Coaxial Printing Monitoring UV Light Engine

The CPM09 (Coaxial printing monitoring UV light engine) adopts a coaxial optical path design, and the camera collects the image in real time when the UV light engine is digitally exposed. When exposing printing, monitor the clarity and brightness of the image through the camera; Precision manufacturing, biomedicine, advanced electronics and other fields have disruptive potential, especially suitable for small batch, high complexity, multi-material micro-nano device needs.

Product features:

Real-time monitoring and closed-loop control

The integrated CMOS camera captures the light-curing status of the printed layer (e.g., resin shrinkage, bubble defects) in real time. It can be combined with AI algorithms (such as convolutional neural networks) to automatically analyze the image and feedback to adjust parameters (such as exposure time, light intensity, sharpness) to avoid interlayer misalignment or collapse. Application scenario: When printing microfluidic chips, real-time detection of channel deformation and compensation of exposure strategy.

Dynamic light field modulation

Through the synergy of the DMD and the coaxial optical path, grayscale exposure or multifocal light field can be realized, supporting continuous printing of complex gradient structures (such as biomimetic vascular networks). For example, in a single-layer exposure, the local curing depth can be adjusted by a grayscale mask to reduce the need for post-processing.

Compatible with a wide range of magnification lenses

According to the requirements of process parameters, different lenses can be selected to achieve different printing formats, and a single exposure area can reach centimeter level, combined with multi-UV light engine splicing technology to achieve large-area microstructure arrays (such as mass production of flexible electronic circuits).
