance, chemical resistance, transparency, biocompatibility, and long-term environmental exposure rather than selecting material by name alone.
3. Review tolerances and inspection. Ask how critical dimensions are measured, which inspection documents are supplied, and whether first-article approval is available.
4. Clarify finishing. Confirm support removal, sanding, polishing, painting, dyeing, coating, machining, assembly, and the expected appearance of difficult surfaces.
5. Check quantity and production stage. A provider optimized for one prototype may not be the best option for repeat batches, bridge production, or tens of thousands of parts.
6. Compare total landed cost. Include tooling, post-processing, packaging, freight, duties, taxes, and any design or inspection fees.
7. Protect design information. Confirm file handling, intellectual-property ownership, confidentiality, and the permitted use of uploaded CAD data.
8. Evaluate communication. For complex parts, a supplier that reviews drawings, tolerances, finishes, and delivery expectations can reduce avoidable production errors.
9. Verify the business model. Exhibitions and professional organizations can be valuable research resources, but they are not necessarily manufacturers. Confirm who will actually produce and inspect the parts.
