Abstract

The invention discloses a 3D printing method and a 3D printer, and relates to the technical field of 3D printing. The 3D printing method includes the following steps: determining current printing data according to a printing model, and the current printing data includes the current printing unit at the current printing position at least one of the thickness and width of the 3D printer; determine the control parameters of the 3D printer according to the current printing data, the control parameters include the target moving speed of the nozzle of the 3D printer, the target printing height of the nozzle and the at least one of the target wire feeding speed of the nozzle; controlling the 3D printer to print the current printing unit according to the control parameter. The invention solves the problem of step effect in the existing 3D printing method, realizes the real-time adaptive regulation of the cross-sectional shape and size of the fuse wire, reduces the surface roughness of the workpiece, and improves the surface geometric quality of the workpiece.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing method and a 3D printer. Background technique [0002] At present, 3D printing, that is, the additive manufacturing of Material Extrusion (ME) forming, uses a nozzle with a constant diameter to heat and melt a filament with a constant diameter passing through the nozzle to form a cross-sectional shape and a fixed size. The fuses are accumulated on the surface of the part, accumulated layer by layer, and finally form the three-dimensional shape of the part (such as figure 1 As shown), the irregular parts manufactured by this method have obvious step effect on the inclined surface, which seriously affects the dimensional accuracy and surface roughness of the part. In order to overcome the above shortcomings, relevant researchers at home and abroad have successively proposed curved layer fused deposition modeling (CLFDM) process methods and conformal surface layer...
