Zusammenfassung:Transparent glass with metal mesh is considered a promising strategy for high performance transparent glass heaters (TGHs). However, the realization of simple, low‐cost manufacture of high performance TGHs still faces great challenges. Here, a technique for the fabrication of high performance TGHs is proposed using liquid sacrificial substrate electric‐field‐driven (LS‐EFD) microscale 3D printing of thick film silver paste. The liquid sacrificial substrate not only significantly improves the aspect ratio (AR) of silver mesh, but also plays a positive role in printing stability. The fabricated TGHs with a line width of 35 µm, thickness of 12.3 µm, and pitch of 1000 µm exhibit a desirable optoelectronic performance with sheet resistance (Rs) of 0.195 Ω sq−1 and transmittance (T) of 88.97%. A successful deicing test showcases the feasibility and practicality of the manufactured TGHs. Moreover, an interface evaporator is developed for the coordination of photothermal and electrothermal systems based on the high performance TGHs. The vapor generation rate of the device reaches 10.69 kg m−2 h−1 with a voltage of 2 V. The proposed technique is a promising strategy for the cost‐effective and simple fabrication of high performance TGHs. An inexpensive fabrication method for high performance transparent glass heaters (TGHs) by liquid sacrificial substrate electric‐field‐driven microscale 3D printing is presented. The manufactured TGHs exhibit excellent optoelectronic properties remarkable mechanical stability and environmental adaptability.
