Problems solved by technology
However, this prior art can only produce a control effect after contact, so the damage caused by the collision between the printer platform and the resin tank cannot be avoided, and in the process of printing photocuring, the cured part must be in contact with the resin tank, and the relationship between the two cannot be guaranteed. There is a layer-thick gap between them, making it impossible to actually print

The invention discloses a 3D printing equipment position control device and relates to the field of 3D printing. The 3D printing equipment position control device comprises a working table, an opticalmirror, projector equipment, a Z-axis moving platform and a resin tank, the optical mirror and the projector equipment are arranged below the working table, the projector equipment projects upwards,the Z-axis moving platform and the working table are movably connected, the resin tank and the working table are fixedly connected, flexible compressing mechanisms are arranged on the two sides of theresin tank, a printing platform is arranged above the resin tank, the printing platform, a tension pressure sensor and a flexible regulation mechanism are sequentially connected, the flexible regulation mechanism is connected to the Z-axis moving platform, and both the projector equipment and the tension pressure sensor are connected with a controller. The device accurately controls the gap between the printing platform and the resin tank, improves the printing accuracy of the product in the Z direction, avoids the phenomenon that resin is not cured on the printing platform, avoids the collision damage between the printing platform and the resin tank, and reduces the difficulty of manual debugging.
Description
Technical field [0001] The present invention relates to the field of 3D printing, in particular to a device for position control of 3D printing equipment and a method of use thereof. Background technique [0002] Light-curing 3D printing is one of the earliest 3D printing methods and the current mainstream 3D printing method. Light curing 3D printing is mainly divided into three types: SLA (stereolithography), DLP (digital light projection) and Polyjet (polymer jet). The 3D printing methods of SLA and DLP are divided into two types: top-down printing platform and bottom-up printing. The bottom-up 3D printing method of the printing platform has the advantages of saving consumables, avoiding air bubbles, and easily controlling the layer thickness. However, traditional SLA or DLP bottom-up 3D printers lack the means to control the distance between the printing platform and the bottom of the resin tank, which is prone to collision between the platform and the resin tank or the gap ...
