The structure of the slide rail 4 is not limited. In some embodiments, referring to fig. 4A and 4B, a surface of the side of the sliding rail 4 facing the printing platform assembly 5 is a plane, that is, no groove is formed on the surface of the side of the sliding rail 4 facing the printing platform assembly 5, so as to prevent residue or dust of consumables on the printing platform from falling into the groove. The slide rail 4 may further be provided with a through groove 42 penetrating through two ends of the slide rail 4, and the through groove 42 may be used for passing a conducting wire for conducting electricity, or for passing a belt, etc. The thickness of the partial or whole part of the slide rail 4 can be increased according to the needs to increase the strength of the slide rail 4, so that the slide rail 4 is not easy to deform.
Referring to fig. 5, the present application further provides a 3D printer, and the 3D printer includes the above-mentioned base. The 3D printer may be any kind of existing 3D printer, or other 3D printers developed in the future.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
