Problems solved by technology

But at present, the commonly used powder feeders have problems such as low powder feeding accuracy, low powder utilization rate, easy clogging, and inability to withstand high power.
[0004] A set of stable and practical powder feeding head is the key to determine the forming accuracy and forming efficiency of 3D printing. Currently, the mainstream powder feeding heads in the market have many deficiencies in powder feeding accuracy and high power capacity. In actual processing, it can stably withstand 3000W The fiber laser has fewer powder feeding heads, and there are large deficiencies in powder feeding accuracy and powder jet stiffness
