Design of a New Six-Degree-of-Freedom FDM Printer Structure Scheme
As one of the most widely used key technologies in the manufacturing industry,FDM technology(Fused Deposition Modelling)produces a large number of support structures in the process of printing overhanging and complex geometrical shapes of prototype parts,which will cause the waste of printing filament and reduce the efficiency of printing,and at the same time lead to the reduction of the quality of the surface of the products printed as well as heavy post-processing of the products.Based on the FDM gantry structure,a new six-degree-of-freedom FDM printer structure design scheme is proposed by increasing two rotational degrees of freedom of the printing platform and one rotational degree of freedom of the printhead;and the transmission structure of the printing platform and the printhead is further designed in three-dimensional structure;finally,simulation tests are carried out on the model,which verifies that the device can effectively reduce the effect of the support structure,and this proposes a new structural optimization scheme for FDM printers.This puts forward a new development idea for the optimisation of the printer structure design.
