    • Disclosed is an apparatus for depositing a particulate marking material onto a substrate, comprising (a) a printhead having defined therein at least one channel, each channel having an inner surface and an exit orifice with a width no larger than about 250 microns, the inner surface of each channel having thereon a conductive polymer coating; (b) a propellant source connected to each channel such that propellant provided by the propellant source can flow through each channel to form propellant streams therein, the propellant streams having kinetic energy, each channel directing the propellant stream through the exit orifice toward the substrate; and (c) a marking material reservoir having an inner surface, the inner surface having thereon the conductive polymer coating, the reservoir containing particles of a particulate marking material, the reservoir being communicatively connected to each channel such that the particulate marking material from the reservoir can be controllably introduced into the propellant stream in each channel so that the kinetic energy of the propellant stream can cause the particulate marking material to impact the substrate.
    • 公开了一种用于将颗粒状标记材料沉积到基底上的装置,包括(a)其中限定有至少一个通道的打印头,每个通道具有内表面和宽度不大于约250微米的出口孔,内部 每个通道的表面上具有导电聚合物涂层; (b)连接到每个通道的推进剂源,使得由推进剂源提供的推进剂可以流过每个通道以在其中形成推进剂流,所述推进剂流具有动能,每个通道将推进剂流引导通过出口孔朝向基底; 和(c)具有内表面的标记材料储存器,所述内表面上具有导电聚合物涂层,所述储存器包含颗粒标记材料的颗粒,所述储存器通信地连接到每个通道,使得来自储存器的颗粒标记材料 可以可控地引入每个通道中的推进剂流中,使得推进剂流的动能可导致颗粒状标记材料冲击底物。
