On October 15, 2024, Panda3dp.com reported that Beijing 3D Printing Technology, Inc.'s（三帝科技）Xinxin Foundry has successfully delivered a monolithic, oversized aluminum alloy casting for users in the energy sector, utilizing 3DP sand casting technology. This casting, with a diameter of 2.5 meters and a weight of one ton, highlights a significant achievement, as traditional casting methods typically require approximately 60 days for completion, while Xinxin Foundry accomplished this in just 40 days.

In the manufacturing industry, the production of large castings has long posed a challenge. Traditional casting methods involve considerable technical difficulty and a cumbersome process, often causing significant issues for manufacturers. Addressing this challenge, 3DPTEK has developed a 4-meter ultra-large 3DP sand printer, offering a new solution for the industry. This device transcends traditional size limitations by employing a sandbox-free flexible area forming technology that supports localized printing, allowing for the creation of sand molds up to 4 meters in size. This innovation facilitates the integrated casting of large, complex structures, greatly enhancing production efficiency and casting quality. Notably, this equipment is highly cost-effective, priced at only the cost of a 2-meter device, thus economically enabling the manufacture of oversized sand molds (with 7-meter devices currently available for pre-order). Additionally, the company offers 1.6-meter and 1.8-meter 3DP sand printing solutions to cater to varying mold size requirements, along with an open-source material process that can be tailored to user needs. Complementary high-performance resin binders, curing agents, and cleaning solutions ensure the quality and stability of the formed products.

There is a broad demand for the manufacture of large castings across sectors such as aerospace, marine, automotive (new energy), and power generation (electrical), each with stringent requirements for product performance and manufacturing timelines. 3DPTEK's 3D casting process has provided customized solutions for numerous clients, crafting components for power devices with thin walls, curved surfaces, and large flat complex structures—tasks that traditional methods struggle to achieve. In the energy sector, they have delivered airtight enclosures with exceptionally high gas-tightness requirements, while in the new energy automotive field, they efficiently produced complex subframe castings with intricate curved structures and motor housings featuring complex spiral water channels.
