Abstract
With the development of emerging technologies, reverse engineering technology has been developed rapidly in recentyears, including the 3D printing technology.And now 3D printing technology has beenwidely used in the field of mechanical manufacturing. To improve the application level of rapid prototyping technology and fast-efficient processing has become a project of 3D printing technology.
To analysis the development of the 3D printer,we put forward the overall plan of design of the delta type FDM3D printer based on the ultimate principle, and to design the mechanical structures of the 3D printer, including frame design, transmission design, feeding device, control element selection. Furthermore the key parts have been checked. Printing precision has been improved by improving the accuracy of nozzle; With form of combining the sliding screw and rolling guide in the transmission part is not only ensure the transmission accuracy, improved the transmission efficiency, used the linear stepper motor that directly connectedwith screw but also made the response more accurate and fast.with no intermediate transmission links, the mechanical structure is simplified. and made a higher precision.
Keywords: 3D printing technology; parallel machine tool; transmission mechanism; stepping motor; nozzle
