A technical field of 3D printing device or rapid prototyping machine, particularly a workpiece anti-deformation method for a 3D printer. The printer comprises a lifting platform (1) having a working platform (2) provided thereon. The upper surface of the working platform (2) is provided with a plurality of vacuum suction holes (3), and negative pressure lower than the atmospheric pressure is generated in the vacuum suction holes (3). After being molded, the structure of the bottommost layer of a printed workpiece is sucked on the upper surface of the working platform by plugging part of vacuum suction holes (3) in the working platform (2). When a vacuum air suction device is at work, the vacuum suction holes (3) are in a vacuum air suction state. After the bottommost layer of the workpiece is printed by the 3D printer, the bottommost layer is sucked on the upper surface of the working platform (2) by the suction effect of the vacuum suction holes (3), so that the printed structural layer is effectively prevented from deformation, Therefore, the method has high feasibility and strong practicability. |
