Why this company matters

3DPAction is a specialized medical 3D printing subsidiary of SANDI Technology, focused on customized rehabilitation devices including titanium hearing aids, digital dentistry solutions, orthotics, and prosthetics. It was founded in 2014 by Dr. Zong Guisheng, who built China's first industrial-grade 3D printer in 1993 and earned one of the world's first PhDs in 3D printing from UT Austin in 1991. The company operates an integrated end-to-end platform combining multiple additive manufacturing technologies with complete medical device manufacturing capabilities.

The company's core technologies span metal and polymer binder jetting (BJT) and powder bed fusion (PBF-LB), including selective laser sintering (SLS) and selective laser melting (SLM). It develops the HW-P110 binder jetting printer and the HW-S4040 SLS printer. A key differentiator is the ability to produce titanium hearing aid shells with wall thickness down to 0.15mm, enabled by its proprietary multi-material 3D printing processes. The company holds ISO 13485 certification and can produce devices certified under FDA, CE, and China Class II standards.

3DPAction targets medical institutions, dental clinics, implant centers, and rehabilitation hospitals. It acquired Shenzhen Shuanglong Dental Research, which holds EU CE, US FDA, and China Class II medical device certificates and distributes products in over 30 countries. The parent company SANDI Technology is designated a national specialized 'small giant' enterprise and operates more than 120,000 square meters of facilities. The medical subsidiary holds 14 medical device registration certificates and 27 medical device-related patents.

The company's primary competitive advantage is being the first in China to obtain a Class II medical device registration certificate for 3D printed customized titanium alloy hearing aids from the State Drug Administration. This regulatory milestone, combined with SANDI's unique position as the only Chinese company mastering four core 3D printing technologies (SLS, SLM, 3DP, BJ), creates a strong moat in the mid-to-high-end medical device segment. However, competition from established players like UnionTech, BLT, and Farsoon Technologies in dental and medical 3D printing remains significant.
