3D printing of common metals is highly challenging because metals are generally solid at room conditions. Copper and gold pillars are manufactured with a resolution below 5 μm and a height up to 2 mm, using laser-induced forward transfer to create and eject liquid metal droplets. The solidified drop's shape is crucial for 3D printing and is discussed as a function of the laser energy.
3D 打印常见金属极具挑战性，因为金属通常在室温下是固态的。使用激光诱导正向转移来制造和喷射液态金属液滴，可以制造出分辨率低于 5μm、高度达 2mm 的铜和金支柱。凝固液滴的形状对于 3D 打印至关重要，本文将其作为激光能量的函数进行了讨论。
