Multi-nozzle 3D printed teaching aid

Abstract

The invention provides a multi-nozzle 3D printed teaching aid. The multi-nozzle 3D printed teaching aid comprises a cubic hollow support, a workbench located in the hollow support and a lifting mechanism connected with the workbench to make the workbench rise and fall, supporting plates are arranged at four corners above the hollow support, a working area is formed among the four supporting plates, every supporting plate is provided with a fixed connection block, a power transmission mechanism and a horizontal plane translation mechanism connected with the power transmission mechanism are arranged between every adjacent two fixed connection blocks, every horizontal plane translation mechanism is provided with a nozzle assembly, and the power transmission mechanisms work and drive the horizontal plane translation mechanisms to move in order to make the nozzle assembly complete X-axial and Y-axial movement in the horizontal direction in the working area formed among the supporting plates. The multi-nozzle 3D printed teaching aid has the advantages of simple structure, control of the movement of the nozzle on the horizontal plane by controlling a driving motor, and control of the height of the workbench through a control motor.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to a multi-nozzle 3D printing teaching aid. Background technique [0002] At present, 3D printing technology has attracted more and more attention from the market. It belongs to the category of additive manufacturing, which originates from rapid prototyping and rapid manufacturing. 3D printing not only fundamentally changed the traditional "cutting and removing material" (subtractive manufacturing) process mode, but also opened a new era represented by "intelligent digitalization". 3D printing technology is known as an important symbol of the third industrial revolution, and European and American countries have long listed it as an important development industry. China got involved in this emerging field relatively late, and it was not until the past two years that it began to pay attention to the development of this new technology. The country called for the vigorous developm...

Problems solved by technology

At this stage, the general 3D printing teaching aids have complex structures and high production costs, which are not conducive to popularization.

In the patent document with the application number 201510556924.4, a multi-nozzle 3D printer is disclosed. The number of nozzles in the device is multiple, but the multiple nozzles are placed in parallel. The disadvantages are: 1. The length is long, which leads to larger in size

2. When the beam connected with multiple nozzles moves in one direction, the multiple nozzles move in the same direction at the same speed, each nozzle cannot move independently, and the ability to work together is poor
