Abstract: The disclosure provides a power management method. The power management method is applicable to an electronic device. The electronic device is electrically coupled to an adapter, and includes a system and a battery. The adapter has a feed power. The battery has a discharge power. The power management method of the disclosure includes: reading a power value of the battery; determining a state of the system; and discharging power to the system, when the system is in a power-on state and the power value is greater than a charging stopping value, by using the battery, and controlling, according to the discharge power and the feed power, the adapter to selectively supply power to the system. The disclosure further provides an electronic device using the power management method.

Abstract: A nozzle adjustment device for a three-dimensional forming equipment assembly includes a first guiding block, a second guiding block, and a moving block. The first guiding block has a first inclined surface and a first bottom surface which is parallel to a printing platform. The first inclined surface and the first bottom surface form an acute angle therebetween. The second guiding block has a second inclined surface. The moving block is located between the first guiding block and the second guiding block. The moving block has a third inclined surface, a fourth inclined surface, and a second bottom surface. The second bottom surface is parallel to the printing platform, and has a nozzle disposed thereon.

Abstract: The present invention provides a residue removing device for removing residues in a partition plate, and a related 3D printer for use on a working platform. The partition plate e.g. of a 3D printer has a plurality of openings arranged in an array, and residues may be filled in the openings. The residue removing device includes a base plate and a plurality of jutting pins disposed on an upper side of the base plate. The jutting pins are arranged in an array corresponding to the openings array such that the jutting pins are capable of being inserted into the openings, in order to easily remove the residues in the openings of the partition plate.
