This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,735.

Summary of the Inventive Concept

Improved systems and methods for additive manufacturing of medical devices, enabling production of customized devices with enhanced properties and quality control.

Background and Problem Solved

The original patent disclosed systems and methods for manufacturing 3D printed medical devices, but was limited by the inability to produce devices with customized flex modulus, color properties, and surface finish. The new inventive concept addresses these limitations by introducing multi-material extrusion, hybrid 3D printing, and real-time monitoring to enhance the manufacturing process.

Detailed Description of the Inventive Concept

The enhanced systems and methods for manufacturing 3D printed medical devices comprise a multi-material extrusion mechanism that enables concurrent deposition of varying stiffness filaments at adjustable blend ratios, allowing for the production of medical devices with customized flex modulus and color properties. Additionally, a hybrid 3D printing process combining Fused Deposition Modeling (FDM) and Stereolithography (SLA) techniques is employed to achieve enhanced surface finish and mechanical properties. Furthermore, a real-time monitoring module enables in-process quality control and adaptive adjustment of printing parameters to ensure consistent product quality. The resulting 3D printed medical devices exhibit improved biocompatibility, reduced thrombogenicity, and enhanced resistance to biofouling.

Novelty and Inventive Step

The new claims introduce novel and non-obvious features, including the multi-material extrusion mechanism, hybrid 3D printing process, and real-time monitoring module, which provide significant improvements over the original patent. These features enable the production of customized medical devices with enhanced properties, thereby overcoming the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different 3D printing techniques, such as Selective Laser Sintering (SLS) or Binder Jetting, or the incorporation of additional materials with varying properties. Variations could also include the use of different monitoring modules or post-processing techniques to enhance the device's properties.

Potential Commercial Applications and Market

The enhanced systems and methods for manufacturing 3D printed medical devices have significant commercial potential in the medical device industry, particularly in the production of customized catheters, implantable stimulation leads, and other medical devices. The target market includes medical device manufacturers, hospitals, and research institutions.
