Rationale

This test method is essential for industries involved in the development of extrusion-based 3D printers as well as those formulating cementitious materials for additive manufacturing across various applications. Currently, the lack of standardized methods to define printability limits the scalability and reliability of 3D printing in construction and related sectors. Most existing approaches rely on qualitative assessments, with limited reproducibility or correlation to measurable rheological parameters. This standard provides a systematic, quantitative framework for identifying the printability zone based on the interaction between rheological properties (yield stress and viscosity) and printability factors (extrudability, shape retention, and layer deposition). The standard supports greater process control, improved material performance, and broader adoption of extrusion-based additive manufacturing technologies by enabling consistent evaluation and optimization of printable materials.
