Abstract: A cell growth promoter and an application thereof are provided. The invention adopts Fe2+ and ovalbumin to form a Fe2+-ovalbumin (OVA) compound to promote ovalbumin cell endocytosis, the cell growth promoter can maintain cell growth in an environment free of amino acids, promote cell proliferation in an environment with amino acids; and, the Fe2+-OVA compound can replace expensive animal serum albumin in cell culture, the cell growth promoter has a significant effect on improving cell viability and is low cost.

Abstract: A laser-solid-forming manufacturing device includes a laser emitter, a magnetic field generator, and a forming platform. The laser emitter emits a laser beam which acts on a feedstock to form a molten pool. The magnetic field generator includes a spiral copper coil, a first electrode and a second electrode. The spiral copper coil is formed by spirally winding a copper tube. The first and second electrodes are arranged at respective ends of the copper tube and are used for loading a voltage to generate a magnetic field in the spiral copper coil. At any time, the spiral copper coil sleeves an action point of the laser beam and the feedstock. A corresponding laser-solid-forming manufacturing method is also presented.
