3DPTEK's 4-Meter Sand Mould 3D Printing Machine Wins Innovation Award at Casting Expo, Enhancing Industry Quality and Efficiency Through 3D Casting.

During the "Frontier Casting Technologies" forum at the Annual Meeting of the China Foundry Association on July 3, Dr. Zong Guisheng, Chairman of Beijing 3D Printing Technology, Inc.(北京三帝科技股份有限公司) delivered a keynote report titled "High-Efficiency, Low-Cost Metal Additive Manufacturing Technology and Application Progress." Dr. Zong shared significant advancements in metal additive manufacturing that enhance manufacturing efficiency and reduce costs, as well as case studies on the industrialization and typical applications of 3D casting. He emphasized that over the past four decades, metal additive manufacturing has consistently focused on the core elements of manufacturing to improve efficiency and reduce costs, evolving from single-laser point scanning to multi-laser point scanning and eventually to area laser printing. From single-machine binder jetting sand mold printing to "multi-machine + casting + machining" rapid delivery, the manufacturing efficiency of additive manufacturing has seen hundreds of times of improvement, and costs have significantly decreased to levels acceptable to production facilities. This has led to widespread adoption, making it a new and powerful driving force for the high-quality development of the casting industry.

3DPTEK(三帝科技), leveraging its proprietary core technologies in 3D printing equipment, materials, and processes, actively promotes the large-scale application of 3D printing in industrial production, empowering casting through 3D printing (3D casting). By acquiring foundries and integrating the "3D printing + casting" process, 3DPTEK(三帝科技) not only ensures autonomous control over core equipment but also customizes corresponding binders according to the casting requirements of users. Moreover, the company provides process packages and on-site operation training validated by downstream foundries, offering a comprehensive solution across the entire industrial chain. This approach genuinely assists foundries in using 3D printing technology to produce satisfactory products, aiding their transformation and upgrading towards green, intelligent, and high-end casting.

3DPTEK(三帝科技)'s unique combination of "SLS coated sand molding process + 3DP resin sand molding process" enables the high-precision, high-strength integrated casting of complex structural components (such as large-sized, thin-walled, and fine tubular parts). This process has been selected as a typical application scenario by the Ministry of Industry and Information Technology.

The 3DP sand casting process, which eliminates the need for molds, allows for the high-precision, high-strength integrated casting of large-sized, thin-walled, and complex structural components. This process is characterized by short production cycles, clear advantages in small-batch production, flexible design, timely modifications, and cost reduction. It also improves the production environment, reduces labor intensity, and saves labor costs, making the process greener and smarter.

The SLS wax pattern precision casting process, which also eliminates the need for molds, achieves high-precision, high-strength integrated precision casting of complex structural, thin-walled, and large-sized products. This process is particularly advantageous for short production cycles and small-batch production. The PMX crystal wax pattern precision casting process significantly shortens processing cycles, reduces production costs, and eliminates the need for molds and supports, with no warping or deformation during the forming process, reducing post-processing steps while maintaining high forming accuracy. The company's independently developed materials exhibit strong volatility and low ash content, reducing casting defects and increasing yield rates. This technology has been successfully applied in the casting industry.

3DPTEK(三帝科技)'s 3D casting technology is gradually demonstrating its unique application value across various fields. In aerospace, the technology is used for manufacturing engine components, spacecraft structures, and power devices, effectively addressing the challenges of forming ultra-large-sized, multi-dimensional curved surfaces, and complex structural workpieces. The technology offers unmatched advantages in small-batch, large-sized mold manufacturing and iterative upgrades of molds in special industries compared to traditional manufacturing processes. In the energy and power sector, 3D casting technology is applied in the manufacturing of large-sized, pressure-resistant complex cavity structural components and large-sized, thin-walled, lightweight parts.

One client required a giant, large planar, thin-walled structural component that was challenging to meet with traditional welding and casting processes. Using 3DPTEK(三帝科技)'s 3D casting process, two finished products were delivered within 45 days, with dimensions of 1800mm × 2000mm and a wall thickness of 5.5mm.

Another client needed a massive 1.25-ton aluminum alloy casting, with a lower diameter of 900mm, an upper diameter of 1200mm, and a height of 1850mm. Traditional manufacturing methods were costly and time-consuming, and achieving the required complex structure was difficult. However, using 3DPTEK(三帝科技)'s 3D casting process, delivery was completed in just 15 days, saving the client significant time and costs.

3DPTEK(三帝科技)'s comprehensive 3D casting solutions have now matured into commercially viable applications in casting production. Foundries that were early adopters of 3D casting have established green, flexible, high-end rapid casting capabilities, doubling their production efficiency, capacity, and revenue, and successfully transforming into green rapid casting model factories.

At this year's Casting Expo, 3DPTEK(三帝科技)'s self-developed 4-meter large-scale 3DP sand molding machine, 3DPTEK-J4000, won the "National Casting Equipment Innovation Award." The company is currently running a promotional campaign, offering a "Million Subsidy, Order Now and Save" discount on new products. During the exhibition, those who pre-order the 3DPTEK-J4000 or larger models will receive a discount of 100,000 CNY, limited to 10 orders. Act quickly if you are interested!

This equipment breaks through the traditional size limitations of machining, allowing the creation of sand molds up to 4 meters in size. It innovatively employs flexible regional forming technology without a sand box, breaking the trend where larger forming equipment typically means higher costs. The 4-meter equipment is priced comparably to 2-meter equipment, enabling the cost-effective and efficient production of ultra-large-sized sand molds with shorter delivery times and lower unit costs. The printing platform can also be customized and expanded according to user needs, meeting production demands of 10 meters or more (6-meter, 8-meter, and 10-meter equipment are currently available for pre-order). Meanwhile, the company offers open-source material processes that can be adjusted on-demand for users, along with high-performance resin binders, curing agents, and cleaning agents to ensure forming quality and stability.

This exhibition will continue until July 7 at the Shanghai National Exhibition and Convention Center. Visit 3DPTEK(三帝科技)'s booth at 4.1H Hall, 4F05, for more information and exchanges.
