Problems solved by technology

However, the above-mentioned layered manufacturing method requires a high-power energy source and a metal powder with a small particle size, and the cost of equipment and raw material preparation is relatively high, so it is difficult to popularize and apply it.
In addition, spheroidized crystallization, local sintering and thermal deformation are prone to occur during the powder fusion process. The related technologies and theories are not yet mature, and further research is needed.
