Beijing Balance Medical Technology Co., Ltd (Bairen) has adopted Formlabs stereolithography (SLA) 3D printing ecosystems, utilizing a range of flexible and general purpose resins to print heart valve models and anatomical organ models.

As a pioneer in domestic bioprosthetic valves, Bairen's products span three major areas:

• Heart valve replacement and repair
• Interventional treatment of congenital heart diseases
• Surgical soft tissue repair

By adopting 3D printing with Formlabs Form 4 Generation 3D printers, Bairen can provide more intuitive and efficient support for customized valve research and development, design validation, and clinical evaluation, accelerating the iteration of medical innovations and benefiting more patients.

The human heart beats about 100,000 times a day, and each beat relies on the heart valve to open and close with precision.

As a critical structure for maintaining normal blood circulation, heart valves must satisfy both intricate anatomical fit and mechanical performance requirements. Given the individual differences among patients in terms of valve structure, pathological conditions, and physiological status, the research and development of medical devices faces increasingly complex challenges when it comes to design validation.

Due to differences in age, physical condition, and other factors, heart valve diseases are often highly individualized. By acquiring cardiac structural data through medical imaging and combining it with 3D printing to produce physical models, physicians and R&D teams can more intuitively observe valve structure, lesion areas, and anatomical variations to provide a more direct basis for personalized treatment planning. 

Individual valve variations result from both congenital developmental anomalies and acquired pathological changes. Therefore, in heart valve R&D, models must not only accurately reproduce complex structures but also approximate the performance characteristics of real tissue.

Bairen did technical validations on Form 4 Generation 3D printers, finding the precision, reliability, and comprehensive material portfolio met their requirements for heart valve R&D. 

With Form 4 and Form 4L 3D printers and the extensive Formlabs material library, medical R&D teams gain greater flexibility in model validation. By applying materials with varying durometers, such as Silicone 40A Resin, Flexible 50A Resin, and Flexible 80A Resin, teams can more directly observe the structural performance of valve models under different design approaches.

In addition, Bairen uses White Resin and Clear Resin to print related organ models, helping R&D teams more clearly observe internal structures and blood flow patterns, offering more reliable references for valve design, performance evaluation, and fluid dynamics analysis.

From replicating complex anatomy to simulating material properties and visualizing internal conditions, Form 4 and Form 4L are helping Bairen's R&D team establish a more intuitive and multidimensional validation approach.

3D printing is a vital bridge connecting digital design with physical validation, enabling medical device manufacturers to deliver greater precision and personalization.

From heart valve R&D to preoperative planning, medical education, and personalized treatment exploration, 3D printing makes it possible to create physical models of complex human structures, enabling physicians and researchers to provide more precise medical solutions.

This collaboration between Formlabs and Bairen validates the real-world applicability of additive manufacturing in the medical field and sets a new benchmark for healthcare innovation.
