Novel 3D printer

Abstract

The invention provides a novel 3D printer. The novel 3D printer is composed of a shell part, a Z-axis system, a right Y-axis system, a left Y-axis system, an X-axis system, a printing system and an electric control system. The shell part is designed to be of an integrated streamline structure. A shell box (1) and an upper cover (2) are provided with various integrated connecting structural parts.The Z-axis system, the right Y-axis system, the left Y-axis system, the X-axis system, the printing system, the electric control system and a shell are integrated. The upper cover (2) can rotate around a hinge pin (3) and is positioned through a positioning sliding block (60), a positioning rod (61) and a positioning hole (80). A left screw shaft (5) is of a right-hand thread structure. A right screw shaft (11) is of a left-hand thread structure. The Z-axis system is designed to be provided with a manual rotating wheel (12). A drag chain (26) is designed in the Y-axis direction. A drag chain (18) is designed in the X-axis direction. A printing tray rack (34) is provided with a limiting groove. A touch control screen (38) is provided with a Chinese-English interface.

Description

technical field [0001] The present invention relates to a novel 3D printer, in particular to a clamshell type novel 3D printer. Background technique [0002] At present, the known 3D printers, especially the small and medium-sized 3D printers of fused deposition modeling, have many problems: most of the wire reels are hung outside the rear and the bottom, and the printing wire is connected to the print head above the printer through the wire guide tube. It is inconvenient to observe, it is difficult to change the filament, the resistance of the print head is large when it is working, and it is prone to out of step; all the cables connected to the electrical appliances and components on the X and Y axes have to be dragged back and forth with the print head at will, and there is no tow cable device. The cable is easy to be scratched and jammed, causing mechanical damage; the single Y-axis design, the transmission shaft is slender and easy to bend and deform; the printing tray ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome many problems existing in existing 3D printers, the present invention provides a new type of 3D printer. The new type of 3D printer: a new type of shell is designed. It is convenient for printing, and it is easy to display and carry when it is put away; in order to prevent the wire reel from falling off during operation, the thread of the left screw shaft is designed to be right-handed, and the thread of the right screw shaft is designed to be left-handed; in order to reduce the frictional resistance between the wire reel and the screw shaft, The screw shaft is designed and manufactured with self-lubricating materials; in order to ensure that the wire feeding of the print head does not scratch, the design uses a large arc transition type wire inlet print head; The drag chain is added in the design, and all dynamically running cables are installed in the drag chain; in order to solve the serious problem of bending and deformation of the single Y-axis drive shaft, the Y-axis system is designed as a double Y-axis structure; in order to solve the difficulty of mold ejection and prevent mold ejection Damage to the tray and injury to the equipment, the design adds a limit tray rack and a heat-resistant glass tray
