Abstract The complexities of fabrication techniques and the demand for high precision have posed significant challenges in mass production augmented reality (AR) waveguide combiners. Leveraging capabilities Polyjet 3D printing techniques, we developed a cost-effective method fabricating liquid geometric combiners AR applications, using silicone oil as medium. During design phase, optimized structure combiner to facilitate easier fabrication. Our proposed simplifies process by removing need complicated steps like dicing, layer bonding, polishing, which are usually involved traditional manufacturing techniques. We conducted optical simulations prototype our patented method, successfully demonstrated integration virtual images with real-world environment, thereby confirming its feasibility potential production.

Additive manufacturing (AM) or 3D printing wholly reinvents the making of metasurfaces/metamaterials and opens new opportunities from microwave to photonics. Conventionally, (engineered control electromagnetic waves strongly) have been challenging expensive fabricate using traditional techniques. However, AM provides an innovative turn in transforming design production such complicated surfaces. It renders flexibility, efficiency, economic viability fabrication process, enabling rapid prototyping customization. This will, therefore, enable times be shorter, reduce material waste, allow creation more much smaller metasurface structures than hitherto unattainable. Thus, drives strong advancements photonic, applications improved performance telecommunications, wearable sensors, imaging systems.

Abstract Augmented reality (AR) displays have provided users with immersive and see‐through experiences by overlaying virtual information onto the real physical environment. To realize combination of information, holographic plastics hold great promise as a waveguide combiner due to their high diffraction efficiency, transmittance, ease processing. However, adoption in practical AR is significantly limited reliability. Herein, subtle design longline‐like polymers multiple “hooking” sites reported that can undergo crosslinking after manufacturing. The resulting plastic reflection grating structures not only exhibits efficiency (> 80%), transmittance ( T 400 > 80%) low haze (<3%), but also shows improved stability under various environmental conditions (e.g., 60 °C oven, 80 water, & 90% relative humidity chamber), finally enabling high‐fidelity display three‐primary colors. proven critical, control group without inferior despite holding very similar parameters before This work establishes viable paradigm for developing reliable combiners explores new optical application chemical design.
