High-throughput computing, high-throughput experiment and database technology are the three key technologies
of Material Genetic Engineering, which aim to accelerate the design and development of new materials efficiently.
Motivated by a new generation of intelligent manufacturing in China, digital twin technology has become a key technology
for data-driven Integrated Computational Materials Engineering (ICME). For precision casting technology, a method and
system integrating casting performance testing of metal materials and high-throughput preparation of standard samples were
established, including casting system optimization design, casting performance testing system and high-throughput
preparation array system of standard samples. By integrating 3D printing technology, the digital twin of system design and
preparation was realized. The results show that the wax mold prepared by the high-throughput sample preparation array
combination system has high precision, flexible and convenient combination of functional modules and units, which can
save the traditional mold tools, reduce the cost, reduce the processing amount and raw material consumption of mechanical
properties samples, and shorten the preparation time. The integrated system can also be used for the samples preparation
process of sand casting, metal mold casting and precision casting.
