- Introduction
1. Background and significance of the standard
With the rapid development of additive manufacturing technology, the role of 3D process models in the production process is becoming increasingly important. In order to ensure the quality and processing efficiency of formed parts, the GB/T 43481-2023 standard came into being, aiming to standardize the data quality requirements of 3D process models.
2. Comparison of standard frameworks
Dimensions GB/T 43481—2023 Reference standard GB/T 39331—2020 International standard ISO/ASTM standard Data processing flow New requirements for quality inspection of 3D process models General data processing specifications No clear specifications Data quality requirements Refined triangle mesh consistency requirements Basic mesh requirements Unified mesh standards Quality inspection method Introduction of topological information inspection Simple geometry verification Not involved 3. Technology evolution analysis
Additive manufacturing technology has gradually moved from the early experimental stage to industrial application, and the data quality requirements of 3D process models have also evolved accordingly. Early standards focused on basic geometric representation, while GB/T 43481-2023 introduced stricter topological information and normal consistency requirements, reflecting the industry's higher demand for data processing accuracy.
4. Implementation suggestions
- Data preparation stage:Ensure that the 3D process model follows the standard requirements when it is generated, especially the closure and normal consistency of the triangular mesh.
- Quality inspection stage:Use professional tools for topological information verification and geometric error analysis.
- Slicing stage: Models that do not meet quality requirements should be repaired in a timely manner to avoid affecting the forming effect.
