Fundamental Study on Applicability of Powder-Based 3D Printer for Physical Modeling in Rock Mechanics

摘要: Applications of 3D printing technology become more widespread in many research fields because its rapid development and valuable capabilities. In rock mechanics mining engineering, this has the potential to a useful tool that might help implement number studies previously considered impractical. Most commercial printers cannot print prototypes with mechanical properties match precisely those natural samples. Therefore, some additional enhancements are required for be effectively utilized applications. study, we printed studied specimens using powder-based ZPrinter® 450 ZP® 150 powder Zb® 63 binder used as raw materials. The by printer exhibited relatively low strength ductile behavior, implying it needs further improvements. Hence, focused on several ways determine best combination options post-processing including effects direction, layer thickness, saturation level, heating process uniaxial compressive (UCS) stress–strain behavior suggested procedures have demonstrated their effectiveness obtaining samples behave similarly rocks UCS. Although our optimization methods were particularly successful, improvements expand application area mechanics.
