Jiří Samek is the founder and managing director of SinuCraft, a company focused on hybrid manufacturing systems that combine large-format additive manufacturing with CNC machining in a single platform. With more than 15 years of experience in industrial automation, robotics, and CNC control systems, he has worked across technical, application, and business leadership roles within the field of advanced manufacturing technologies. His background includes extensive work with industrial robots, CNC systems—particularly Siemens Sinumerik—and the integration of complex production lines across Europe. Today, his primary focus is the development of robotic CNC workstations that merge additive and subtractive processes into one coherent system. Jiří is particularly interested in leveraging new generations of high-stiffness robotic kinematics combined with industrial CNC control to enable high-precision machining on robotic platforms. His goal is to help redefine the perception of robots in manufacturing—from flexible handling devices to fully capable, production-grade CNC machines. His research and innovation interests center on hybrid manufacturing, digital twins, toolpath validation, and scalable machine architectures that increase flexibility while maintaining industrial accuracy and repeatability.

Hybrid Manufacturing

Presentation abstract: The presentation focuses on hybrid manufacturing, combining large-format additive manufacturing with CNC machining in a single integrated system. The key problem addressed is the gap between design freedom and industrial precision. While 3D printing enables complex geometries and efficient material usage, it often lacks the dimensional accuracy and surface quality required for functional parts. Traditional CNC machining provides precision but limits flexibility and scalability. A major technological shift now changes this paradigm: new generations of robotic kinematics significantly improve stiffness, repeatability, and path accuracy. Combined with advanced CNC control systems such as Siemens Sinumerik, robots are no longer limited to handling or rough processing tasks. They can now perform high-precision machining operations, making the robot a fully capable CNC machine. By integrating additive and subtractive processes on one robotic platform, manufacturers can print near-net-shape geometries and immediately machine them to final tolerances — without re-clamping or repositioning. This approach reduces production time, increases geometric freedom, and maintains industrial-grade precision. Applications include mold and tool manufacturing, aerospace and defense structures, and large composite or thermoplastic components where flexibility and accuracy must coexist.
