A desktop 3D printer multifunctional bottom plate

Abstract

The invention provides a multi-functional bottom plate of a tabletop type 3D printer. The multi-functional bottom plate comprises a heating plate, a heat preservation induction plate, a thermal insulation plate, a support plate, a carrier plate and a support, wherein the topmost layer is the heat preservation induction plate, the heating plate is arranged below the heat preservation induction plate, the thermal insulation plate is arranged below the heating plate, the support plate is arranged below the thermal insulation plate, and the carrier plate and the support are arranged below the support plate; an LED lamp is mounted on the heat preservation induction plate, the heating plate adopts a net-shaped hollow structure in which resistance wires are mounted, and a weight measurement induction device and a positioning system are arranged in the support plate. When a 3D product is printed, the temperature of the bottom plate can be measured and controlled, the weight of the product can be measured, and the print speed can be controlled. At the same time, the coordinates of the bottom plate can be tracked, and the print precision can be effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of 3D printing additive manufacturing, and in particular relates to a multifunctional base plate of a desktop 3D printer. technical background [0002] 3D printing technology, that is, additive manufacturing technology, is a revolutionary advanced green intelligent manufacturing technology that has developed rapidly in recent years. It is a manufacturing technology based on the principle of discrete and stacking. It discretizes the three-dimensional computer-aided design (CAD) model of the part in a certain way, and becomes a machinable discrete surface, discrete line and discrete point, and then uses physical or chemical means. These discrete surfaces, line segments and points are piled up to form a part shape. 3D printing technology can automatically and quickly transform the designed 3D CAD model into a prototype with a certain structure and function or directly manufacture parts through the superpositio...

AI Technical Summary

Problems solved by technology

[0005] (1) The bottom plate of the desktop 3D printer only has a heating function, and the heating temperature stability is poor, and the contact position between the product and the bottom plate is prone to warping;

[0006] (2) There is no product weight measuring device on the bottom plate of the desktop 3D printer, which cannot realize real-time monitoring of product quality;

[0007] (3) There is no positioning system for the bottom plate of the desktop 3D printer, and the coordinates of the bottom plate cannot be tracked in real time, so it is difficult to control the printing accuracy
