Problems solved by technology

[0004] However, the existing rapid prototyping machines are complex in structure and cumbersome to operate, and they all use linear coordinate axis linkage feed, which can keep the speed of linear motion in the plane uniform, but for the interpolation problem in the linkage feed in curved motion, it makes the Extruder runs at uneven speeds making it difficult to maintain a consistent extruded material
