Fig.1 Schematics of setups for laser-induced forward transfer (LIFT) technology (a) and laser-induced backward transfer (LIBT) technology (b); and dispersion and deposition processes (c) and explosive transfer process (d) of laser-induced donor material[14] (This schematic simplifies the optical path to highlight the core transfer mechanisms. In practical implementations of laser-induced transfer (LIT) technology, a laser focusing optical path is always involved to ensure energy concentration and transfer precision)
