In the field of high-end equipment manufacturing, the precision casting of key components has been a bottleneck that restricts the improvement of product performance. Whether it is the complex flow channel of ship pumps and valves, the high temperature resistant structure of aerospace power components, or the precision cavity of industrial machinery, the traditional casting process is faced with common challenges such as long mold development cycle, high cost, and difficulties in molding complex structures. Beijing SANDI Technology Co., Ltd (referred to as "SANDI Technology") unique 3DP + SLS composite sand casting technology, is a series of industry challenges for this breakthrough solution. The process creatively combines the advantages of two 3D printing technologies: the 3DP process for making high-precision outer molds, and the SLS process for molding complex inner cavities or fine piping cores. This combination of technologies not only realizes the structural complexity that is hard to reach by traditional processes, but also improves the strength of the sand core to 4-6MPa, which is much higher than the 1.5-2.5MPa level of traditional processes. In practical applications, this process has been successfully used in the high-precision manufacturing of complex structural parts for ship pumps and valves, aerospace power components, etc. Recently, Xinxin Casting, a subsidiary of SANDI Technology, successfully delivered a batch of highly difficult cast steel pump bodies for an industrial machinery customer. The structure of this batch of pump body is extremely complex, including several narrow inner cavities of only 2-3 millimeters in width, and need to withstand a casting temperature of up to 1750°C. The traditional casting method requires a production cycle of nearly 60 days. The traditional casting method requires nearly 60 days of production cycle, while the use of 3DP + SLS composite process, Xinxin casting only 20 days to complete the delivery of 10 products, in order to ensure the quality of the same time, the efficiency of the traditional process has increased by 3 times.

Previously, the technical reliability of the composite process has been verified in the aerospace field. The aircraft engine parts manufactured by SANDI Technology using this process have been successfully selected as a typical application list of additive manufacturing by the Ministry of Industry and Information Technology. While solving the complex oil circuit sand core printing problems, the process effectively overcomes the deformation of the traditional sand mold in the temperature return process, providing a new technical path for high-precision casting.

Supporting this innovative process is a system of 3D printing equipment independently developed by SANDI Technology. Among them.�Ӳ��:3DP Sand PrinterThe series is equipped with 400dpi ultra-fine printhead and precision motion control system, which can realize the highest printing accuracy of ±0.3mm. Through piezoelectric inkjet technology + high-resolution inkjet system + special binder, it realizes high-speed, precise and integrated molding of complex structural parts.

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.

Figure: SANTI Technology serves asTianjin Mechanical Engineering Society Casting Branch (Tianjin Foundry Society) 10th Council Executive Director Unit

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.
