Evaluating a 3D printing service provider's technical capabilities hinges on examining their process coverage, equipment sophistication, material compatibility, and whether they provide authoritative performance test reports. This ensures they can accurately match your project needs and consistently deliver high-quality results.
Process Coverage: Assessing Comprehensive Service Capabilities A technically strong service provider should not rely on a single printing technology but should offer multiple processes to address different application scenarios:
FDM (Fused Deposition Modeling): Suitable for large-size structural parts or functional prototypes; low cost but relatively rough surface; commonly used for tooling fixtures and educational models.
SLA/DLP (Solar Lamination/Deposition Processing): Layer thickness up to 0.05mm; high detail reproduction; suitable for high-precision appearance verification parts, medical models, and cultural and creative figurines.
SLS (Selective Laser Sintering): No support structure required; can directly print complex geometric nylon parts; suitable for functional test parts and lightweight structures.
Metal SLM/SLS (Laser Melting/Sintering): Used to manufacture high-performance metal parts such as stainless steel and titanium alloys, widely used in aerospace and medical device fields.
MJF (Multi-Jet Melting): HP technology, suitable for small to medium batch production of nylon parts, producing uniform surface and stable mechanical properties.
Recommendation: Prioritize service providers that master more than 3 mainstream processes, such as Beijing Haopeng Technology, which covers SLA, SLS, SLM, and MJF processes and possesses full-chain solution capabilities.
