According to the Resource database, the University of Hanyang’s University Research team recently published its innovative research results: they intelligently used overcurrent defects in 3D DLP printing to successfully develop the Anisotrope membership structure with gecko features.
This unexpected discovery provides new technical ideas for flexible robots, biomedical equipment and other areas. At present,This study was published inMicrosystems and nano-engineeringin the magazine.
Transformation of defects into characteristics
In conventional DLP printing, the additional caused by excessive penetration of light is often considered a defect of quality. But the research team transformed this “defect” into a controllable advantage by accurately controlling the printing direction and the exposure time – tilting the microscopic structure of the pillar to a specific angle.
This bionic design is similar to the structure of the hairs of the gecko soles: when the pressure is applied in a specific direction, it can produce strong adhesion and can easily break with a slight turn.
Technological breakthroughs and application perspectives
The research team used double-molding technology for post-processing of the printed structure, and the final equipment obtained presented directional membership characteristics similar to the soles of natural geckos.
Test data show that this bionic adhesion structure shows important technical advantages: membership resistance is 40% higher than that of traditional methods, the manufacturing process has rationalized 3 key processes and can stable the surfaces of various materials such as glass and silicone.
In the practical application of the mechanical tightening module, this structure has passed the loss -free manipulation test of electronic precision components, checking its practical value in the field of precision manufacturing.
This innovative approach was successfully applied to the prototypes of mechanical tightening modules and has demonstrated excellent performance in electronic handling tests of precision components. “This technological breakthrough proves that” defects “review in the manufacturing process can lead to a disruptive innovation,” said the team leader.
Technology is currently requiring international patents and the research team plans to cooperate with manufacturers of medical aircraft to develop a new generation of surgical robot entry system. This discovery also provides a new paradigm for the development of 3D printing processes-that is to say to carry out a simple manufacture of special functional structures by actively using the characteristics of inherent processes rather than completely eliminating defects.
