3D PRINTING BOTTOM PLATE SYSTEM AND METHOD OF REPLACING 3D PRINTING CONTACT PLATE

摘要

A 3D printing bottom plate system comprises a base (1), a sliding mechanism (2), a printing bottom plate (3), and a storage unit for contact plate (4). The sliding mechanism (2) comprises: a slide rail (21) fixed, in a left-right orientation, to the base; a first slider (22) and a second slider (23) slidably mounted on the slide rail (21), the first slider (22) being to the left of the second slider (23); and a driving device used for driving the sliders. The printing bottom plate (3) is fixedly mounted on the first slider (22). The printing bottom plate (3) comprises a bottom plate support (31), and sliding grooves are symmetrically disposed at front and rear sides of the bottom plate support (31), such that a contact plate moves in the direction of the sliding grooves. The sliding grooves are provided with a stopping member (32) for fixing the contact plate. The storage unit for contact plate (4) is fixedly mounted on the second slider (23) and comprises a storage box (41) and a stopping block (42). When the 3D printing bottom plate system is used to replace a contact plate, the printing bottom plate (3) reciprocates twice or more in a left-right movement, such that the contact plate is replaced automatically, reducing printing time and improving printing efficiency.
