Modular 3D printer

Abstract

The invention discloses a modular 3D printer. The modular 3D printer comprises an outer shell frame, a front panel and a rear panel are arranged on the outer shell frame, and a printer mechanism is fixedly arranged in the outer shell frame. In the printer mechanism, a lower substrate is fixedly connected with an upper substrate through connecting columns; guide sleeves and a lead screw nut are arranged on the side face of a printing object holding table, a lead screw matched with the lead screw nut is arranged between the upper substrate and the lower substrate, the axis of the lead screw is parallel to the axes of the connecting columns, and a lifting motor is arranged on the upper substrate; a positioning driving motor is arranged on the lower surface of the upper substrate, a printing positioning component is arranged on the upper surface of the upper substrate, and a printing head is arranged on the printing positioning component. According to the invention, the independent mechanism is arranged, then the mechanism is arranged in the outer shell frame, and therefore when the 3D printer is produced, part assembling is convenient, the precision of the whole printer mechanism is high, and the printing precision is also high. Meanwhile, when the 3D printer needs to be maintained or fails, the whole printer mechanism can be taken out of the outer shell frame, and inspection or maintenance is facilitated.

Description

technical field [0001] The invention belongs to the field of 3D printers, and in particular relates to a modular 3D printer. Background technique [0002] 3D printing is a new type of molding technology, a new technology that forms a three-dimensional object through continuous deposition of printing materials. Currently common 3D printers, the internal components are directly installed on the 3D printer shell. When the printer is assembled, it is necessary to put each component into the casing and then install it fixedly, which makes the assembly difficult. At the same time, the internal components are directly installed on the shell of the 3D printer, which makes the 3D printer susceptible to external force interference during printing, which affects the printing accuracy and effect. It will cause poor printing and high printing scrap rate, thereby increasing the difficulty and cost of the user's use. In the current common 3D printers, each component is put into the shel...

AI Technical Summary

Problems solved by technology

When the printer is assembled, it is necessary to put each component into the shell and then install it fixedly, which makes the assembly difficult

At the same time, the internal components are directly installed on the shell of the 3D printer, which makes the 3D printer susceptible to external force interference during printing and affects the printing accuracy and effect.

It will cause poor printing and higher printing scrap rate, which will increase the difficulty and cost of users' use

In the current common 3D printers, each component is put into the shell and then fixedly installed, which will also make the daily internal maintenance and troubleshooting of the printer very inconvenient.
