摘　　要：在原有3D打印技术基础上,创造性地提出了"打印一加工"相结合的新型3D打印技术,它将很好地解决制造尺寸、制造速度、制造精度、制造成本等一系列问题。传统的送料结构仅能满足桌面级小型机的使用,因此必须研制一套与新型3D打印技术相配套的供料设备,文中参照注塑行业螺杆式挤出机的设计方法,探寻一种适用于3D打印的供料挤出螺杆设计方法,并对主要参数进行计算,为接下来总体供料设备的制造和应用奠定基础。Based on tile origi,lal 3D printing, this paper proposes a creative 3D printer technology which combines the traditional 3D printing with CNC cutting. The new technology can solve a series of problems that exist in the traditional 3D prinling, such as prodnct size, manufacture speed, machining precision and manufacturing cost. The feeding device of lraditional 3D printing can only satisfy the desktop 3D printer, so we should invent new feeding deviee. We design a new feeding device by reference to the extrusion screw used in tbe injection molding industry. This paper briefly expounds the calculation method of 3D printing feed screw to lay the foundation for the manufacture anti application of feeding equipment.
