On April 19, 2025, "Advanced Materials and Foundry New Technology Forum and the 10th Tianjin Foundry Annual Conference", organized by Tianjin Mechanical Engineering Society Foundry Branch and National Key Laboratory of Advanced Roll Materials and Composite Forming, was held at Beichen Campus of Hebei University of Technology. (hereinafter referred to as "SANDI") participated in the meeting as the support unit of this forum.

In the morning forum on the 19th, Dr. Zong Guisheng, Chairman of SANDI Technology, shared the oversized sand 3D printing solutions. For the aerospace, shipbuilding and heavy industry and other fields have long been plagued by ultra-large castings manufacturing problems, Dr. Zong Guisheng in-depth analysis of the bottlenecks of the traditional process in terms of efficiency, cost and quality, and focused on the revolutionary technological breakthroughs of SANDI Technology's self-developed 4-meter ultra-large-size 3DP sand printer 3DPTEK-J4000.

The equipment adopts sandbox-free flexible area molding technology, which breaks through the size limitation of traditional casting, and can support up to 4-meter sand manufacturing. Its core technical advantages are reflected in the following: 1. integrated molding of complex structures: through high-precision nozzles and intelligent algorithms, it realizes one-time molding of large-size, thin-walled, multi-dimensional curved surfaces and complex cavities (such as helical cooling water channels), breaking through the limitations of the traditional process on the design of the space; 2. high efficiency and low cost: compared with the traditional split casting, the production cycle is shortened by more than 50%, for example, a 1.25-ton aluminum alloy casting is compressed from 60 days to 15 days to complete the delivery of the traditional process; 3. economic optimization: the price of the equipment is only comparable to the equipment of the 2.5-meter class, and the open source material process supports the adjustment of the binder and the sand formula on demand, to further reduce the overall cost.
