The invention discloses a slipper type 3D printer with parallel connecting rods and a movable platform, and belongs to the technical field of digital machining. The invention aims to solve the problems that a current 3D printer adopts a fixed platform, and a printing heat is driven by a stepping motor to move; this way is restricted by the wire speed of an extrusion head and the movement speed ofthe printing head, and accordingly wiredrawing phenomena frequently occur, resulting in high partial surface roughness of printed parts and influence on the printing quality. A printing platform is driven to move by the stepping motor through three groups of parallel connecting rods, and meanwhile the printing head is fixed; and the above problems are avoided, and the problem of the printing quality due to wiredrawing is solved. 本发明公开了种并连杆滑块式工作平台可动3D打印机，属于数字化加工技术领域。本发明针对目前的3D打印机采用平台不动、打印喷头通过步进电机带动下进行移动，这种方式受挤出头出丝速度以及喷头移动速度的限制，常出现拉丝现象，致使打印件部分表面粗糙度较高，影响打印质量的问题。以三组并连杆在步进电机的驱动下带动打印平台运动，同时打印喷头采用固定的方式，避免了上述问题的出现，解决了由于拉丝导致的打
