Conducting additive manufacturing tests on metal materials such as copper, aluminum, high entropy alloys, and nickel titanium alloys using blue light, and studying the effects of blue light laser on the porosity, microstructure, mechanical properties, and other properties of printed aluminum. Provide feasible data for the additive manufacturing technology of non-ferrous metals in aerospace, rail transit, military equipment and other fields using blue light additive manufacturing.

Using blue light laser as an excitation source to irradiate specific phosphors. After absorbing blue light energy, the fluorescent powder will be excited to a higher energy level state, and then release energy in the form of visible light during the de excitation process, emitting light of different colors. By selecting the appropriate type and formula of fluorescent powder, the light emitted by the fluorescent powder is mixed with the remaining blue light, ultimately presenting white light in human visual perception.
By utilizing the advantages of high absorption rate and uniform energy distribution of blue semiconductor lasers, materials can be rapidly heated to obtain a uniform temperature distribution.
