[HK3DPA] Members Astonished After Visiting Three Leading 3D Printing Companies in Shenzhen

On June 20, 2025, the Hong Kong 3D Printing Association (HK3DPA), in collaboration with Panda3dp.com, organized a cross-border industrial exchange event between Hong Kong and Shenzhen. A delegation of Hong Kong manufacturing professionals visited three standout Shenzhen-based companies—Microscale 3D printing specialist BMF PRECISION TECH, mass-production powerhouse HUAFAST, and CDMO innovator Guotai Optics Valley—resulting in eye-opening insights and lively exchanges.1

BMF PRECISION TECH: Micron-Scale 3D Printing Breakthroughs

Participants were amazed by BMF PRECISION TECH’s micro/nano 3D printing capabilities. The company demonstrated ultra-high-precision manufacturing—down to 2 μm resolution—which is unlocking new possibilities in fields such as endoscopy, vascular scaffolding, micro-connectors, and mobile 3C components.

One product that particularly impressed the visitors was Mofang’s 3D-printed ultrathin ceramic dental veneer. These veneers, measuring just 80 μm thick, can be mass-produced using proprietary printing technology. They require no tooth grinding and offer both cosmetic and restorative functions—tapping into a potential market valued in the tens of billions (CNY).

HUAFAST: A Thousand-Machine 3D Printing Farm

HUAFAST operates a massive FDM-based 3D printing farm with over 1,000 machines running simultaneously. Initially focused on printing consumer toys like articulated dragons, dragon eggs, and serpentine figures, the company is now increasingly receiving bulk orders for industrial components as well.

With the ability to deliver hundreds or even thousands of parts quickly, HUAFAST offers dramatic savings in both time and cost. This shift challenged the mindset of many Hong Kong manufacturers with decades of traditional production experience. While FDM print quality may not always match injection molding, speed and flexibility are clear advantages—making it viable for applications where tooling delays are prohibitive.

Guotai Optics Valley: Bridging Prototyping and Mass Production

A wholly owned subsidiary of Guotai Daming Precision Group (with thousands of employees and multi-billion CNY annual revenue), Guotai Optics Valley was founded in August 2023 and is headquartered in the Tian’an Cloud Valley Industrial Park, Guangming District, Shenzhen.

The company integrates multiple 3D printing technologies—metal, photopolymer, and nylon-based—with advanced machine tools from Japan and Switzerland, offering comprehensive support from R&D to mass manufacturing.

Its capabilities span:

· Prototyping: Dozens to hundreds of 3D-printed samples

· Joint R&D: Collaborative product development

· Mass production: Scaling to millions of parts

· CDMO model: A full-chain solution from concept to commercialization

This model exemplifies how additive manufacturing can seamlessly complement and even partially replace traditional manufacturing processes—ushering in a new era of smart, agile production.

Conclusion:
The visit left a strong impression on the HK3DPA members, who remarked on the synergistic convergence of 3D printing and traditional manufacturing. The trip not only demonstrated the commercial viability of additive manufacturing in both prototyping and production but also revealed strategic directions worth pursuing—especially for companies seeking faster turnaround, design flexibility, and integrated production workflows.

The message was clear: 3D printing is no longer an experimental add-on, but an emerging mainstream force in manufacturing.
