Advantage of the present utility model is:

(1), this telecontrol equipment is provided with separate driving shaft and sliding axle, by the compound motion on same axle being decomposed into the simple motion of 2 axle independent operatings, X, Y-direction are not interfere with each other, reduce motion modulation, stability while having increased the motion of 3D printing head, has improved the precision that 3D prints.

(2), compare the telecontrol equipment that simultaneously makes sliding axle and turning cylinder of same axle, this device antijamming capability is strong, when 3D printer works long hours, also can keep high accuracy print.

(3), have enough areas on the surrounding frame of print platform, therefore there is very strong flexibility, can load on demand optical axis, guide rail, and servo with parts such as gratings, realize closed-loop control, further improve transmission accuracy and prevent from losing step.

(4), the X-axis drive motors of this telecontrol equipment and Y-axis drive motors, be located at print platform one side, be respectively equipped with two driven bearings at the offside of print platform X, Y-direction, by the belt being connected with two driven bearings, two motors drive respectively the motion of X crossbeam and Y crossbeam, realize 3D printing head stable back and forth movement on twocouese, reduced bi-directional printing error.

(5), because this telecontrol equipment is provided with separate driving shaft and sliding axle, stack and the enlarge-effect of parts errors are avoided, in the situation that part design, installation accuracy, control circuit are good, X, Y-axis positioning precision can easily reach 1～3 μ m, and precision index substantially exceeds the required precision of fusion sediment type 3D printer.
