Rapid arc edge printing device and printing method for 3D printer

Abstract

The invention discloses a rapid arc edge printing device and printing method for a 3D printer. The rapid arc edge printing device comprises a fixed shaft rotating device. Arm unfolding adjusting devices are arranged on the left and right sides of the lower end of the fixed shaft rotating device, and the lower ends of the arm unfolding adjusting devices are connected with arc edge printing heads. Arc edge printing head telescopic devices are disposed between the arm unfolding adjustment devices and the arc edge printing heads, and a print center main head is disposed at the center position of aconnecting line of the two arc edge printing head. A combination mode of a plurality of printing heads for printing is realized by free matching of the fixed shaft rotating device, the arm unfoldingadjustment devices and the arc edge printing head telescopic devices, so as to achieve accurate, rapid and stable printing of an arc edge conveniently and freely and realize complete and non-completeand regular and irregular arc edge printing; and the various requirements of existing products are satisfied when printing, and the problems such as large printing difficulty, complicated process andlow printing speed of existing 3D arc edge printing are solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a rapid arc edge printing device and a printing method of a 3D printer. Background technique [0002] Fused deposition 3D printing technology is a kind of rapid prototyping technology. Its basic working principle is to process the three-dimensional product model established in the computer in layers to obtain several two-dimensional plane graphics, and then use the wire feeding mechanism of the nozzle to transfer the thermoplastic material Send it to the nozzle and heat it to a molten state. Then, according to the contour information of the two-dimensional plane figure, under the control of the computer, the molten material is extruded from the tiny holes of the nozzle to print these two-dimensional plane figures layer by layer. After layer-by-layer stacking Form a three-dimensional solid model. [0003] The current working method of 3D printers is to use the motor to drive ...

AI Technical Summary

Problems solved by technology

[0008] (1) The existing 3D arc edge printing requires the rapid movement of the print head and the printing base plate to print the arc edge more accurately. The printing is difficult, the process is complicated, and the printing speed is slow;

[0009] (2) The existing 3D arc-edge printing uses a multi-sided infinite approach to print out arcs, which may be constrained by external hardware facilities, resulting in slight deviations in the matching accuracy of the printed arcs during the stacking process, which affects printing Effect
