in the step 3), a first linear motor rotor positioned at one end of the printing beam slides in a first linear motor stator, so that the first moving supporting plate slides along a first linear guide rail; and a second linear motor rotor positioned at the other end of the printing beam slides in a second linear motor stator, so that the second moving supporting plate slides along the second linear guide rail, the sliding speeds of the first moving supporting plate and the second moving supporting plate are kept the same, and the first beam assembly and the second beam assembly synchronously drive the printing beam.
10. The printing beam and sanding beam common rail type driving method according to claim 9, characterized in that: the upper surface of the first cross beam is provided with a digital ruler, the bottom of the first moving supporting plate is provided with a reading head, in the moving processes of the sand paving beam and the printing beam in the steps 2) and 3), the numbers on the digital ruler are read through the reading heads in the first moving supporting plate at the end part of the sand paving beam and the printing beam, so that the position information of the sand paving beam and the printing beam is obtained, the reading head sends the position information of the sand paving beam and the printing beam to a controller of 3D printing equipment, the controller obtains the moving distance of the sand paving beam and the printing beam by calculating the difference value of the current position and the initial position, and then whether the moving distance of the sand paving beam and the printing beam exceeds the whole printing breadth is judged.
