Overview
Following attention to the previous high-resolution micro/nano 3D printer, Guangyunda upgraded its high-resolution micron-scale 3D printer. Guangyunda is one of the earliest companies to enter the industrial 3D printing field in the Chinese market and has combined its device development and manufacturing experience for this update.
Key improvements
1. Exposure accuracy optimized to 5 μm. Based on theoretical analysis and experiments, a 5 μm optical precision provides a greater depth of focus than 2 μm systems. Under conditions of increased layer thickness and larger exposure field, the 5 μm configuration achieves notably higher throughput than traditional 2 μm systems. Compared with the prior 7 μm model, the 5 μm option offers improved precision and, for layer thicknesses greater than 10 μm, delivers print quality comparable to 2 μm systems in most applications.
2. Build area expanded to 100 mm x 100 mm. Larger print areas are achieved through multi-field exposures, improving suitability for a wider set of applications and for small-part batch production. Higher native resolution (e.g., 4K vs. 2K) combined with tiled exposures increases total printable area while keeping the number of tiles relatively low.
3. Added preheating and thermal maintenance. For high-viscosity resins, raising resin temperature reduces viscosity and can improve print accuracy and success rate. The upgraded model uses large-area contact preheating to improve heat transfer efficiency and shorten setup time.
