October 19-22, 2025: The 7th Asia Powder Metallurgy Congress & Exhibition (APMA2025) was successfully held in Qingdao, Shandong. Jointly organized by the China Powder Metallurgy Industry Technology Innovation Strategic Alliance (CPMA) and the Chinese Society for Metals (CSM), the event brought together leading experts and corporate representatives from the global powder metallurgy field.

3DPTEK's independently developed BJ Binder Jetting metal/ceramic printer, the 3DPTEK-J400P, received the "Powder Metallurgy Innovation Award." Additionally, Dr. Zong Guisheng, Chairman of 3DPTEK and Director of the CPMA's 3D Printing Special Committee, was honored with the "Powder Metallurgy Outstanding Contribution Award."

As a key participant, 3DPTEK was deeply involved in multiple agendas. Dr. Zong Guisheng chaired the Additive Manufacturing sub-forum and delivered an invited report titled "Binder Jetting Manufacturing," sharing cutting-edge practices of this technology in promoting efficiency and cost reduction within the powder metallurgy industry.

In his report, Dr. Zong pointed out the challenges of traditional powder injection molding, such as high mold costs, long development cycles, and limitations on product size. Through Binder Jetting (BJ) 3D printing technology, 3DPTEK has achieved mold-free manufacturing, rapid prototyping of complex structures, and production of large-sized parts, effectively helping the industry reduce costs and improve efficiency. Currently, this technology has achieved large-scale application in fields including 3C electronics, automotive, aerospace, AI chip heat dissipation, and liquid cooling systems.

BJ Binder Jetting Metal/Ceramic Printing System Enables Efficient and Precision Manufacturing

3DPTEK has systematically mastered the complete set of key technologies for BJ Binder Jetting metal/ceramic forming, encompassing equipment, materials, and processes. Its series of printing equipment (3DPTEK-J160R/J400P/J800P) integrate precise powder feeding, high-density powder spreading, and high-precision inkjet control systems, effectively addressing the challenges of spreading small particle size powders. The systems support high-resolution printing from 400 to 1200 dpi, achieve a maximum dimensional accuracy of ±0.1 mm, and offer a maximum build volume rate of 3600 cc/h.

Regarding material systems, the company has developed over 20 process formulations, including water-based (environmentally friendly) and solvent-based (high-efficiency) types, covering various metal materials such as stainless steel, titanium alloy, and high-temperature alloys, as well as ceramic and non-metallic materials like silicon carbide. Through systematic debinding and sintering process control, precise regulation of product shape and performance is achieved, with product properties meeting and partially exceeding international standards.

Leveraging the advantages of BJ technology—"high efficiency, low cost, and no thermal stress"—3DPTEK has made significant breakthroughs in the thermal management field, successfully achieving high-quality forming of composite materials like copper-diamond and copper-silicon carbide, with performance surpassing the MIM international standard. The company implements a differentiated equipment strategy: it provides research-grade equipment (3DPTEK-J160R) to research institutions and chip design companies for rapid prototyping and thermal design verification; for industrial users, such as those in liquid-cooled servers, it offers integrated industrial solutions (equipment + specialized powders/binders + process packages), helping customers shorten process development cycles by over 60%.

SLM Laser Metal Printing and Gradient Material Systems Push Technological Boundaries

In addition to Binder Jetting technology, 3DPTEK has independently developed a range of metal printing systems, including Selective Laser Melting (SLM) equipment (AFS-M120/M400), gradient metal equipment (AFS-M120X(T)), and multi-material integrated additive-subtractive equipment (AFS-M300XAS). Process development for various materials including stainless steel, titanium alloy, aluminum alloy, tool steel, cobalt-chromium alloy, and nickel-based alloy has been completed.

Among these, the AFS-M120X(T) can achieve continuous and precise gradient feeding of two or more metal materials, suitable for research on composite metal material properties. The AFS-M300XAS supports gradient combinations of up to 4 materials, enabling continuous gradient variation in the horizontal direction and material switching or gradual transition in the vertical direction. It holds broad application prospects in high-throughput material development, aerospace, automotive, medical, and mold manufacturing fields.

3DPTEK consistently emphasizes industry-academia-research collaboration, maintaining close partnerships with institutions like Shenzhen Polytechnic University, Shenzhen Tsinghua University Research Institute, Shanghai Jiao Tong University, and University of Science and Technology Beijing. These efforts continuously drive basic research and the commercialization of results related to BJ technology in materials, processes, and applications, facilitating the large-scale application of BJ in areas such as industrial molds, high-end cutting tools, precision components for 3C electronics, and large, complex-shaped ceramic products.
