In article number 1903872, Jianguo Guan, Martin Pumera, and co‐workers report a 3D‐printed millimeter‐scale motor (3DP‐motor) that moves fast over a long range (tens of meters) through the Marangoni effect induced by asymmetrically releasing ethanol, which acts as the propellant. During its navigation, the 3DP‐motor can carry and slowly release TiO 2 /Pt Janus micromotors that can be catalytically activated and propelled by light illumination, moving locally for tens of millimeters while acting as photodegradation agents.
