Bright Laser Technologies' (metal 3D printing, specifically the BLT-A160D printer, is instrumental in crafting the world's inaugural flexible robotic system for minimally invasive neurosurgery. The MicroNeuro, developed by the Centre of Artificial Intelligence and Robotics (CAIR), integrates cutting-edge technologies like flexible endoscopy, AI, and augmented reality navigation, addressing challenges associated with delicate brain tissue. BLT's metal 3D printing, particularly the multifunctional distal head caps, proves pivotal in achieving convenience, flexibility, and structural compactness for the MicroNeuro, setting a new standard in neurosurgical robotics.


In a groundbreaking stride, Bright Laser Technologies (BLT) is at the forefront of revolutionizing neurosurgery through its metal 3D printing technology. The BLT-A160D printer plays a pivotal role in crafting the MicroNeuro, the world's first flexible robotic system designed for minimally invasive brain surgery. Developed by the Centre of Artificial Intelligence and Robotics (CAIR) at the Hong Kong Institute of Science & Innovation, Chinese Academy of Sciences, the MicroNeuro amalgamates state-of-the-art technologies to redefine neurosurgical procedures.

The MicroNeuro is a testament to innovation, combining multilevel flexible endoscopy, high precision control, augmented reality surgical navigation, and artificial intelligence. Its standout feature, the 'digital twin' capability, facilitates real-time matching of brain tissue structure and surgical tools, enhancing the surgical process's intuitiveness. This sophisticated blend of technologies addresses the complexities of fragile brain tissue and confined spaces, overcoming the limitations of traditional hand-eye-brain operations.

BLT's metal 3D printing prowess, particularly the BLT-A160D printer, is a linchpin in the production of MicroNeuro's multifunctional distal head caps. Crafted from SUS 316L stainless steel, these components serve a vital purpose in fixing and installing image units, lighting units, instrument channels, and other crucial elements. The intricate design, featuring wall thicknesses as low as 0.15 mm, showcases the superiority of metal 3D printing over conventional methods.

BLT-A160D's high throughput capabilities shine through, enabling the fabrication of 1190 pieces of multifunctional distal head caps in a mere five hours. The consistent product quality achieved across multiple batches and systems demonstrates the reliability of BLT's metal 3D printing technology. The post-processing polishing by BLT ensures that all surface roughness requirements are met, contributing to the overall efficiency and quality of the mass-produced distal structures.

CAIR envisions the integration of irregular channels into the multifunctional distal head, emphasizing the unique capabilities of metal 3D printing in achieving this feat at a low cost and with high precision. The success of BLT's collaboration extends beyond head caps, encompassing the development of other critical components like flexible endoscopes, rigid sheath endoscopes, and water guide tubes.


BLT's 3D printing technology emerges as a transformative force in the field of neurosurgery, with the MicroNeuro setting new standards for minimally invasive procedures. The synergy between cutting-edge technologies and BLT's metal 3D printing prowess marks a significant advancement in the realm of robotics-assisted neurosurgery. As the MicroNeuro paves the way for future innovations, BLT's role in shaping the landscape of medical robotics becomes increasingly prominent.
