3D printer with power failure continuous printing function and printing method

Abstract

The invention provides a 3D printer with a power failure continuous printing function and a printing method.The 3D printer comprises a 3D printing actuator which comprises an extrusion head, the 3D printer further comprises a power failure monitoring control unit, a power failure data storage unit and an extrusion head heating module, when the power failure monitoring control unit monitors that power supply of the 3D printing actuator is broken off, power failure data are recorded to the power failure data storage unit, when the power supply of the 3D printing actuator is monitored to be recovered, whether power failure data are stored is detected, when corresponding power failure data are detected, the extrusion head is preheated, mechanical resetting is performed to the 3D printing actuator until the adhering part of the extrusion head and an unfinished printing module is melted, and printing is carried out.The preheated extrusion head is printed continuously, the extrusion head and the unfinished module are separated, and the printing module can be prevented from being pulled and damaged during continuous printing.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a 3D printer and a printing method with the function of continuous printing after power failure. Background technique [0002] FDM (Fused Deposition Modeling, Fused Deposition Modeling) 3D printers can take hours or days to print a model. If an unexpected power outage occurs during printing, the printer will interrupt printing. If no continuous printing measures are taken, half or even more than half of the models that have been printed in the early stage can only be scrapped, resulting in a lot of waste of consumables and time. [0003] At present, some manufacturers of FDM3D printers have conducted research to solve the above problems. But they mainly adopt the way of external backup power supply, which undoubtedly greatly increases the hardware cost, volume, and affects the appearance of the whole machine. [0004] The prior art such as the Chinese patent publication CN103921446A discloses a...

Problems solved by technology

If this happens, the next time the extrusion head fires up it can damage the sticky parts or even uproot the entire model

On the other hand, when the operator manually repairs the traces of the breakpoint, he can only rely on experience and the naked eye to find the location of the power failure, which is time-consuming and labor-intensive
