PRINTING PLATFORM ADJUSTING SYSTEM AND ADJUSTING METHOD THEREFOR

摘要

A printing platform adjusting system of a three-dimensional printer, and an adjusting method therefor are disclosed. The printing platform adjusting system includes a printhead, a supporting frame, a printing platform, a driving unit, a distance sensor, a control unit, and a parallelism adjusting set. The printing platform has a plurality of detecting points. The distance sensor is configured to detect and obtain a plurality of detected vertical height values corresponding to the detecting points. The control unit controls the driving unit to drive the printhead to move, receives the detected vertical height values from the distance sensor, and converts the detected vertical height values into a plurality of adjusted vertical height values. The parallelism adjusting set includes a plurality of adjusting and fastening units configured to adjust a degree of parallelism between the printing platform and the horizontal movement plane of the printhead according to the adjusted vertical height values.
