Abstract

The invention discloses a 3D printing machine with multiple printing heads. The 3D printing machine comprises a stander, a movable worktable which is used for storing a workpiece, a printing head mechanism for printing the workpiece, a plurality of material boxes for supplying printing materials to the printing heads, and a control system for controlling each components, wherein the movable worktable and the printing head mechanism are correspondently arranged in the stander; the printing head mechanism comprises a disc seat body which is arranged on the stander, and a plurality of lifting adjusting mechanisms which are uniformly distributed on the disc seat body, each lifting adjusting mechanism is provided with the printing head, and the disc seat body is driven by a motor to rotate; the printing heads correspond to the material boxes one by one. By adopting the 3D printing machine with the multiple printing heads, the different materials can be rapidly replaced, the material replacing time can be effectively shortened, and the operating efficiency can be improved; the reliability in action and the rapidness in reaction can be realized, the reliability is high, the overall structure is simple, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of three-dimensional manufacturing and relates to a 3D printer with multiple printing heads. Background technique [0002] The material selected in the melt extrusion molding (FDM) process is generally a thermoplastic material and is fed in a filamentary form, such as wax, ABS, PC, nylon, etc. The material is heated and melted in the nozzle, and the nozzle moves along the section profile of the part and the filling trajectory , while extruding the molten material, the material solidifies rapidly and bonds with the surrounding materials. Each layer in this process is accumulated on the previous layer, so the previous layer plays a role in positioning and supporting the current layer; as the height increases, the area and shape of the layer profile will change , when the shape changes greatly, the upper profile cannot provide sufficient positioning and support for the current layer, which requires the design of some au...
