Novel 3D (3-dimentional) printer

Abstract

The invention relates to a novel 3D (3-dimentional) printer. The novel 3D printer comprises an excess material warning device, an external material receiving device, a multi-color printing spraying head device, a printing detection device, a 3D printer rack, a 3D printing material, a 3D printer material tray, a controller, an X-axis stepping motor, a Y-axis stepping motor, a Z-axis stepping motor, an X-axis synchronous belt, a Y-axis synchronous belt, a Z-axis transmission shaft and an alarm device; the excess material warning device can automatically remind workers of timely replacing materials; when printed materials are insufficient, standby materials are connected with existing materials by the external material receiving device, and therefore, the whole printing process can be finished continuously; different printing spraying heads are automatically exchanged to achieve the multi-color printing when the multi-color printing spraying head device works; the printing detection device is adopted to measure the rotating angles of the X-axis stepping motor, the Y-axis stepping motor and the Z-axis stepping motor, so as to detect whether a silk discharging route of each printing spraying head is deviated, and if the silk discharging route of each printing spraying head is deviated, an alarm is given, so that the defective rate of the printed models is reduced and the printing cost and the printing time are saved.

Description

technical field [0001] The invention relates to a novel 3D printer, which belongs to the technical field of three-dimensional printing. Background technique [0002] 3D printer is a technical achievement of digital additive technology gradually moving towards the civilian market after decades of development. Its promotion not only means the advancement of science and technology, but also adds new connotations to the concept of industrial manufacturing, and has broad development prospects. 3D printers use different materials to print three-dimensional models, and there are many types of raw materials for printing, such as plastics and rubber. During the working process, the raw material is heated to a molten state by means of electric heating in the nozzle, and the 3D printer controls the nozzle in the X-Y-Z Movement in three directions, so that the nozzle will discharge the filament according to a certain path, and the sprayed molten filament will be bonded to the workbenc...

AI Technical Summary

Problems solved by technology

[0003] 1) If the remaining material is not enough to support the complete model, the printing will be interrupted in the middle, which will affect the continuity of the printing work. At present, the operator usually needs to watch in real time, and replace it in time when the remaining material is insufficient, which makes the automation of the 3D printer low. , increasing the workload of the operator;

[0004] 2) It is basically a single-color, single-motor, and single-nozzle head. When multi-color printing is required, multiple printers need to be exchanged or materials replaced, and the operation process is very cumbersome;

[0005] 3) Since the wire output path of the print head is determined by the stepping motor in the three directions of X-Y-Z, the X and Y directions control the front, rear, left, and right paths of the print head through the synchronous belt, and the Z axis controls the up and down of the printing table through the transmission shaft position, then the printing accuracy of the 3D printer depends entirely on the control accuracy of the stepper motors in the three directions. Deviation, so that the printed model becomes a defective product, resulting in waste of materials and time
