3D printer for conveniently printing oval workpiece

Abstract

The invention relates to a 3D printer for printing oval-shaped workpieces, which includes a feeding mechanism, a casing, a power mechanism, a nozzle, a printing table and a base, and the base also includes a driving device, and the driving device includes a lifting mechanism, a translation mechanism and an analog audio signal Output module, the lifting mechanism includes a lifting platform, a first motor, a first cylindrical gear and a lifting assembly, the translation mechanism includes a second motor, a half gear, a rack and a drive frame, and the analog audio signal output module includes a third motor, a third cylindrical The gear, the fourth cylindrical gear, the rotating shaft and the second bearing. This is a 3D printer that is convenient for printing oval workpieces. The nozzle does not move, and the printing table performs reciprocating motion while rotating. When it rotates once, it does a linear reciprocating motion in the horizontal direction. Movement, so as to realize the printing of ellipse shape. At the same time, the lifting mechanism can drive the printing platform to lift up and down to print in multiple layers, so as to realize the printing of three-dimensional objects with elliptical elements. This printing method can print ellipses with high precision and fast printing speed.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a 3D printer for printing oval workpieces. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. [0003] At present, when the existing 3D printers want to print an ellipse shape, because it only relies on the movement in the X-axis and Y-axis directions, there will be a certain deviation in accuracy, resulting in an inaccurate printed ellipse and a slow printing speed. , if it is necessary to print a large number of three-dimensional objects with elliptical elements, the printing efficiency of the finished product will be very low. In the process of video signal analy...

[0003] At present, when the existing 3D printers want to print an ellipse shape, because they only rely on the movement in the X-axis and Y-axis directions, there will be a certain deviation in accuracy, resulting in the printed ellipse being not accurate enough, and the printing speed is slow , if it is necessary to print a large number of three-dimensional objects with elliptical elements, the printing efficiency of the finished product will be very low

In the process of video signal analysis and control, due to the lack of functions such as signal enhancement and denoising, the reliability of video processing is greatly reduced, and the reliability of the system is further reduced
