The casing of the 2nd one looks better..
Are they going to blue ball us against *raises fist at the heavens*The usual suspects at Zhuhai. These we have all seen before. The designations are on the placards.
The lightweight and integrated structure of the fan impeller blades manufactured with composite additive manufacturing.
In response to the design requirements of the integrated fan impeller blades, combined with the fiber-reinforced thermoplastic composite additive manufacturing technology, a data link based on complex three-dimensional integrated additive manufacturing is designed.
The manufacturing is completed by the method of carbon fiber resin pre-impregnation extrusion melt deposition. Compared with the traditional manufacturing method, the weight reduction is obvious, the manufacturing precision is greatly improved, and the structure and function can be integrated, providing a technical basis for low-load, multi-function and rapid trial production.
The structure is the overall structure of the composite fan impeller blades. The material is T800-grade carbon fiber reinforced polyetheretherketone thermoplastic composite material + additive manufacturing, with a specification of 500mm×500mm×300mm.

Single piece fan is interesting. But this piece seems small. Wonder if this method is limited to very small diameter engines.
i think, this is just the showpiece for airshow only.. this manufacturing method is definitely for big engines as well.
AECC Sichuan , AECC Chengdu and NPU Xian published complete research for additive manufacturing with composite for large engines.
Curious to see these papers!
i m really sorry sir, i have missed the main part..
in that paper, they were talking about next generation engine components with advanced laser processing technology and additive manufacturing.

Design and manufacturing method of multi-scale integrated load bearing thin-walled structure for application in next-generation aeroengine based on advanced laser processing technology
The multi-scale structure， composed of the macro skeleton， lattice and micro surface， represents a novel type of structure with potential for high performance， multifunctionality and lightweight design. Advanced laser processing technology not only enhances the manufacturing capacity of high-performance structures， but also provides possibilities for the manufacturing of new complex structures. After providing a brief overview of the current design and manufacturing techniques on macro skeleton， lattice and micro surface， this paper introduces a multi-scale structure design method for advanced laser processing technology. Taking the intermediate case of a turbine engine as an example， the main load-bearing skeleton is designed using topology optimization technology for additive manufacturing. The lightweight lattice design is carried out by filling manufacturable lattice in low-density areas in topology oiptimization or low-stress areas in the optimized model， resulting in a weight reduction of over 20% compared to the original design. Additionally， micro groove structures for drag reduction are designed on the surface of the airflow channel for ultrafast laser etching processing. Simulation results indicate that the micro grooves exhibit a drag reduction effect exceeding 10%. By exploring the multi-scale integrated structure design based on advanced laser processing technology， this study establishes a creative structural design procedure and offers a valuable approach for the development of next-generation aeroengine structures.
Eh, this is not a paper on the specific processes used for that composite single piece fan though? The specific process discussed here is for the engine casing.
